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

- setInternal
  
  public final 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
- 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
- getType
  
  public Class<? extends 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 boolean isNonNull()
  
  Description copied from interface: ObjectLocation
  
  If true, this location does not accept null values.
  
  Specified by:
  
  isNonNull in interface ObjectLocation
- objectFieldCount
  
  public int objectFieldCount()
  
  Description copied from class: LocationImpl
  
  Get the number of in-object Object fields this location requires.
