org.glassfish.hk2.utilities.general.internal.MessageInterpolatorImpl

All Implemented Interfaces:

jakarta.validation.MessageInterpolator

public class MessageInterpolatorImpl
extends Object
implements jakarta.validation.MessageInterpolator

Custom MessageInterpolatorImpl for HK2

This message interpolator is different from the default one in the following ways:

1. It uses a class specified in the "payload" argument to the annotation to find the class loader to find the resource bundle for messages. This allows classes that are in OSGi modules to specify a resource bundle for bean validation messages.
2. The "LocalStrings" resource bundle within the same package as the payload class is used to search for messages. If a message is not found, the message is obtained from the default bean validation resource bundle.

This class borrows heavily from the RI implementation of the ResourcBundleMessageInterpolator authored by Emmanuel Bernard, Hardy Ferentschik, and Gunnar Morling.

interpolate

public String interpolate(String message,
 jakarta.validation.MessageInterpolator.Context context)

Specified by:

interpolate in interface jakarta.validation.MessageInterpolator

interpolate

public String interpolate(String message,
 jakarta.validation.MessageInterpolator.Context context,
 Locale locale)

Runs the message interpolation according to algorithm specified in JSR 303.
Note:
Look-ups in user bundles is recursive whereas look-ups in default bundle are not!

Specified by:

interpolate in interface jakarta.validation.MessageInterpolator

Parameters:

message - the message to interpolate

context - the context of the annotation which holds the parameters for which to interpolate this message

locale - the Locale to use for the resource bundle.

Returns:

the interpolated message.
