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>

isJpaPositionalParameter

public boolean isJpaPositionalParameter()

Description copied from interface: ParameterRegistration

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 ParameterRegistration<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.
