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 MultiANewArray instructions are equal if they have the same type and dimensions, or if the type and dimensions of either is unset.
int	getDimensions()	Return the dimensions of the array, or -1 if not set.
int	getStackChange()	Return the number of stack positions this instruction pushes or pops during its execution.
MultiANewArrayInstruction	setDimensions(int dims)	Set the dimensions of the array.

Method Detail

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

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

getDimensions

public int getDimensions()

Return the dimensions of the array, or -1 if not set.

setDimensions

public MultiANewArrayInstruction setDimensions(int dims)

Set the dimensions of the array.

Returns:

this instruction, for method chaining

equalsInstruction

public boolean equalsInstruction(Instruction 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:

equalsInstruction 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 one.

Specified by:

acceptVisit in interface VisitAcceptor

Overrides:

acceptVisit in class ClassInstruction
