CompositeProjectionBinder (Red Hat JBoss Enterprise Application Platform 8.0.0.GA public API)

java.lang.Object
- org.hibernate.search.mapper.pojo.search.definition.binding.builtin.CompositeProjectionBinder

All Implemented Interfaces:

ProjectionBinder
```
public final class CompositeProjectionBinder
extends Object
implements ProjectionBinder
```
Binds a constructor parameter to a composite projection, which will combine multiple inner projections.
The content of the composite projection is defined in the constructor parameter type by another ProjectionConstructor.
On contrary to the object projection, a composite projection is not bound to a specific object field, and thus it will always yield one and only one value.

- Method Detail
  - create
```
public static CompositeProjectionBinder create()
```
    Creates an CompositeProjectionBinder to be passed to MethodParameterMappingStep.projection(ProjectionBinder).
    
    Returns:
    
    The binder.
  - bind
```
public void bind(ProjectionBindingContext context)
```
    Description copied from interface: ProjectionBinder
    
    Binds a constructor parameter to a projection.
    The context passed in parameter provides various information about the constructor parameter being bound. Implementations are expected to take advantage of that information and to call one of the definition*(...) methods on the context to set the projection.
    
    Specified by:
    
    bind in interface ProjectionBinder
    
    Parameters:
    
    context - A context object providing information about the constructor parameter being bound, and expecting a call to one of its definition*(...) methods.
