Method Details
- get
  
  public 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, 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 String toString()
  
  Overrides:
  
  toString in class LocationImpl
- equals
  
  public boolean equals(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(Class<?> newType)
- getType
  
  public 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(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
