javaLangInvokeMethodHandleClass

public Clazz javaLangInvokeMethodHandleClass

An extra field pointing to the java.lang.invoke.MethodHandle Clazz object. This field is typically filled out by the ClassReferenceInitializer.

Constructor Details

MethodHandleConstant

public MethodHandleConstant()

Creates an uninitialized MethodHandleConstant.

MethodHandleConstant

public MethodHandleConstant(int u1referenceKind,
 int u2referenceIndex)

Creates a new MethodHandleConstant with the given type and method ref index.

Parameters:

u1referenceKind - the reference kind.

u2referenceIndex - the index of the field ref constant, interface method ref constant, or method ref constant in the constant pool.

Method Details

getReferenceKind

public int getReferenceKind()

Returns the kind of reference to which this constant is pointing.

Returns:

One of REF_GET_FIELD, REF_GET_STATIC, REF_PUT_FIELD, REF_PUT_STATIC, REF_INVOKE_VIRTUAL, REF_INVOKE_STATIC, REF_INVOKE_SPECIAL, REF_NEW_INVOKE_SPECIAL, or REF_INVOKE_INTERFACE.

getReferenceIndex

public int getReferenceIndex()

Returns the field ref, interface method ref, or method ref index.

getClassName

public String getClassName(Clazz clazz)

Returns the class name.

getName

public String getName(Clazz clazz)

Returns the method/field name.

getType

public String getType(Clazz clazz)

Returns the type.

referenceAccept

public void referenceAccept(Clazz clazz,
 ConstantVisitor constantVisitor)

Applies the given constant pool visitor to the reference.

getTag

public int getTag()

Description copied from class: Constant

Returns the constant pool info tag that specifies the entry type.

Specified by:

getTag in class Constant

isCategory2

public boolean isCategory2()

Description copied from class: Constant
