NestMembersback to summary
pack-priv NestMembers(final int nameIndex, final int length, final DataInput input, final ConstantPool constantPool) throws IOException

Constructs object from input stream.

Parameters
nameIndex:int

Index in constant pool

length:int

Content length in bytes

input:DataInput

Input stream

constantPool:ConstantPool

Array of constants

Exceptions
IOException:
if an I/O error occurs.
NestMembersback to summary
public NestMembers(final int nameIndex, final int length, final int[] classes, final ConstantPool constantPool)
Parameters
nameIndex:int

Index in constant pool

length:int

Content length in bytes

classes:int[]

Table of indices in constant pool

constantPool:ConstantPool

Array of constants

NestMembersback to summary
public NestMembers(final NestMembers c)

Initialize from another object. Note that both objects use the same references (shallow copy). Use copy() for a physical copy.

Parameters
c:NestMembers

Source to copy.

Method Detail

acceptback to summary
public void accept(final Visitor v)

Implements abstract com.sun.org.apache.bcel.internal.classfile.Attribute.accept.

Implements com.sun.org.apache.bcel.internal.classfile.Node.accept.

Called by objects that are traversing the nodes of the tree implicitly defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

Parameters
v:Visitor

Visitor object
