Method Detail

clone

public java.lang.Object clone()

Performs a deep clone of the record

Overrides:

clone in class java.lang.Object

insertColumn

public void insertColumn(ColumnInfoRecord col)

Inserts a column into the aggregate (at the end of the list).

visitContainedRecords

public void visitContainedRecords(RecordAggregate.RecordVisitor rv)

Description copied from class: RecordAggregate

Visit each of the atomic BIFF records contained in this RecordAggregate in the order that they should be written to file. Implementors may or may not return the actual Records being used to manage POI's internal implementation. Callers should not assume either way, and therefore only attempt to modify those Records after cloning

Specified by:

visitContainedRecords in class RecordAggregate

collapseColumn

public void collapseColumn(int columnIndex)

expandColumn

public void expandColumn(int columnIndex)

setColumn

public void setColumn(int targetColumnIx,
                      java.lang.Short xfIndex,
                      java.lang.Integer width,
                      java.lang.Integer level,
                      java.lang.Boolean hidden,
                      java.lang.Boolean collapsed)

groupColumnRange

public void groupColumnRange(int fromColumnIx,
                             int toColumnIx,
                             boolean indent)

Creates an outline group for the specified columns, by setting the level field for each col info record in the range. ColumnInfoRecords may be created, split or merged as a result of this operation.

Parameters:

fromColumnIx - group from this column (inclusive)

toColumnIx - group to this column (inclusive)

indent - if true the group will be indented by one level, if false indenting will be decreased by one level.

findColumnInfo

public ColumnInfoRecord findColumnInfo(int columnIndex)

Finds the ColumnInfoRecord which contains the specified columnIndex

Parameters:

columnIndex - index of the column (not the index of the ColumnInfoRecord)

Returns:

null if no column info found for the specified column

getMaxOutlineLevel

public int getMaxOutlineLevel()
