Constructor Details

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.

ModuleMainClass

public ModuleMainClass(int name_index,
 int length,
 int main_class_index,
 ConstantPool constant_pool)

Parameters:

name_index - Index in constant pool

length - Content length in bytes

main_class_index - Host class index

constant_pool - Array of constants

ModuleMainClass

ModuleMainClass(int name_index,
 int length,
 DataInput input,
 ConstantPool constant_pool)
         throws IOException

Construct object from input stream.

Parameters:

name_index - Index in constant pool

length - Content length in bytes

input - Input stream

constant_pool - Array of constants

Throws:

IOException

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

dump

public void dump(DataOutputStream file)
          throws IOException

Dump ModuleMainClass 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 main_class_index)

Parameters:

main_class_index - the host class index

toString

public String toString()

Overrides:

toString in class Attribute

Returns:

String representation

copy

public Attribute copy(ConstantPool _constant_pool)

Specified by:

copy in class Attribute

Returns:

deep copy of this attribute
