Constructor Detail

ValueLocation

public ValueLocation(java.lang.Object value)

Method Detail

hashCode

public int hashCode()

Overrides:

hashCode in class LocationImpl

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class LocationImpl

get

public final java.lang.Object get(DynamicObject store,
                                  boolean condition)

Description copied from interface: BaseLocation

Get object value as object at this location in store. For internal use only and subject to change, use BaseLocation.get(DynamicObject, Shape) instead.

Specified by:

get in interface BaseLocation

Overrides:

get in class Location

condition - the result of a shape check or false

See Also:

BaseLocation.get(DynamicObject, Shape)

set

public final void set(DynamicObject store,
                      java.lang.Object value,
                      Shape shape)
               throws IncompatibleLocationException,
                      FinalLocationException

Description copied from interface: BaseLocation

Set object value at this location in store.

Specified by:

set in interface BaseLocation

Overrides:

set in class LocationImpl

shape - the current shape of the storage object

Throws:

IncompatibleLocationException - for storage type invalidations

FinalLocationException - for effectively final fields

canStoreFinal

protected boolean canStoreFinal(DynamicObject store,
                                java.lang.Object val)

Overrides:

canStoreFinal in class LocationImpl

setInternal

public final void setInternal(DynamicObject store,
                              java.lang.Object value)
                       throws IncompatibleLocationException

Description copied from class: Location

Like Location.set(DynamicObject, Object, Shape), but does not invalidate final locations. For internal use only and subject to change, use DynamicObjectFactory to create objects with predefined properties.

Specified by:

setInternal in class LocationImpl

Throws:

IncompatibleLocationException - if value is of non-assignable type

toString

public java.lang.String toString()

Overrides:

toString in class LocationImpl
