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.
protected void	copy(Instruction orig)
boolean	equals(Object other) Two MULTIANEWARRAY instructions are equal if they have the same type and dimensions, or if the type and dimensions of either is unset.
int	getDimensions() Get the dimensions of the array.
int	getLength() Return the length in bytes of this opcode, including all arguments.
int	getStackChange() Return the number of stack positions this instruction pushes or pops during its execution.
protected void	readData(DataInput in) Read the arguments for this opcode from the given stream.
MultiANewArrayInstruction	setDimensions(int dims) Set the dimensions of the array.
protected void	writeData(DataOutput out) Write the arguments for this opcode to the given stream.

Method Detail

setDimensions

public MultiANewArrayInstruction setDimensions(int dims)

Set the dimensions of the array.

Returns:

this Instruction, for method chaining

getDimensions

public int getDimensions()

Get the dimensions of the array.

equals

public boolean equals(Object other)

Two MULTIANEWARRAY instructions are equal if they have the same type and dimensions, or if the type and dimensions of either is unset.

Overrides:

equals in class ClassInstruction

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 ClassInstruction

getStackChange

public int getStackChange()

Description copied from class: Instruction

Return the number of stack positions this instruction pushes or pops during its execution.

Overrides:

getStackChange in class ClassInstruction

Tags copied from class: Instruction

Returns:

0 if the stack is not affected by this instruction, a positive number if it pushes onto the stack, and a negative number if it pops from the stack

copy

protected void copy(Instruction orig)

Overrides:

copy in class ClassInstruction

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 ClassInstruction

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 ClassInstruction

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 ClassInstruction
