Method Details

make

public static ElementType make(String namespaceURI,
 String localName)

An element type for match by name.

Parameters:

namespaceURI - full name of namespace, or null for any namespace.

localName - if null matches any local name; otherwise must be intered, and matches by identity.

make

public static ElementType make(Symbol qname)

getImplementationType

public Type getImplementationType()

Description copied from class: Type

Return Java-level implementation type. The type used to implement types not natively understood by the JVM or the Java language. Usually, the identity function. However, a language might handle union types or template types or type expressions calculated at run time. In that case return the type used at the Java level, and known at compile time.

Specified by:

getImplementationType in interface TypeValue

Overrides:

getImplementationType in class NodeType

getNamespaceURI

public final String getNamespaceURI()

getLocalName

public final String getLocalName()

emitCoerceFromObject

public void emitCoerceFromObject(CodeAttr code)

Description copied from class: ObjectType

Compile (in given method) cast from Object to this Type.

Overrides:

emitCoerceFromObject in class NodeType

coerceFromObject

public Object coerceFromObject(Object obj)

Description copied from class: Type

Convert an object to a value of this Type. The result is actually of the implementation type, boxed as appropriate, so it is suitable for standard reflective operations, like the arguments to Field#set or Method#invoke. Throw a ClassCastException when this is not possible.

Overrides:

coerceFromObject in class NodeType

isInstancePos

public boolean isInstancePos(AbstractSequence seq,
 int ipos)

Specified by:

isInstancePos in interface ItemPredicate

Overrides:

isInstancePos in class NodeType

isInstance

public boolean isInstance(AbstractSequence seq,
 int ipos,
 Object elementType)

Specified by:

isInstance in interface ElementPredicate

isInstance

public boolean isInstance(Object obj)

Overrides:

isInstance in class NodeType

coerceOrNull

public static KElement coerceOrNull(Object obj,
 String namespaceURI,
 String localName)

coerce

public static KElement coerce(Object obj,
 String namespaceURI,
 String localName)

emitCoerceOrNullMethod

protected void emitCoerceOrNullMethod(Variable incoming,
 Compilation comp)

Overrides:

emitCoerceOrNullMethod in class NodeType

getNamespaceNodes

public NamespaceBinding getNamespaceNodes()

setNamespaceNodes

public void setNamespaceNodes(NamespaceBinding bindings)

getConstructor

public Procedure getConstructor()

Description copied from interface: TypeValue

Get the constructor function for this type. Returns null if there is no contructor function. Also returns null if this extends ClassType or ArrayType and standard Java constructors (<init> methods) should be used.

Specified by:

getConstructor in interface TypeValue

Overrides:

getConstructor in class NodeType

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Overrides:

writeExternal in class NodeType

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
ClassNotFoundException

Specified by:

readExternal in interface Externalizable

Overrides:

readExternal in class NodeType

Throws:

IOException

ClassNotFoundException

toString

public String toString()

Overrides:

toString in class NodeType
