clone, equals, finalize, getClass, hashCode, notify, notifyAll, wait, wait, wait
LocalVariable
public LocalVariable (LocalVariable c)
Initialize from another object. Note that both objects use the same
references (shallow copy). Use copy() for a physical copy.
LocalVariable
public LocalVariable (int start_pc,
int length,
int name_index,
int signature_index,
int index,
ConstantPool constant_pool)
Parameters: start_pc - Range in which the variablelength - ... is validname_index - Index in constant pool of variable namesignature_index - Index of variable's signatureindex - Variable is `index'th local variable on the method's frameconstant_pool - Array of constants
accept
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.
Specified by: accept Node
Parameters: v - Visitor object
dump
public final void dump (java.io.DataOutputStream file)
throws java.io.IOException
Dump local variable to file stream in binary format.
Parameters: file - Output file stream

setStartPC
public final void setStartPC (int start_pc)
Parameters: start_pc - Specify range where the local variable is valid.
toString
public final java.lang.String toString ()
Overrides: toString in class java.lang.Object
Returns: string representation.
