Constructor Detail

SingularAttributePath

public SingularAttributePath(CriteriaBuilderImpl criteriaBuilder,
                     Class<X> javaType,
                     PathSource pathSource,
                     SingularAttribute<?,X> attribute)

Method Detail

getAttribute

public SingularAttribute<?,X> getAttribute()

Retrieve reference to the attribute this path represents.

Specified by:

getAttribute in interface PathImplementor<X>

Returns:

The metamodel attribute.

getModel

public Bindable<X> getModel()

Return the bindable object that corresponds to the path expression.

Specified by:

getModel in interface Path<X>

Returns:

bindable object corresponding to the path

canBeDereferenced

protected boolean canBeDereferenced()

Specified by:

canBeDereferenced in class AbstractPathImpl<X>

locateAttributeInternal

protected Attribute locateAttributeInternal(String attributeName)

Description copied from class: AbstractPathImpl

Get the attribute by name from the underlying model. This allows subclasses to define exactly how the attribute is derived. Called from AbstractPathImpl.locateAttribute(java.lang.String) which also applies nullness checking for proper error reporting.

Specified by:

locateAttributeInternal in class AbstractPathImpl<X>

Parameters:

attributeName - The name of the attribute to locate

Returns:

The attribute; may be null.
