Method Detail

getType

Type getType()

Get the Hibernate Type associated with this parameter.

Returns:

The Hibernate Type.

isJpaPositionalParameter

boolean isJpaPositionalParameter()

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).

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.
