  org.apache.bcel.verifier.statics.LocalVariableInfo

---

public class LocalVariableInfo

extends java.lang.Object

A utility class holding the information about the name and the type of a local variable in a given slot (== index). This information often changes in course of byte code offsets.

Method Detail

setName

private void setName(int offset,
                     java.lang.String name)

Adds a name of a local variable and a certain slot to our 'names' (Hashtable) database.

---

setType

private void setType(int offset,
                     org.apache.bcel.generic.Type t)

Adds a type of a local variable and a certain slot to our 'types' (Hashtable) database.

---

getType

public org.apache.bcel.generic.Type getType(int offset)

Returns the type of the local variable that uses this local variable slot at the given bytecode offset. Care for legal bytecode offsets yourself, otherwise the return value might be wrong. May return 'null' if nothing is known about the type of this local variable slot at the given bytecode offset.

---

getName

public java.lang.String getName(int offset)

Returns the name of the local variable that uses this local variable slot at the given bytecode offset. Care for legal bytecode offsets yourself, otherwise the return value might be wrong. May return 'null' if nothing is known about the type of this local variable slot at the given bytecode offset.

---

add

public void add(java.lang.String name,
                int startpc,
                int length,
                org.apache.bcel.generic.Type t)
         throws org.apache.bcel.verifier.exc.LocalVariableInfoInconsistentException

Adds some information about this local variable (slot).

---

add

private void add(int offset,
                 java.lang.String name,
                 org.apache.bcel.generic.Type t)
          throws org.apache.bcel.verifier.exc.LocalVariableInfoInconsistentException
