LocalVariableTable

public LocalVariableTable(LocalVariableTable c)

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

LocalVariableTable

public LocalVariableTable(int name_index,
 int length,
 LocalVariable[] local_variable_table,
 ConstantPool constant_pool)

Parameter:

name_index - Index in constant pool to `LocalVariableTable'

length - Content length in bytes

local_variable_table - Table of local variables

constant_pool - Array of constants

Methodendetails

accept

public void accept(ClassVisitor 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.

Parameter:

v - Visitor object

dump

public final void dump(DataOutputStream file)
                throws IOException

Dump local variable table attribute to file stream in binary format.
