Class QuerydslBindings

java.lang.Object

org.springframework.data.querydsl.binding.QuerydslBindings

public class QuerydslBindings
extends Object

QuerydslBindings allows definition of path specific bindings.

 
 new QuerydslBindings() {
   {
     bind(QUser.user.address.city).first((path, value) -> path.like(value.toString()));
     bind(String.class).first((path, value) -> path.like(value.toString()));
   }
 }
 
 

The bindings can either handle a single - see QuerydslBindings.PathBinder.first(SingleValueBinding) - (the first in case multiple ones are supplied) or multiple - see QuerydslBindings.PathBinder.all(MultiValueBinding) - value binding. If exactly one path is deployed, an QuerydslBindings.AliasingPathBinder is returned which - as the name suggests - allows aliasing of paths, i.e. exposing the path under a different name.

QuerydslBindings are usually manipulated using a QuerydslBinderCustomizer, either implemented directly or using a default method on a Spring Data repository.

QuerydslBindings

public QuerydslBindings()

Creates a new QuerydslBindings instance.

Method Detail

bind

public final <T extends com.querydsl.core.types.Path<S>,S> QuerydslBindings.AliasingPathBinder<T,S> bind(T path)

Returns an QuerydslBindings.AliasingPathBinder for the given Path to define bindings for them.

Parameters:

path - must not be null.

Returns:

bind

@SafeVarargs
public final <T extends com.querydsl.core.types.Path<S>,S> QuerydslBindings.PathBinder<T,S> bind(T... paths)

Returns a new QuerydslBindings.PathBinder for the given Paths to define bindings for them.

Parameters:

paths - must not be null or empty.

Returns:

bind

public final <T> QuerydslBindings.TypeBinder<T> bind(Class<T> type)

Returns a new QuerydslBindings.TypeBinder for the given type.

Parameters:

type - must not be null.

Returns:

excluding

public final void excluding(com.querydsl.core.types.Path<?>... paths)

Exclude properties from binding. Exclusion of all properties of a nested type can be done by exclusion on a higher level. E.g. address would exclude both address.city and address.street.

Parameters:

paths - must not be null or empty.

including

public final void including(com.querydsl.core.types.Path<?>... paths)

Include properties for binding. Include the property considered a binding candidate.

Parameters:

properties - must not be null or empty.

excludeUnlistedProperties

public final QuerydslBindings excludeUnlistedProperties(boolean excludeUnlistedProperties)

Returns whether to exclude all properties for which no explicit binding has been defined or it has been explicitly allowed. This defaults to false which means that for properties without an explicitly defined binding a type specific default binding will be applied.

Parameters:

excludeUnlistedProperties -

Returns:

getBindingForPath

public <S extends com.querydsl.core.types.Path<? extends T>,T> Optional<MultiValueBinding<S,T>> getBindingForPath(org.springframework.data.querydsl.binding.PathInformation path)

Returns the SingleValueBinding for the given PropertyPath. Prefers a path configured for the specific path but falls back to the builder registered for a given type.

Parameters:

path - must not be null.

Returns:

can be null.
