NestHost

public NestHost(NestHost c)

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

public NestHost(int nameIndex,
 int length,
 int hostClassIndex,
 ConstantPool constantPool)

Parameters:

nameIndex - Index in constant pool

length - Content length in bytes

hostClassIndex - Host class index

constantPool - Array of constants

Method Details

accept

public void accept(Visitor v)

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

Specified by:

file - Output file stream

Throws:

IOException - if an I/O error occurs.

getHostClassIndex

public int getHostClassIndex()

Returns:

index into constant pool of host class name.

setHostClassIndex

public void setHostClassIndex(int hostClassIndex)

Parameters:

hostClassIndex - the host class index
