Constructor Detail

ArrayAccess

public ArrayAccess(TypeMirror type,
                   FlowExpressions.Receiver receiver,
                   FlowExpressions.Receiver index)

Method Detail

containsOfClass

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

Specified by:

containsOfClass in class FlowExpressions.Receiver

getReceiver

public FlowExpressions.Receiver getReceiver()

getIndex

public FlowExpressions.Receiver getIndex()

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.

Specified by:

isUnmodifiableByOtherCode in class FlowExpressions.Receiver

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.

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

containsModifiableAliasOf

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:

containsModifiableAliasOf in class FlowExpressions.Receiver

equals

public boolean equals(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
