public boolean containsModifiableAliasOf(Store<?> store,
                                         FlowExpressions.Receiver other)

Description copied from class: FlowExpressions.Receiver

Returns true if and only if other appears anywhere in this receiver or an expression appears in this receiver such that other might alias this expression, and that expression is modifiable.

This is always true, except for cases where the Java type information prevents aliasing and none of the subexpressions can alias 'other'.

Overrides:

containsOfClass

public boolean containsOfClass(Class<? extends FlowExpressions.Receiver> clazz)

Specified by:

containsOfClass in class FlowExpressions.Receiver

isUnmodifiableByOtherCode

public boolean isUnmodifiableByOtherCode()

Description copied from class: FlowExpressions.Receiver

Returns true if and only if the value this expression stands for cannot be changed by a method call. This is the case for local variables, the self reference as well as final field accesses for whose receiver FlowExpressions.Receiver.isUnmodifiableByOtherCode() is true.
