Constructor Detail

NamedParameterDescriptor

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

Constructs a NamedParameterDescriptor

Parameters:

name - The name of the parameter

expectedType - The expected type of the parameter, according to the translator

sourceLocations - The locations of the named parameters (aye aye aye)

jpaStyle - Was the parameter a JPA style "named parameter"?

Method Detail

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.

getExpectedType

public Type getExpectedType()

getSourceLocations

public int[] getSourceLocations()

isJpaStyle

public boolean isJpaStyle()

resetExpectedType

public void resetExpectedType(Type type)

Set the parameters expected type

Parameters:

type - The new expected type

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.

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
