Constructor Detail

StackMap

public StackMap(int name_index, int length, StackMapEntry[] map, ConstantPool constant_pool)

StackMap

StackMap(int name_index, int length, DataInputStream file, ConstantPool constant_pool)

Construct object from file stream.

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.

Parameters: v Visitor object

copy

public Attribute copy(ConstantPool _constant_pool)

Returns: deep copy of this attribute

dump

public final void dump(DataOutputStream file)

Dump line number table attribute to file stream in binary format.

Parameters: file Output file stream

Throws: IOException
