Method Detail

fetchProvider

protected java.lang.Object fetchProvider()

Overrides:

fetchProvider in class DCRowSetIteratorImpl

getStructureDef

public StructureDef getStructureDef()

Overrides:

getStructureDef in class DCRowSetIteratorImpl

setName

public void setName(java.lang.String name)

Description copied from class: PropertiesHelper

This method is not implemented by default. subclasses may implement this method.

Overrides:

setName in class RowSetHelper

notifyNavigationEvent

protected final void notifyNavigationEvent(Row srcRow,
                                           Row dstRow)

Overrides:

notifyNavigationEvent in class DCRowSetIteratorImpl

clearCurrentData

public void clearCurrentData()

Description copied from class: DCRowSetIteratorImpl

for internal framework use only. Cleans the current data and rests this iterator. Next call to fetch data will attempt to re-execute the data provider.

Overrides:

clearCurrentData in class DCRowSetIteratorImpl

getMasterRowDataProvider

protected java.lang.Object getMasterRowDataProvider()

Overrides:

getMasterRowDataProvider in class DCRowSetIteratorImpl

createAndInitRow

public Row createAndInitRow(AttributeList nvp)

Description copied from interface: RowIterator

Creates and initializes a new Row object, but does not insert it into the Row Set. This method differs from createRow() mainly in that this method allows the user to pass in a list of name-value pairs with which row attributes are initialized.

nvp is a named value pair. When building an nvp from scratch, use NameValuePairs to build a new nvp. Here is an example:

    NameValuePairs nvp = new NameValuePairs();
    nvp.setAttribute("EmpTyp", "C");

    Row row = voEmp.createAndInitRow(nvp);
 

This method is particularly useful when creating a subclass View Row or Entity Row. You can include polymorphic discriminator attribute values in nvp and correct subclass row object will be created.

When this method is called, underlying entities are created. After the new entities are created, a new view row is created. After that ViewRowImpl.create(oracle.jbo.AttributeList) is called with this nvp. ViewRowImpl.create(AttributeList) walks thru the list of entities and calls EntityImpl.create(AttributeList) with the same nvp for each entity in the view row.

Specified by:

createAndInitRow in interface RowIterator

Overrides:

createAndInitRow in class DCRowSetIteratorImpl

Parameters:

nvp - a list of name-value pairs.

Returns:

a new Row object.

containsRow

protected boolean containsRow(Row row)

Overrides:

containsRow in class DCRowSetIteratorImpl

                                                 java.lang.String name,
                                                 boolean trackMaster)
