Method Detail

fireSelectionChanged

public void fireSelectionChanged(ViperSubTreeChangedEvent e)

This should be used instead of fireChangeEvent.

Parameters:

e -

isFilteredBy

public boolean isFilteredBy(java.lang.Class type)

Description copied from interface: ViperSubTree

Only nodes beneath some subset of the nodes of the specified type are selected.

Specified by:

isFilteredBy in interface ViperSubTree

Parameters:

type - one of the viper.api interfaces, e.g. Sourcefile.class

Returns:

false if there is no filtering by the given type (i.e. all children of selected parents are selected)

See Also:

ViperSubTree.isFilteredBy(java.lang.Class)

fireChangeEvent

public void fireChangeEvent(javax.swing.event.ChangeEvent e)

Description copied from class: AbstractViperSelection

Fire a change event to all registered listeners.

Overrides:

fireChangeEvent in class AbstractViperSelection

Parameters:

e - null if you wish to use a default change event, with this as the source

See Also:

AbstractViperSelection.fireChangeEvent(javax.swing.event.ChangeEvent)

toString

public java.lang.String toString()

Prints out the subtree as a chain.

Returns:

subtree in the form of [ {nodetype: nodes}* ]

getSelectedBy

public java.util.Iterator getSelectedBy(java.lang.Class c)

Description copied from interface: ViperSubTree

Gets the selections of the given viper node type.

Specified by:

getSelectedBy in interface ViperSubTree

Parameters:

c - the node type, e.g. Sourcefile.class

Returns:

an iterator over all, if any, nodes are specifically selected in the tree of the given type

isEmpty

public boolean isEmpty()

Description copied from interface: ViperSelection

Tests to see if something is selected.

Specified by:

isEmpty in interface ViperSelection

Returns:

if anything is selected
