Constructor Detail

BasicLocations.ObjectArrayLocation

public BasicLocations.ObjectArrayLocation(int index,
                                  Location arrayLocation)

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 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

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

getType

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

Description copied from interface: TypedLocation

The type of this location.

Specified by:

getType in interface ObjectLocation

Specified by:

getType in interface TypedLocation

isNonNull

public final boolean isNonNull()

Description copied from interface: ObjectLocation

If true, this location does not accept null values.

Specified by:

isNonNull in interface ObjectLocation

objectArrayCount

public int objectArrayCount()

Description copied from class: LocationImpl

Get the number of object array elements this location requires.

Overrides:

objectArrayCount in class LocationImpl
