                   throws java.sql.SQLException
Construct a FilteredRowSet with a specified synchronization provider.

Parameters:
env - a Hashtable containing a desired synchconizatation provider name-value pair.
Method Detail

setFilter

public void setFilter(Predicate p)
               throws java.sql.SQLException
Apply the predicate for this filter

Specified by:
setFilter in interface FilteredRowSet
Parameters:
p - an implementation of the predicate interface
Throws:
java.sql.SQLException - if an error occurs when setting the Predicate object

getFilter

public Predicate getFilter()
Retrieve the filter active for this FilteredRowSet

Specified by:
getFilter in interface FilteredRowSet
Returns:
a Predicate object instance

internalNext

protected boolean internalNext()
                        throws java.sql.SQLException
Over-riding internalNext() implementation. This method applies the filter on the RowSet each time the cursor is advanced or manipulated. It moves the cursor to the next row according to the set predicate and returns true if the cursor is still within the rowset or false if the cursor position is over the last row

Overrides:
internalNext in class CachedRowSetImpl
Returns:
true if over the valid row in the rowset; false if over the last row
Throws:
java.sql.SQLException - if an error occurs

internalPrevious

protected boolean internalPrevious()
                            throws java.sql.SQLException
Over-riding internalPrevious() implementation. This method applies the filter on the RowSet each time the cursor is moved backward or manipulated. It moves the cursor to the previous row according to the set predicate and returns true if the cursor is still within the rowset or false if the cursor position is over the last row

Overrides:
internalPrevious in class CachedRowSetImpl
Returns:
true if over the valid row in the rowset; false if over the last row
Throws:
java.sql.SQLException - if an error occurs

internalFirst

protected boolean internalFirst()
                         throws java.sql.SQLException
Over-riding internalFirst() implementation. This method applies the filter on the RowSet each time the cursor is moved to first row. It moves the cursor to the first row according to the set predicate and returns true if the cursor is still within the rowset or false if the cursor position is over the last row

Overrides:
internalFirst in class CachedRowSetImpl
Returns:
true if over the valid row in the rowset; false if over the last row
Throws:
java.sql.SQLException - if an error occurs

internalLast

protected boolean internalLast()
                        throws java.sql.SQLException
Over-riding internalLast() implementation. This method applies the filter on the RowSet each time the cursor is moved to last row. It moves the cursor to the last row according to the set predicate and returns true if the cursor is still within the rowset or false if the cursor position is over the last row

Overrides:
internalLast in class CachedRowSetImpl
Returns:
true if over the valid row in the rowset; false if over the last row
Throws:
java.sql.SQLException - if an error occurs

relative

public boolean relative(int rows)
                 throws java.sql.SQLException
Moves the cursor the specified number of rows from the current position, with a positive number moving it forward and a negative number moving it backward.

If the number is positive, the cursor moves the specified number of rows toward the end of the rowset, starting at the current row. For example, the following command, in which crs is a CachedRowSetImpl object with 100 rows, moves the cursor forward four rows from the current row. If the current row is 50, the cursor would move to row 54. 



    crs.relative(4);

If the number is negative, the cursor moves back toward the beginning the specified number of rows, starting at the current row. For example, calling the method absolute(-1) positions the cursor on the last row, absolute(-2) moves it on the next-to-last row, and so on. If the CachedRowSetImpl object crs has five rows, the following command moves the cursor to the fourth-to-last row, which in the case of a rowset with five rows, is also the second row from the beginning. 



    crs.absolute(-4);
If the number specified is larger than the number of rows, the cursor will move to the position after the last row. If the number specified would move the cursor one or more rows before the first row, the cursor moves to the position before the first row. In both cases, this method throws an SQLException.

Note: Calling absolute(1) is the same as calling the method first(). Calling absolute(-1) is the same as calling last(). Calling relative(0) is valid, but it does not change the cursor position.

Specified by:
relative in interface java.sql.ResultSet
Overrides:
relative in class CachedRowSetImpl
Parameters:
rows - an int indicating the number of rows to move the cursor, starting at the current row; a positive number moves the cursor forward; a negative number moves the cursor backward; must not move the cursor past the valid rows
Returns:
true if the cursor is on a row in this CachedRowSetImpl object; false otherwise
Throws:
java.sql.SQLException - if the rowset is type ResultSet.TYPE_FORWARD_ONLY

absolute

public boolean absolute(int rows)
                 throws java.sql.SQLException
Moves this CachedRowSetImpl object's cursor to the row number specified.

If the number is positive, the cursor moves to an absolute row with respect to the beginning of the rowset. The first row is row 1, the second is row 2, and so on. For example, the following command, in which crs is a CachedRowSetImpl object, moves the cursor to the fourth row, starting from the beginning of the rowset. 



    crs.absolute(4);

If the number is negative, the cursor moves to an absolute row position with respect to the end of the rowset. For example, calling absolute(-1) positions the cursor on the last row, absolute(-2) moves it on the next-to-last row, and so on. If the CachedRowSetImpl object crs has five rows, the following command moves the cursor to the fourth-to-last row, which in the case of a rowset with five rows, is also the second row, counting from the beginning. 



    crs.absolute(-4);
If the number specified is larger than the number of rows, the cursor will move to the position after the last row. If the number specified would move the cursor one or more rows before the first row, the cursor moves to the position before the first row.

Note: Calling absolute(1) is the same as calling the method first(). Calling absolute(-1) is the same as calling last().

Specified by:
absolute in interface java.sql.ResultSet
Overrides:
absolute in class CachedRowSetImpl
Parameters:
rows - a positive number to indicate the row, starting row numbering from the first row, which is 1; a negative number to indicate the row, starting row numbering from the last row, which is -1; it must not be 0
Returns:
true if the cursor is on the rowset; false otherwise
Throws:
java.sql.SQLException - if the given cursor position is 0 or the type of this rowset is ResultSet.TYPE_FORWARD_ONLY

moveToInsertRow

public void moveToInsertRow()
                     throws java.sql.SQLException
Moves the cursor for this CachedRowSetImpl object to the insert row. The current row in the rowset is remembered while the cursor is on the insert row.

The insert row is a special row associated with an updatable rowset. It is essentially a buffer where a new row may be constructed by calling the appropriate updateXXX methods to assign a value to each column in the row. A complete row must be constructed; that is, every column that is not nullable must be assigned a value. In order for the new row to become part of this rowset, the method insertRow must be called before the cursor is moved back to the rowset.

Only certain methods may be invoked while the cursor is on the insert row; many methods throw an exception if they are called while the cursor is there. In addition to the updateXXX and insertRow methods, only the getXXX methods may be called when the cursor is on the insert row. A getXXX method should be called on a column only after an updateXXX method has been called on that column; otherwise, the value returned is undetermined.

Specified by:
moveToInsertRow in interface java.sql.ResultSet
Overrides:
moveToInsertRow in class CachedRowSetImpl
Throws:
java.sql.SQLException - if this CachedRowSetImpl object is ResultSet.CONCUR_READ_ONLY

updateInt

public void updateInt(int columnIndex,
                      int x)
               throws java.sql.SQLException
Sets the designated column in either the current row or the insert row of this CachedRowSetImpl object with the given int value.

This method updates a column value in the current row or the insert row of this rowset, but it does not update the database. If the cursor is on a row in the rowset, the method CachedRowSetImpl.updateRow() must be called to update the database. If the cursor is on the insert row, the method insertRow() must be called, which will insert the new row into both this rowset and the database. Both of these methods must be called before the cursor moves to another row.

Specified by:
updateInt in interface java.sql.ResultSet
Overrides:
updateInt in class CachedRowSetImpl
Parameters:
columnIndex - the first column is 1, the second is 2, and so on; must be 1 or larger and equal to or less than the number of columns in this rowset
x - the new column value
Throws:
java.sql.SQLException - if (1) the given column index is out of bounds, (2) the cursor is not on one of this rowset's rows or its insert row, or (3) this rowset is ResultSet.CONCUR_READ_ONLY

updateInt

public void updateInt(java.lang.String columnName,
                      int x)
               throws java.sql.SQLException
Sets the designated column in either the current row or the insert row of this CachedRowSetImpl object with the given int value.

This method updates a column value in the current row or the insert row of this rowset, but it does not update the database. If the cursor is on a row in the rowset, the method CachedRowSetImpl.updateRow() must be called to update the database. If the cursor is on the insert row, the method insertRow() must be called, which will insert the new row into both this rowset and the database. Both of these methods must be called before the cursor moves to another row.

Specified by:
updateInt in interface java.sql.ResultSet
Overrides:
updateInt in class CachedRowSetImpl
Parameters:
columnName - a String object that must match the SQL name of a column in this rowset, ignoring case
x - the new column value
Throws:
java.sql.SQLException - if (1) the given column name does not match the name of a column in this rowset, (2) the cursor is not on one of this rowset's rows or its insert row, or (3) this rowset is ResultSet.CONCUR_READ_ONLY

updateBoolean

public void updateBoolean(int columnIndex,
                          boolean x)
                   throws java.sql.SQLException
Sets the designated column in either the current row or the insert row of this CachedRowSetImpl object with the given boolean value.

This method updates a column value in the current row or the insert row of this rowset, but it does not update the database. If the cursor is on a row in the rowset, the method CachedRowSetImpl.updateRow() must be called to update the database. If the cursor is on the insert row, the method insertRow() must be called, which will insert the new row into both this rowset and the database. Both of these methods must be called before the cursor moves to another row.

Specified by:
updateBoolean in interface java.sql.ResultSet
Overrides:
updateBoolean in class CachedRowSetImpl
Parameters:
columnIndex - the first column is 1, the second is 2, and so on; must be 1 or larger and equal to or less than the number of columns in this rowset
x - the new column value
Throws:
java.sql.SQLException - if (1) the given column index is out of bounds, (2) the cursor is not on one of this rowset's rows or its insert row, or (3) this rowset is ResultSet.CONCUR_READ_ONLY

updateBoolean

public void updateBoolean(java.lang.String columnName,
                          boolean x)
                   throws java.sql.SQLException
Sets the designated column in either the current row or the insert row of this CachedRowSetImpl object with the given boolean value.

This method updates a column value in the current row or the insert row of this rowset, but it does not update the database. If the cursor is on a row in the rowset, the method CachedRowSetImpl.updateRow() must be called to update the database. If the cursor is on the insert row, the method insertRow() must be called, which will insert the new row into both this rowset and the database. Both of these methods must be called before the cursor moves to another row.

Specified by:
