SearchProjectionFactoryExtensionIfSupportedMoreStep (Hibernate Search Engine 6.0.9.Final API)

Type Parameters:

R - The type of entity references in the parent SearchProjectionFactory.

E - The type of entities in the parent SearchProjectionFactory.

P - The resulting projection type.

All Superinterfaces:

SearchProjectionFactoryExtensionIfSupportedStep<P,R,E>
```
public interface SearchProjectionFactoryExtensionIfSupportedMoreStep<P,R,E>
extends SearchProjectionFactoryExtensionIfSupportedStep<P,R,E>
```
The second and later step when attempting to apply multiple extensions to a SearchProjectionFactory.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`ProjectionFinalStep<P>`	`orElse(Function<SearchProjectionFactory<R,E>,? extends ProjectionFinalStep<P>> projectionContributor)`	If no extension passed to `SearchProjectionFactoryExtensionIfSupportedStep.ifSupported(SearchProjectionFactoryExtension, Function)` was supported so far, apply the given function to the current (non-extended) `SearchProjectionFactory`; otherwise return the projection created in the first succeeding `ifSupported` call.
`ProjectionFinalStep<P>`	`orElseFail()`	If no extension passed to `SearchProjectionFactoryExtensionIfSupportedStep.ifSupported(SearchProjectionFactoryExtension, Function)` was supported so far, throw an exception; otherwise return the projection created in the first succeeding `ifSupported` call.

- Method Detail
  - orElse
```
ProjectionFinalStep<P> orElse(Function<SearchProjectionFactory<R,E>,? extends ProjectionFinalStep<P>> projectionContributor)
```
    If no extension passed to SearchProjectionFactoryExtensionIfSupportedStep.ifSupported(SearchProjectionFactoryExtension, Function) was supported so far, apply the given function to the current (non-extended) SearchProjectionFactory; otherwise return the projection created in the first succeeding ifSupported call.
    
    Parameters:
    
    projectionContributor - A function called if no extension was successfully applied; it will use the (non-extended) projection factory passed in parameter to create a projection, returning the final step in the projection DSL. Should generally be a lambda expression.
    
    Returns:
    
    The created projection.
  - orElseFail
```
ProjectionFinalStep<P> orElseFail()
```
    If no extension passed to SearchProjectionFactoryExtensionIfSupportedStep.ifSupported(SearchProjectionFactoryExtension, Function) was supported so far, throw an exception; otherwise return the projection created in the first succeeding ifSupported call.
    
    Returns:
    
    The created projection.
    
    Throws:
    
    SearchException - If none of the previously passed extensions was supported.
