Method Detail

isMixed

public static boolean isMixed(org.w3c.dom.Node node)
This method checks mixed=true attribute is set either on complexType or complexContent element.


getUnionNode

public static org.w3c.dom.Node getUnionNode(org.w3c.dom.Node node)

getListNode

public static org.w3c.dom.Node getListNode(org.w3c.dom.Node node)

isSimpleTypeWithUnion

public static boolean isSimpleTypeWithUnion(org.w3c.dom.Node node)

isWrappedType

public static boolean isWrappedType(org.w3c.dom.Node node)
This method checks out if the given node satisfies the 3rd condition of the "wrapper" style: such an element (a wrapper) must be of a complex type defined using the xsd:sequence compositor and containing only elements declarations. (excerpt from JAX-RPC spec 1.1 Maintenanace Review 2 Chapter 6 Section 4.1.)

Parameters:
node -
Returns:

getContainedElementDeclarations

public static java.util.Vector getContainedElementDeclarations(org.w3c.dom.Node node,

If the specified node represents a supported JAX-RPC complexType or simpleType, a Vector is returned which contains ElementDecls for the child element names. If the element is a simpleType, an ElementDecls is built representing the restricted type with the special name "value". If the element is a complexType which has simpleContent, an ElementDecl is built representing the extended type with the special name "value". This method does not return attribute names and types (use the getContainedAttributeTypes) If the specified node is not a supported JAX-RPC complexType/simpleType/element null is returned.

node -
symbolTable -
