Methods
Modifier and Type	Method and Description
`static String`	`getAnnotationDocumentation(Node typeNode)` Returns the complete text of the child xsd:annotation/xsd:documentation element from the provided node.
`static QName`	`getArrayComponentQName(Node node, IntHolder dims, BooleanHolder underlTypeNillable, QNameHolder itemQName, BooleanHolder forElement, SymbolTable symbolTable)` If the specified node represents an array encoding of one of the following forms, then return the qname repesenting the element type of the array.
`static QName`	`getAttributeAnonQName(Node node)` Returns the WSDL2Java QName for the anonymous type of the attribute or null.
`static TypeEntry`	`getBaseType(TypeEntry type, SymbolTable symbolTable)` Returns the base type of a given type with its symbol table.
`static QName`	`getCollectionComponentQName(Node node, QNameHolder itemQName, BooleanHolder forElement, SymbolTable symbolTable)` If the specified node represents an element that references a collection then return the qname repesenting the component of the collection.
`static TypeEntry`	`getComplexElementExtensionBase(Node node, SymbolTable symbolTable)` If the specified node represents a supported JAX-RPC complexType/element which extends another complexType.
`static TypeEntry`	`getComplexElementRestrictionBase(Node node, SymbolTable symbolTable)` Look for the base type of node iff node is a complex type that has been derived by restriction; otherwise return null.
`static Vector`	`getContainedAttributeTypes(Node node, SymbolTable symbolTable)` Return the attribute names and types if any in the node The even indices are the attribute types (TypeEntry) and the odd indices are the corresponding names (Strings).
`static Vector`	`getContainedElementDeclarations(Node node, SymbolTable symbolTable)` If the specified node represents a supported JAX-RPC complexType or simpleType, a Vector is returned which contains ElementDecls for the child element names.

`static boolean`	`isListWithItemType(Node node)` Returns whether the specified node represents a with a nested	`static boolean`	`isMixed(Node node)` This method checks mixed=true attribute is set either on complexType or complexContent element.
`static boolean`	`isSimpleSchemaType(QName qname)` Determine if a QName is a simple XML Schema type
`static boolean`	`isSimpleTypeOrSimpleContent(Node node)` If the specified node is a simple type or contains simpleContent, return true
`static boolean`	`isSimpleTypeWithUnion(Node node)`
`static boolean`	`isWrappedType(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.

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

```
  - getListNode
```

```
  - isSimpleTypeWithUnion
```
public static boolean isSimpleTypeWithUnion(Node node)
```
  - isWrappedType
```
public static boolean isWrappedType(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 Vector getContainedElementDeclarations(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.
    
    Parameters:
    node -

    Returns all textual nodes of a subnode defined by a parent node and a path of element names to that subnode.
    
    Parameters:
