public class SqmJpaCriteriaParameterWrapper<T>
extends AbstractSqmExpression<T>
implements SqmParameter<T>

Acts as the per-use wrapper for a JpaCriteriaParameter (CriteriaBuilder.parameter(java.lang.Class<T>)).

JpaCriteriaParameter is the "domain query parameter" (QueryParameter while SqmJpaCriteriaParameterWrapper is the SqmParameter

 int criteriaParameterId,
 int unnamedParameterId,
 NodeBuilder criteriaBuilder)

Method Details

copy

public SqmJpaCriteriaParameterWrapper<T> copy(SqmCopyContext context)

Specified by:

copy in interface SqmExpression<T>

Specified by:

copy in interface SqmNode

Specified by:

copy in interface SqmParameter<T>

Specified by:

copy in interface SqmSelectableNode<T>

Specified by:

copy in interface SqmTypedNode<T>

getName

public String getName()

Description copied from interface: SqmParameter

If this represents a named parameter, return that parameter name; otherwise return null.

Specified by:

getName in interface Parameter<T>

Specified by:

getName in interface SqmParameter<T>

Returns:

The parameter name, or null if not a named parameter

getPosition

public Integer getPosition()

Description copied from interface: SqmParameter

If this represents a positional parameter, return that parameter position; otherwise return null.

Specified by:

getPosition in interface Parameter<T>

Specified by:

getPosition in interface SqmParameter<T>

Returns:

The parameter position

getJpaCriteriaParameter

public JpaCriteriaParameter<T> getJpaCriteriaParameter()

getCriteriaParameterId

public int getCriteriaParameterId()

The 0-based encounter of a JpaCriteriaParameter instance in a SqmQuerySource.CRITERIA query.

See Also:

• ParameterCollector

getUnnamedParameterId

public int getUnnamedParameterId()

The 0-based encounter of an unnamed JpaCriteriaParameter instance in a SqmQuerySource.CRITERIA query. If the getJpaCriteriaParameter() has a name, returns -1.

See Also:

• ParameterCollector

getParameterType

public Class<T> getParameterType()

Specified by:

getParameterType in interface Parameter<T>

allowMultiValuedBinding

public boolean allowMultiValuedBinding()

Description copied from interface: SqmParameter

Can a collection/array of values be bound to this parameter?

This is allowed in very limited contexts within the query:

1. as the value of an IN predicate if the only value is a single param
2. (in non-strict JPA mode) as the final vararg to a function

Specified by:

allowMultiValuedBinding in interface SqmParameter<T>

Returns:

true if binding collection/array of values is allowed for this parameter; false otherwise.

getAnticipatedType

public BindableType<T> getAnticipatedType()

Description copied from interface: SqmParameter

Based on the context it is declared, what is the anticipated type for bind values?

NOTE: If SqmParameter.allowMultiValuedBinding() is true, this will indicate the Type of the individual values.

Specified by:

getAnticipatedType in interface SqmParameter<T>

Returns:

The anticipated Type.

copy

public SqmParameter<T> copy()

Description copied from interface: SqmParameter

Make a copy

Specified by:

copy in interface SqmParameter<T>

accept

public <X> X accept(SemanticQueryWalker<X> walker)

Unsupported. Visitation for a criteria parameter should be handled as part of SemanticQueryWalker.visitJpaCriteriaParameter(org.hibernate.query.sqm.tree.expression.JpaCriteriaParameter<?>). This wrapper is intended just for representing unique SqmParameter references for each JpaCriteriaParameter occurrence in the SQM tree as part of the QueryParameter to SqmParameter to JdbcParameter transformation. Each occurrence requires a unique SqmParameter to make sure we ultimately get the complete set of JdbcParameter references.

Specified by:

accept in interface SqmVisitableNode

visitSubSelectableNodes

public void visitSubSelectableNodes(Consumer<SqmSelectableNode<?>> jpaSelectionConsumer)

Description copied from interface: SqmSelectableNode

Visit each of this selectable's direct sub-selectables - used to support JPA's Selection model (which is really a "selectable", just poorly named and poorly defined

Specified by:

visitSubSelectableNodes in interface SqmExpression<T>

Specified by:

visitSubSelectableNodes in interface SqmSelectableNode<T>

See Also:

• JpaSelection.getSelectionItems()
• Selection.getCompoundSelectionItems()

appendHqlString

public void appendHqlString(StringBuilder hql,
 SqmRenderContext context)

Specified by:

appendHqlString in interface SqmVisitableNode

equals

public final boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

compareTo

public int compareTo(SqmParameter<T> anotherParameter)

Specified by:

compareTo in interface Comparable<T>

Specified by:

compareTo in interface SqmParameter<T>
