Constructor Detail

DeclaredDualLocation

public DeclaredDualLocation(LocationImpl.InternalLongLocation primitiveLocation,
                            ObjectLocation objectLocation,
                            java.lang.Object defaultValue,
                            LayoutImpl layout)

Method Detail

get

public 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 Locations.DualLocation

condition - the result of a shape check or false

See Also:

BaseLocation.get(DynamicObject, Shape)

setInternal

public 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.

Overrides:

setInternal in class Locations.DualLocation

Throws:

IncompatibleLocationException - if value is of non-assignable type

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class Locations.DualLocation

hashCode

public int hashCode()

Overrides:

hashCode in class Locations.DualLocation

changeType

public Locations.DualLocation changeType(java.lang.Class<?> newType)

Overrides:

changeType in class Locations.DualLocation

canStore

public boolean canStore(java.lang.Object value)

Description copied from class: Location

Returns true if the location is compatible with the value. The value may still be rejected if Location.canSet(DynamicObject, Object) returns false.

Overrides:

canStore in class Locations.DualLocation

Parameters:

value - the value in question

toString

public java.lang.String toString()

Overrides:

toString in class Locations.DualLocation
