equals

public boolean equals(Object o)

Overrides:

equals in class UnarySideEffect

getField

protected IField getField()

isLoadOperator

protected boolean isLoadOperator()

Description copied from class: UnarySideEffect

A "load" operator generates defs of the fixed set. A "store" operator generates uses of the fixed set.

Specified by:

isLoadOperator in class UnarySideEffect

isComplex

public boolean isComplex()

Description copied from interface: IPointerOperator

Is the operator complex; i.e., might it give rise to new constraints?

Specified by:

isComplex in interface IPointerOperator
