Constructor Detail

ViewSizing

public ViewSizing()

Constructor that uses a default row height and column width. The default row height is 10. The default column width is 10. At this point, no attributes have been explicitly set.

ViewSizing

public ViewSizing(int rowHeight,
                  int columnWidth)

Constructor that specifies a particular row height and column width. At this point, no attributes have been explicitly set.

Parameters:

rowHeight - The initial value for the height of a row.

columnWidth - The initial value for the width of a column.

Method Detail

isAnythingOverridden

public boolean isAnythingOverridden()

Indicates whether any of the attributes of this ViewSizing object has been explicitly set.

Specified by:

isAnythingOverridden in interface Mergeable

Returns:

true if any attribute has been explicitly set, false if the attributes have their original values.

clone

public java.lang.Object clone()

Clones this ViewSizing object.

Specified by:

clone in interface Mergeable

Overrides:

clone in class java.lang.Object

Returns:

The ViewSizing clone.

setRowHeight

public void setRowHeight(int rowHeight)

Specifies the row height for this object. This method also sets the setRowHeightUsed method to true.

Parameters:

rowHeight - The row height for this object.

getRowHeight

public int getRowHeight()

Retrieves the row height property for this object.

Returns:

The row height for this object.

isRowHeightUsed

public boolean isRowHeightUsed()

Indicates whether the RowHeight attribute has been explicitly set. When this method's return value is true, the attribute's value will be used in the merging process.

Returns:

true if the attribute has been explicitly set, false if it has not been explicitly set.

setRowHeightUsed

public void setRowHeightUsed(boolean used)

Specifies whether the RowHeight attribute has been explicitly set. This method is set by the setRowHeight attribute. When the parameter value of this method is set to true, the attribute's value will be used in the merging process.

Parameters:

used - true if the attribute has been explicitly set, false if it has not been explicitly set.

setColumnWidth

public void setColumnWidth(int columnWidth)

Specifies the width for the columns of this object. This method also sets the setColumnWidthUsed method to true.

Parameters:

columnWidth - The width for the columns of this object.

getColumnWidth

public int getColumnWidth()

Retrieves the width for the columns of this object.

Returns:

The width for the columns of this object.

isColumnWidthUsed

public boolean isColumnWidthUsed()

Indicates whether the ColumnWidth attribute has been explicitly set. When the returns value of this method is true, the attribute's value will be used in the merging process.

Returns:

true if the attribute has been explicitly se, false if it has not been explicitly se.

setColumnWidthUsed

public void setColumnWidthUsed(boolean used)

Specifies whether the ColumnWidth attribute has been explicitly set. This method is set by the setColumnWidth attribute. When the parameter value of this method is set to true, the attribute's value will be used in the merging process.

Parameters:

used - true if the attribute has been explicitly set, false if it has not been explicitly set.

merge

public void merge(Mergeable from)

Merges the specified ViewSizing object with this object. This method is called by the Rule classes.

Specified by:

merge in interface Mergeable

Parameters:

from - The ViewSizing object that you want to merge.

equals

public boolean equals(java.lang.Object o)

Indicates whether the specified object is equivalent to this ViewSizing object. Objects are equivalent if they have the same attributes explicitly set and those attributes have the same values.

Overrides:

equals in class java.lang.Object

Parameters:

o - The object that you want to compare with this ViewSizing object.

Returns:

true if they are equal, false if not, or if o is not a ViewSizing object.

clearUsedBits

public void clearUsedBits()

Sets all of the "used" ViewSizing attributes to false. Immediately after you call this method, the IsAnythingOverridden method returns false.
