equals

public boolean equals(@Nullable Object obj)

Overrides:

equals in class Object

getElement

public Element getElement()

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

containsOfClass

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

Specified by:

containsOfClass in class Receiver

syntacticEquals

public boolean syntacticEquals(Receiver other)

Description copied from class: Receiver

Returns true if and only if the two receivers are syntactically identical.

Overrides:

syntacticEquals in class Receiver

Parameters:

other - the other object to compare to this one

Returns:

true if and only if the two receivers are syntactically identical

containsSyntacticEqualReceiver

public boolean containsSyntacticEqualReceiver(Receiver other)

Description copied from class: Receiver

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

Overrides:

containsSyntacticEqualReceiver in class 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: 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, final field accesses whose receiver is Receiver.isUnassignableByOtherCode(), and binary operations whose left and right operands are both Receiver.isUnmodifiableByOtherCode().

Specified by:

isUnassignableByOtherCode in class Receiver

See Also:

Receiver.isUnmodifiableByOtherCode()

isUnmodifiableByOtherCode

public boolean isUnmodifiableByOtherCode()

Description copied from class: 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 Receiver.isUnassignableByOtherCode() and its type is immutable.

Specified by:

isUnmodifiableByOtherCode in class Receiver
