Method Detail

validateUpdate

public static <T extends BaseResource> void validateUpdate(String[] strict,
                                           T incoming,
                                           T existing)

Validate update from an immutability point of view.

Type Parameters:

T - representation type

Parameters:

strict - array of strictly immutable field names

incoming - the incoming representation

existing - the existing representation

Throws:

javax.ws.rs.WebApplicationException - wrapping an appropriate response iff an immutability constraint has been broken

imposeConstraints

public static <T extends BaseResource> javax.ws.rs.core.Response imposeConstraints(String[] strict,
                                                                   T incoming,
                                                                   T existing)

Impose immutability constraints.

Type Parameters:

T - representation type

Parameters:

strict - array of strictly immutable field names

incoming - incoming representation

existing - existing representation

Returns:

error Response if appropriate

imposeConstraints

public static <T extends BaseResource> javax.ws.rs.core.Response imposeConstraints(String[] strict,
                                                                   T incoming,
                                                                   T existing,
                                                                   String reason,

Impose immutability constraints.

Type Parameters:

T - representation type

Parameters:

strict - array of strictly immutable field names

incoming - incoming representation

existing - existing representation

reason - the fault reason

detail - the fault detail

Returns:

error Response if appropriate
