Constructor Detail

JavaExternalObjectType

public JavaExternalObjectType(Configuration config,
                              java.lang.Class<?> javaClass)

Create an external object type.

Parameters:

javaClass - the Java class to which this type corresponds

Method Detail

getConfiguration

public Configuration getConfiguration()

getName

public java.lang.String getName()

Get the local name of this type.

Specified by:

getName in class ExternalObjectType

Returns:

the fully qualified name of the Java class.

getTargetNamespace

public java.lang.String getTargetNamespace()

Get the target namespace of this type. The is always NamespaceConstant.JAVA_TYPE.

Specified by:

getTargetNamespace in class ExternalObjectType

Returns:

the target namespace of this type definition.

getTypeName

public StructuredQName getTypeName()

Get the name of this type as a StructuredQName, unless the type is anonymous, in which case return null

Specified by:

getTypeName in class ExternalObjectType

Returns:

the name of the atomic type, or null if the type is anonymous.

getPrimitiveItemType

public ItemType getPrimitiveItemType()

Get the primitive item type corresponding to this item type.

Specified by:

getPrimitiveItemType in interface ItemType

Overrides:

getPrimitiveItemType in class AnyExternalObjectType

Returns:

EXTERNAL_OBJECT_TYPE, the ExternalObjectType that encapsulates the Java type Object.class.

getRelationship

public int getRelationship(JavaExternalObjectType other)

Get the relationship of this external object type to another external object type

Parameters:

other - the other external object type

Returns:

the relationship of this external object type to another external object type, as one of the constants in class TypeHierarchy, for example TypeHierarchy.SUBSUMES

getJavaClass

public java.lang.Class<?> getJavaClass()

Get the Java class to which this external object type corresponds

Returns:

the corresponding Java class

matches

public boolean matches(Item item,
                       TypeHierarchy th)

Test whether a given item conforms to this type

Specified by:

matches in interface ItemType

Overrides:

matches in class AnyExternalObjectType

Parameters:

item - The item to be tested

th - The type hierarchy cache

Returns:

true if the item is an instance of this type; false otherwise

toString

public java.lang.String toString()

Specified by:

toString in interface ItemType

Overrides:

toString in class java.lang.Object

getDisplayName

public java.lang.String getDisplayName()

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Test whether two ExternalObjectType objects represent the same type

Overrides:

equals in class java.lang.Object

Parameters:

obj - the other ExternalObjectType

Returns:

true if the two objects represent the same type

classNameToLocalName

public static java.lang.String classNameToLocalName(java.lang.String className)

Static method to convert a Java class name to an XPath local name. This involves the following substitutions: "$" is replaced by "-", and "[" is replaced by "_-".

localNameToClassName

public static java.lang.String localNameToClassName(java.lang.String className)

Static method to convert an XPath local name to a Java class name. This involves the following substitutions: "-" is replaced by "$", and leading "_-" pairs are replaced by "[".

classNameToQName

public static StructuredQName classNameToQName(java.lang.String className)

Static method to get the QName corresponding to a Java class name
