public static final StackManipulation.Size ZERO

A size of zero.

Constructor Detail

Size

public Size(int sizeImpact,
            int maximalSize)

Creates an immutable descriptor of the size change that is implied by some stack manipulation.

Parameters:

sizeImpact - The change of the size of the operand stack that is implied by some stack manipulation.

maximalSize - The maximal stack size that is required for executing this stack manipulation. Should never be negative number.

Method Detail

getSizeImpact

public int getSizeImpact()

Returns the size change on the operand stack that is represented by this instance.

Returns:

The size change on the operand stack that is represented by this instance.

getMaximalSize

public int getMaximalSize()

Returns the maximal interim size of the operand stack that is represented by this instance.

Returns:

The maximal interim size of the operand stack that is represented by this instance.

aggregate

public StackManipulation.Size aggregate(StackManipulation.Size other)

Concatenates this size representation with another size representation in order to represent the size change that is represented by both alterations of the operand stack size.

Parameters:

other - The other size representation.

Returns:

A new size representation representing both stack size requirements.
