Constructor Detail

TreeIntColumn

public TreeIntColumn(String name,
                     Tree tree)

Constructor.

Parameters:

name - column name

tree - associated tree

Method Detail

dispose

public void dispose()

Releases listeners.

get

public int get(int index)

Returns the element at the specified position in this column.

Overrides:

get in class IntColumn

Parameters:

index - index of element to return.

Returns:

the element at the specified position in this column.

size

public int size()

Returns the number of elements in this column.

Specified by:

size in interface Column

Overrides:

size in class IntColumn

Returns:

the number of elements in this column.

iterator

public RowIterator iterator()

Returns a RowIterator over all the valid rows of this column.

Specified by:

iterator in interface Column

Overrides:

iterator in class BasicColumn

Returns:

a RowIterator over all the valid rows of this column.

toArray

public int[] toArray()

Returns the array of integer values used by the column. BEWARE! no copy is done for performance reasons and the array should only be read. It may become out of sync with the column if the column is resized.

Overrides:

toArray in class IntColumn

Returns:

the array of integer values used by the column.

toArray

public int[] toArray(int[] a)

Returns the array of integer values copied from the column.

Overrides:

toArray in class IntColumn

Parameters:

a - an array of int with at least the column size or null.

Returns:

the array of integer values copied from the column.

sort

public void sort(RowComparator comp)

Sort the values of this column according to a comparator.

Overrides:

sort in class IntColumn

Parameters:

comp - the comparator

stableSort

public void stableSort(RowComparator comp)

Sort the values of this column according to a comparator using a stable sort algorithm.

Overrides:

stableSort in class IntColumn

Parameters:

comp - the comparator

getValueReference

public IntArrayList getValueReference()

Returns the DoubleArrayList backing the implementation of the column (USE WITH CARE).

Overrides:

getValueReference in class IntColumn

Returns:

the DoubleArrayList backing the implementation of the column.

validate

public void validate()

Validate the contents of this column if needed.

invalidate

public void invalidate()

Sets the column to invalid.

isInvalid

public boolean isInvalid()

Returns:

Returns the invalid.

treeNodesChanged

public void treeNodesChanged(TreeModelEvent e)

Specified by:

treeNodesChanged in interface TreeModelListener

treeNodesInserted

public void treeNodesInserted(TreeModelEvent e)

Specified by:

treeNodesInserted in interface TreeModelListener

treeNodesRemoved

public void treeNodesRemoved(TreeModelEvent e)

Specified by:

treeNodesRemoved in interface TreeModelListener

treeStructureChanged

public void treeStructureChanged(TreeModelEvent e)

Specified by:

treeStructureChanged in interface TreeModelListener
