All Implemented Interfaces:

Cloneable, Node

public final class Record
extends Attribute

Extends Attribute and records the classes and interfaces that are authorized to claim membership in the nest hosted by the current class or interface. There may be at most one Record attribute in a ClassFile structure.

Constructor Details

Record

public Record(int nameIndex,
 int length,
 RecordComponentInfo[] classes,
 ConstantPool constantPool)

Constructs a new instance using components.

Parameters:

nameIndex - Index in constant pool.

length - Content length in bytes.

classes - Array of Record Component Info elements.

constantPool - Array of constants.

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. For example, 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 Attribute

Parameters:

v - Visitor object.

copy

public Attribute copy(ConstantPool constantPool)

Copies this instance and its components.

Specified by:

copy in class Attribute

Parameters:

constantPool - constant pool to save.

Returns:

A deep copy of this instance and its components.

dump

public void dump(DataOutputStream file)
          throws IOException

Dumps this instance into a file stream in binary format.

Overrides:

dump in class Attribute

Parameters:

file - output stream.

Throws:

IOException - Thrown if an I/O error occurs.

getComponents

public RecordComponentInfo[] getComponents()

Gets all the record components.

Returns:

array of Record Component Info elements.

toString

public String toString()

Converts this instance to a String suitable for debugging.

Overrides:

toString in class Attribute

Returns:

String a String suitable for debugging.
