Method Summary
Modifier and TypeMethodDescriptionifSupported(SearchPredicateFactoryExtension<T> extension, Function<T, ? extends PredicateFinalStep> predicateContributor) If the given extension is supported, and none of the previous extensions passed toSearchPredicateFactoryExtensionIfSupportedStep.ifSupported(SearchPredicateFactoryExtension, Function)was supported, extend the current factory with this extension, apply the given function to the extended factory, and store the resulting predicate for later retrieval.orElse(Function<SearchPredicateFactory, ? extends PredicateFinalStep> predicateContributor) If no extension passed toSearchPredicateFactoryExtensionIfSupportedStep.ifSupported(SearchPredicateFactoryExtension, Function)was supported so far, apply the given consumer to the current (non-extended)SearchPredicateFactory; otherwise return the predicate created in the first succeedingifSupportedcall.If no extension passed toSearchPredicateFactoryExtensionIfSupportedStep.ifSupported(SearchPredicateFactoryExtension, Function)was supported so far, throw an exception; otherwise return the predicate created in the first succeedingifSupportedcall.

ifSupported
public <T> SearchPredicateFactoryExtensionIfSupportedMoreStep ifSupported(SearchPredicateFactoryExtension<T> extension, Function<T, ? extends PredicateFinalStep> predicateContributor) Description copied from interface:SearchPredicateFactoryExtensionIfSupportedStepIf the given extension is supported, and none of the previous extensions passed toSearchPredicateFactoryExtensionIfSupportedStep.ifSupported(SearchPredicateFactoryExtension, Function)was supported, extend the current factory with this extension, apply the given function to the extended factory, and store the resulting predicate for later retrieval.This method cannot be called after
SearchPredicateFactoryExtensionIfSupportedMoreStep.orElse(Function)orSearchPredicateFactoryExtensionIfSupportedMoreStep.orElseFail().- Specified by:
ifSupportedin interfaceSearchPredicateFactoryExtensionIfSupportedStep- Type Parameters:
T- The type of the extended factory.- Parameters:
extension- The extension to apply.predicateContributor- A function called if the extension is successfully applied; it will use the (extended) predicate factory passed in parameter to create a predicate, returning the final step in the predicate DSL. Should generally be a lambda expression.- Returns:
- The next step.
-
orElse
public PredicateFinalStep orElse(Function<SearchPredicateFactory, ? extends PredicateFinalStep> predicateContributor) Description copied from interface:SearchPredicateFactoryExtensionIfSupportedMoreStepIf no extension passed toSearchPredicateFactoryExtensionIfSupportedStep.ifSupported(SearchPredicateFactoryExtension, Function)was supported so far, apply the given consumer to the current (non-extended)SearchPredicateFactory; otherwise return the predicate created in the first succeedingifSupportedcall.- Specified by:
orElsein interfaceSearchPredicateFactoryExtensionIfSupportedMoreStep- Parameters:
predicateContributor- A function called if no extension was successfully applied; it will use the (non-extended) predicate factory passed in parameter to create a predicate, returning the final step in the predicate DSL. Should generally be a lambda expression.- Returns:
- The final step in the DSL of the resulting predicate.
