Constructor Details

NestHost

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

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.

Parameters:

c - Source to copy.

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. I.e., the hierarchy of methods, fields, attributes, etc. spawns 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)

Specified by:

copy in class Attribute

Parameters:

constantPool - constant pool to save.

Returns:

deep copy of this attribute

dump

public void dump(DataOutputStream file)
          throws IOException

Dumps NestHost attribute to file stream in binary format.

Overrides:

dump in class Attribute

Parameters:

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

toString

public String toString()

Overrides:

toString in class Attribute

Returns:

String representation
