Constructor Detail

OrdinalParameterDescriptor

public OrdinalParameterDescriptor(int ordinalPosition,
                                  Type expectedType,
                                  int sourceLocation)

Constructs an ordinal parameter descriptor.

Parameters:

ordinalPosition - The ordinal position

expectedType - The expected type of the parameter

sourceLocation - The location of the parameter

Method Detail

getOrdinalPosition

public int getOrdinalPosition()

getExpectedType

public Type getExpectedType()

getSourceLocation

public int getSourceLocation()

getType

public Type getType()

Description copied from interface: QueryParameter

Get the Hibernate Type associated with this parameter.

Specified by:

getType in interface QueryParameter

Returns:

The Hibernate Type.

getName

public java.lang.String getName()

Specified by:

getName in interface javax.persistence.Parameter

getPosition

public java.lang.Integer getPosition()

Specified by:

getPosition in interface javax.persistence.Parameter

getParameterType

public java.lang.Class getParameterType()

Specified by:

getParameterType in interface javax.persistence.Parameter

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

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.
