Method Summary

Modifier and Type	Method	Description
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 one.
boolean	equalsInstruction(Instruction other)	Two local variable instructions are equal if the local index they reference is equal or if either index is 0/unset.
(package private) int	getLength()	Return the length in bytes of this opcode, including all arguments.
(package private) void	read(DataInput in)	Read the arguments for this opcode from the given stream.
(package private) void	write(DataOutput out)	Write the arguments for this opcode to the given stream.

Method Details

getLength

int getLength()

Description copied from class: Instruction

Return the length in bytes of this opcode, including all arguments. For many opcodes this method relies on an up-to-date byte index.

Overrides:

getLength in class Instruction

equalsInstruction

public boolean equalsInstruction(Instruction 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:

equalsInstruction in class LocalVariableInstruction

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 one.

Specified by:

acceptVisit in interface VisitAcceptor

Overrides:

acceptVisit in class Instruction

read

void read(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:

read in class Instruction

Throws:

IOException

write

void write(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:

write in class Instruction

Throws:

IOException
