DualLocation

public DualLocation(LocationImpl.InternalLongLocation primitiveLocation,
                    ObjectLocation objectLocation,
                    LayoutImpl layout)

DualLocation

public DualLocation(LocationImpl.InternalLongLocation primitiveLocation,
                    ObjectLocation objectLocation,
                    LayoutImpl layout,
                    java.lang.Class<?> type)

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 Location

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.

Specified by:

setInternal in class LocationImpl

Throws:

IncompatibleLocationException - if value is of non-assignable type

primitiveFieldCount

public int primitiveFieldCount()

Description copied from class: LocationImpl

Get the number of in-object primitive fields this location requires.

Overrides:

primitiveFieldCount in class LocationImpl

primitiveArrayCount

public int primitiveArrayCount()

Description copied from class: LocationImpl

Get the number of primitive array elements this location requires.

Overrides:

primitiveArrayCount in class LocationImpl

objectFieldCount

public int objectFieldCount()

Description copied from class: LocationImpl

Get the number of in-object Object fields this location requires.

Overrides:

objectFieldCount in class LocationImpl

objectArrayCount

public int objectArrayCount()

Description copied from class: LocationImpl

Get the number of object array elements this location requires.

Overrides:

objectArrayCount in class LocationImpl

toString

public java.lang.String toString()

Overrides:

toString in class LocationImpl

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class LocationImpl

hashCode

public int hashCode()

Overrides:

hashCode in class LocationImpl

getObjectLocation

public ObjectLocation getObjectLocation()

changeType

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

getType

public java.lang.Class<?> getType()

Description copied from interface: TypedLocation

The type of this location.

Specified by:

getType in interface TypedLocation

isNonNull

public boolean isNonNull()

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 LocationImpl

Parameters:

value - the value in question
