Method Detail

get

java.lang.Object get(DynamicObject store,
                   Shape shape)

Get object value as object at this location in store.

Parameters:

shape - the current shape of the object, which must contain this location

get

java.lang.Object get(DynamicObject store,
                   boolean condition)

Get object value as object at this location in store. For internal use only and subject to change, use get(DynamicObject, Shape) instead.

Parameters:

condition - the result of a shape check or false
