Method Detail

isReadOnly

public boolean isReadOnly()

Description copied from class: RuleModellerWidget

Dictates if the widget's state is RO or not. Sometimes RuleModeller will force this state (i.e. when lockLHS() or lockRHS()), but some other times, the widget itself is responsible to autodetect its state.

Specified by:

isReadOnly in class RuleModellerWidget

Returns:

isFactTypeKnown

public boolean isFactTypeKnown()

Description copied from class: RuleModellerWidget

Does the Fact Type the Widget represents known to the SuggestionCompletionEngine. If the Fact Type is known the Widget can be edited or deleted (unless read-only). If the Fact Type is not known the Widget can be deleted but cannot be edited (i.e. it is always read-only).

Specified by:

isFactTypeKnown in class RuleModellerWidget

Returns:

addExpressionTypeChangeHandler

public com.google.gwt.event.shared.HandlerRegistration addExpressionTypeChangeHandler(ExpressionTypeChangeHandler handler)

Specified by:

addExpressionTypeChangeHandler in interface HasExpressionTypeChangeHandlers

addExpressionChangeHandler

public com.google.gwt.event.shared.HandlerRegistration addExpressionChangeHandler(ExpressionChangeHandler handler)

Specified by:
