Constructor Details

ConstantDynamic

public ConstantDynamic(ConstantDynamic c)

Initialize from another object.

Parameters:

c - Source to copy.

ConstantDynamic

public ConstantDynamic(int bootstrapMethodAttrIndex,
 int nameAndTypeIndex)

Constructs a ConstantDynamic.

Parameters:

bootstrapMethodAttrIndex - Index to the bootstrap method.

nameAndTypeIndex - Index to the name and type.

Method Details

accept

public void accept(Visitor v)

Called by objects that are traversing the nodes of the tree implicitly defined by the contents of a Java class. That is, the hierarchy of methods, fields, attributes, and other elements forms a tree of objects.

Specified by:

accept in interface Node

Specified by:

accept in class Constant

Parameters:

v - Visitor object.

getBootstrapMethodAttrIndex

public int getBootstrapMethodAttrIndex()

Gets the reference (index) to bootstrap method this constant refers to.

Returns:

Reference (index) to bootstrap method this constant refers to. Note that this method is a functional duplicate of getClassIndex for use by ConstantInvokeDynamic.

Since:

6.0

toString

public String toString()

Overrides:

toString in class ConstantCP

Returns:

String representation.
