        fData = contents;
        fGrammar = grammar;
Methods Summary
public java.lang.StringgetAnnotationString()
A text representation of annotation.

        return fData;
public java.lang.StringgetName()
The name of type NCName of this declaration as defined in XML Namespaces.

        return null;
public java.lang.StringgetNamespace()
The [target namespace] of this object, or null if it is unspecified.

        return null;
public org.apache.xerces.xs.XSNamespaceItemgetNamespaceItem()
A namespace schema information item corresponding to the target namespace of the component, if it's globally declared; or null otherwise.

        return null;
public shortgetType()
The type of this object, i.e. ELEMENT_DECLARATION.

        return XSConstants.ANNOTATION;
public booleanwriteAnnotation(java.lang.Object target, short targetType)
Write contents of the annotation to the specified DOM object. If the specified target object is a DOM in-scope namespace declarations for annotation element are added as attributes nodes of the serialized annotation, otherwise the corresponding events for all in-scope namespace declaration are sent via specified document handler.

param
target A target pointer to the annotation target object, i.e. org.w3c.dom.Document, org.xml.sax.ContentHandler.
param
targetType A target type.
return
If the target is recognized type and supported by this implementation return true, otherwise return false.
