syntacticEquals

public boolean syntacticEquals(FlowExpressions.Receiver other)

Overrides:

syntacticEquals in class FlowExpressions.Receiver

Returns:

true if and only if the two receiver are syntactically identical

containsSyntacticEqualReceiver

public boolean containsSyntacticEqualReceiver(FlowExpressions.Receiver other)

Overrides:

containsSyntacticEqualReceiver in class FlowExpressions.Receiver

Returns:

true if and only if this receiver contains a receiver that is syntactically equal to other.

isUnassignableByOtherCode

public boolean isUnassignableByOtherCode()

Description copied from class: FlowExpressions.Receiver

Returns true if and only if the value this expression stands for cannot be changed (with respect to ==) 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.isUnassignableByOtherCode() is true.

Specified by:

isUnassignableByOtherCode in class FlowExpressions.Receiver

See Also:

FlowExpressions.Receiver.isUnmodifiableByOtherCode()

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, including changes to any of its fields.

Approximately, this returns true if the expression is FlowExpressions.Receiver.isUnassignableByOtherCode() and its type is immutable.

Specified by:

isUnmodifiableByOtherCode in class FlowExpressions.Receiver
