Constructor Detail

ModuleMainClass

public ModuleMainClass(int nameIndex,
                       int length,
                       int mainClassIndex,
                       ConstantPool constantPool)

Constructs a new ModuleMainClass.

Parameters:

nameIndex - Index in constant pool.

length - Content length in bytes.

mainClassIndex - Host class index.

constantPool - Array of constants.

ModuleMainClass

public ModuleMainClass(ModuleMainClass c)

Initialize 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 Detail

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)

Description copied from class: Attribute

Creates a deep copy of this attribute.

Specified by:

copy in class Attribute

Parameters:

constantPool - constant pool to save.

Returns:

deep copy of this attribute.

dump

public void dump(java.io.DataOutputStream file)
          throws java.io.IOException

Dumps ModuleMainClass attribute to file stream in binary format.

Overrides:

dump in class Attribute

Parameters:

file - Output file stream.

Throws:

java.io.IOException - Thrown if an I/O error occurs.

getHostClassIndex

public int getHostClassIndex()

Gets the host class index.

Returns:

index into constant pool of host class name.

setHostClassIndex

public void setHostClassIndex(int mainClassIndex)

Sets the host class index.

Parameters:

mainClassIndex - The host class index.

toString

public java.lang.String toString()

Overrides:

toString in class Attribute

Returns:

String representation.
