Method Detail

canHandleValue

public boolean canHandleValue(ValueNode valueNode,
                              ValueEditorProvider.SupportInfo providerSupportInfo)

Checks if the value editor provided by this provider can handle a given value node.

Specified by:

Parameters:

valueNode - the value node to check

providerSupportInfo - the support info object threaded through nested calls.

Returns:

true if the provider can handle the value node

getEditorInstance

public AlgebraicValueEditor getEditorInstance(ValueEditorHierarchyManager valueEditorHierarchyManager,
                                              ValueNode valueNode)

Returns an instance of the provided editor. A new instance will be returned every time this method is called and null will never be returned. This method will take construct the value editor and set it's value node, however, it will not call setInitialValue() on the editor. Technically this method should be called after the editor has become the current editor meaning it should be called by the value editor hierarchy manager which determines the current editor.

Specified by:

getEditorInstance in class ValueEditorProvider<AlgebraicValueEditor>

Returns:

ValueEditor
