Modifier and Type	Method and Description
boolean	containsModifiableAliasOf(Store<?> store, Receiver other) 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.

int	hashCode()
boolean	isUnassignableByOtherCode() Returns true if and only if the value this expression stands for cannot be changed (with respect to ==) by a method call.
boolean	isUnmodifiableByOtherCode() 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.
boolean	syntacticEquals(Receiver other) Returns true if and only if the two receivers are syntactically identical.

Method Detail

equals

public boolean equals(@Nullable Object obj)

Overrides:

equals in class Object

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

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

See Also:

Receiver.isUnassignableByOtherCode()

containsModifiableAliasOf

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

Description copied from class: 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:

containsModifiableAliasOf in class Receiver
