Class QueryParameterNamedImpl<T>

java.lang.Object

org.hibernate.query.internal.QueryParameterImpl<T>

org.hibernate.query.internal.QueryParameterNamedImpl<T>

All Implemented Interfaces:

javax.persistence.Parameter<T>, QueryParameter<T>

public class QueryParameterNamedImpl<T>
extends QueryParameterImpl<T>
implements QueryParameter<T>

Models a named query parameter NOTE: Unfortunately we need to model named and positional parameters separately still until 6.0 NOTE : Also, notice that this still treats JPA "positional" parameters as named. This will change in 6.0 as well after we remove support for legacy positional parameters (the JPA model is better there).

QueryParameterNamedImpl

public QueryParameterNamedImpl(java.lang.String name,
                               int[] sourceLocations,
                               boolean jpaStyle,
                               Type expectedType)

Method Detail

getName

public java.lang.String getName()

Specified by:

getName in interface javax.persistence.Parameter<T>

getPosition

public java.lang.Integer getPosition()

Specified by:

getPosition in interface javax.persistence.Parameter<T>

getSourceLocations

public int[] getSourceLocations()

isJpaPositionalParameter

public boolean isJpaPositionalParameter()

Description copied from interface: QueryParameter

JPA has a different definition of positional parameters than what legacy Hibernate HQL had. In JPA, the parameter holders are labelled (named :/). At any rate the semantics are different and we often need to understand which we are dealing with (and applications might too).

Specified by:

isJpaPositionalParameter in interface QueryParameter<T>

Returns:

true if this is a JPA-style positional parameter; false would indicate we have either a named parameter (Parameter.getName() would return a non-null value) or a native Hibernate positional parameter.

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
