Method Summary
static StringgenQNameAttributeString(QName qname, String prefix)
Generate an XML prefixed attribute value with a corresponding xmlns declaration for the prefix.
static StringgenQNameAttributeStringWithLastLocalPart(QName qname, String prefix)
static StringgetAttribute(Node node, String attr)
Given a node, return the value of the given attribute.
static VectorgetAttributesWithLocalName(Node node, String localName)
Given a node, return the attributes that have the specified local name.
static HashSetgetDerivedTypes(TypeEntry type, SymbolTable symbolTable)
This method returns a set of all types that are derived from this type via an extension of a complexType
static StringgetLastLocalPart(String localPart)
static QName[]getMemberTypeQNames(Node node)
Method getMemberTypeQNames
protected static HashSetgetNestedTypes(TypeEntry type, SymbolTable symbolTable, boolean derivedFlag)
This method returns a set of all the nested types.
static QNamegetNodeNameQName(Node node)
XML nodes may have a name attribute.
static QNamegetNodeQName(Node node)
An xml element may have a name.
static QNamegetQNameFromPrefixedName(Node node, String prefixedName)
Convert a prefixed name into a qname
static StringgetScopedAttribute(Node node, String attr)
Given a node, return the value of the given attribute.
static QNamegetTypeQName(Node node, BooleanHolder forElement, boolean ignoreMaxOccurs)
An XML element or attribute node has several ways of identifying the type of the element or attribute: - use the type attribute to reference a complexType/simpleType - use the ref attribute to reference another element, group or attributeGroup - use of an anonymous type (i.e. a nested type underneath itself) - a wsdl:part can use the element attribute.

Method Detail

genQNameAttributeString

public static String genQNameAttributeString(QName qname, String prefix)
Generate an XML prefixed attribute value with a corresponding xmlns declaration for the prefix. If there is no namespace, don't prefix the name or emit the xmlns attribute.

Caller should provide the enclosing quotes.

Usage: println("name=\"" + genXMLQNameString(qname, "foo") + "\""

Parameters: qname prefix

Returns:

genQNameAttributeStringWithLastLocalPart

public static String genQNameAttributeStringWithLastLocalPart(QName qname, String prefix)

getAttribute

public static String getAttribute(Node node, String attr)
Given a node, return the value of the given attribute. Returns null if the attribute is not found

Parameters: node attr

Returns:

getAttributesWithLocalName

public static Vector getAttributesWithLocalName(Node node, String localName)
Given a node, return the attributes that have the specified local name. Returns null if the attribute is not found

Parameters: node localName

Returns:

getDerivedTypes

public static HashSet getDerivedTypes(TypeEntry type, SymbolTable symbolTable)
This method returns a set of all types that are derived from this type via an extension of a complexType

Parameters: type symbolTable

Returns:

getLastLocalPart

public static String getLastLocalPart(String localPart)

getMemberTypeQNames

public static QName[] getMemberTypeQNames(Node node)
Method getMemberTypeQNames

Parameters: node

Returns:

getNestedTypes

protected static HashSet getNestedTypes(TypeEntry type, SymbolTable symbolTable, boolean derivedFlag)
This method returns a set of all the nested types. Nested types are types declared within this TypeEntry (or descendents) plus any extended types and the extended type nested types The elements of the returned HashSet are Types.

Parameters: type is the type entry to consider symbolTable is the symbolTable derivedFlag should be set if all dependendent derived types should also be returned.

Returns:

getNodeNameQName

public static QName getNodeNameQName(Node node)
XML nodes may have a name attribute. For example <.element name="foo" type="b:bar">. has the name attribute value "foo". This routine gets the QName of the name attribute value.

Parameters: node

Returns:

getNodeQName

public static QName getNodeQName(Node node)
An xml element may have a name. For example <.element name="foo" type="b:bar">. has the name "element". This routine gets the full QName of the element.

Parameters: node

Returns:

getQNameFromPrefixedName

public static QName getQNameFromPrefixedName(Node node, String prefixedName)
Convert a prefixed name into a qname

Parameters: node prefixedName

Returns:

getScopedAttribute

public static String getScopedAttribute(Node node, String attr)
Given a node, return the value of the given attribute. If the attribute does not exist, searching continues through ancestor nodes until found. This method is useful for finding attributes that pertain to a group of contained nodes (i.e. xlmns, xmlns:tns, targetNamespace, name)

Parameters: node attr

Returns:

getTypeQName

public static QName getTypeQName(Node node, BooleanHolder forElement, boolean ignoreMaxOccurs)
An XML element or attribute node has several ways of identifying the type of the element or attribute: - use the type attribute to reference a complexType/simpleType - use the ref attribute to reference another element, group or attributeGroup - use of an anonymous type (i.e. a nested type underneath itself) - a wsdl:part can use the element attribute. - an extension can use the base attribute.

This routine returns a QName representing this "type". The forElement value is also returned to indicate whether the QName represents an element (i.e. obtained using the ref attribute) or a type.

Other attributes affect the QName that is returned. If the "minOccurs" and "maxOccurs" are set such that the type is a collection of "types", then an artificial qname is returned to represent the collection.

Parameters: node of the reference forElement output parameter is set to true if QName is for an element (i.e. ref= or element= attribute was used). ignoreMaxOccurs indicates whether minOccurs/maxOccurs affects the QName

Returns: QName representing the type of this element
