Method Details

of

public static JavaExternalObjectType of(Class<?> javaClass)

Allocate an external object type. for a given Java class. Reuses a known JavaExternalObjectType if found in a static cache

Parameters:

javaClass - the Java class to which this type corresponds

Returns:

the corresponding JavaExternalObjectType

getName

public 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 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 Affinity 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 Affinity, for example Affinity.SUBSUMES

getJavaClass

public 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 String toString()

Overrides:

toString in class ExternalObjectType

getDisplayName

public String getDisplayName()

hashCode

public int hashCode()

Returns a hash code value for the object.

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Test whether two ExternalObjectType objects represent the same type

Overrides:

equals in class Object

Parameters:

obj - the other ExternalObjectType

Returns:

true if the two objects represent the same type

classNameToLocalName

public static String classNameToLocalName(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 String localNameToClassName(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(String className)

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