|Modifier and Type||Method and Description|
This method is called whenever it has been determined that a validating class is to be injected into an injection point, or when a descriptor is being looked up explicitly with the API, or a descriptor is being bound or unbound into the registry.
boolean validate(ValidationInformation info)
The candidate descriptor being passed in may not have yet been reified. If possible, this method should do its work without reifying the descriptor. However, if it is necessary to reify the descriptor, it should be done with the ServiceLocator.reifyDescriptor method.
The operation will determine what operation is being performed. In the
BIND or UNBIND cases the Injectee will be null. In the LOOKUP case
the Injectee will be non-null if this is being done as part of an
injection point. In the LOOKUP case the Injectee will be null if this
is being looked up directly from the
ServiceLocator API, in which
case the caller of the lookup method will be on the call frame.
info- Information about the operation being performed
RuntimeException- This method should not throw an exception. If it does the
ErrorServicewill be called with the
ErrorType.VALIDATE_FAILURE. Even if the
ErrorService.onFailure(ErrorInformation)rethrows the exception that exception will not be thrown up the stack, instead the system will always behave as if false had been returned from this method
