Method Details

createBindings

public QueryParameterBindings createBindings(SessionFactoryImplementor sessionFactory)

Specified by:

createBindings in interface ParameterMetadataImplementor

getParameterCount

public int getParameterCount()

Description copied from interface: ParameterMetadata

The total number of registered parameters.

Specified by:

getParameterCount in interface ParameterMetadata

getInferredParameterType

public <T> BindableType<T> getInferredParameterType(QueryParameter<T> parameter)

Specified by:

getInferredParameterType in interface ParameterMetadata

containsReference

public boolean containsReference(QueryParameter<?> parameter)

Description copied from interface: ParameterMetadata

Is this parameter reference registered in this collection?

Specified by:

containsReference in interface ParameterMetadata

visitParameters

public void visitParameters(Consumer<QueryParameterImplementor<?>> consumer)

Specified by:

visitParameters in interface ParameterMetadataImplementor

getRegistrations

public Set<QueryParameterImplementor<?>> getRegistrations()

Specified by:

getRegistrations in interface ParameterMetadata

hasAnyMatching

public boolean hasAnyMatching(Predicate<QueryParameterImplementor<?>> filter)

Specified by:

hasAnyMatching in interface ParameterMetadataImplementor

resolve

public <P> QueryParameterImplementor<P> resolve(Parameter<P> param)

Description copied from interface: ParameterMetadata

A deeper resolution attempt from a JPA parameter reference to Hibernate's contract. Generally should return the same param reference. According to the spec, only Parameter references obtained from the provider are valid.

Specified by:

resolve in interface ParameterMetadata

Specified by:

resolve in interface ParameterMetadataImplementor

hasNamedParameters

public boolean hasNamedParameters()

Description copied from interface: ParameterMetadata

Does this parameter set contain any named parameters?

Specified by:

hasNamedParameters in interface ParameterMetadata

Returns:

true if there are named parameters; false otherwise.

getNamedParameterNames

public Set<String> getNamedParameterNames()

Description copied from interface: ParameterMetadata

Return the names of all named parameters of the query.

Specified by:

getNamedParameterNames in interface ParameterMetadata

Returns:

the parameter names

findQueryParameter

public QueryParameterImplementor<?> findQueryParameter(String name)

Description copied from interface: ParameterMetadata

Find the QueryParameter registered under the given name, if one.

Specified by:

findQueryParameter in interface ParameterMetadata

Specified by:

findQueryParameter in interface ParameterMetadataImplementor

Returns:

The registered match, or null is there is no match

hasPositionalParameters

public boolean hasPositionalParameters()

Description copied from interface: ParameterMetadata
