Method Summary

void	acceptVisit(BCVisitor visit) Accept a visit from a BCVisitor, calling the appropriate methods to notify the visitor that it has entered this entity, and to provide it with the proper callbacks for each sub-entity owned by this object.
boolean	equals(Object other) Two local variable instructions are equal if the local index they reference is equal or if either index is 0/unset.
int	getLength() Return the length in bytes of this opcode, including all arguments.
protected void	readData(DataInput in) Read the arguments for this opcode from the given stream.
protected void	writeData(DataOutput out) Write the arguments for this opcode to the given stream.

Method Detail

equals

public boolean equals(Object other)

Description copied from class: LocalVariableInstruction

Two local variable instructions are equal if the local index they reference is equal or if either index is 0/unset.

Overrides:

equals in class LocalVariableInstruction

getLength

public int getLength()

Description copied from class: Instruction

Return the length in bytes of this opcode, including all arguments. This method should be overridden by opcodes that take arguments.

Overrides:

getLength in class Instruction

readData

protected void readData(DataInput in)
                 throws IOException

Description copied from class: Instruction

Read the arguments for this opcode from the given stream. This method should be overridden by opcodes that take arguments.

Overrides:

readData in class Instruction

writeData

protected void writeData(DataOutput out)
                  throws IOException

Description copied from class: Instruction

Write the arguments for this opcode to the given stream. This method should be overridden by opcodes that take arguments.

Overrides:

writeData in class Instruction

acceptVisit

public void acceptVisit(BCVisitor visit)

Description copied from interface: VisitAcceptor

Accept a visit from a BCVisitor, calling the appropriate methods to notify the visitor that it has entered this entity, and to provide it with the proper callbacks for each sub-entity owned by this object.

Overrides:

acceptVisit in class Instruction
