Method Detail

isSecondClassMutableType

public static boolean isSecondClassMutableType(java.lang.Class c)

Tests whether a given type represents a supported second-class mutable type.

Parameters:

c - The class to be tested.

Returns:

true if fields declared as type c are supported as second-class mutable objects, false otherwise.

forFieldType

public static SCOProcessor forFieldType(java.lang.Class c)

Returns the SCO processor for fields of the given type.

Parameters:

c - The type of field.

Returns:

The corresponding SCO processor.

newSCOInstance

public abstract SCO newSCOInstance(java.lang.Object owner,
                                   java.lang.String fieldName,
                                   java.lang.Object value)

Returns a new SCO instance. The returned instance is owned by the specified owner but has not been assigned to the corresponding field.

Parameters:

owner - The first-class object that will own the new second-class object.

fieldName - The name of the field in the owning object.

value - The initial value of the new object.

Returns:

A new SCO instance.
