Constructor Detail

InImpl

public InImpl(javax.persistence.metamodel.Metamodel metamodel,
              javax.persistence.criteria.Expression leftExpression,
              java.util.List<javax.persistence.criteria.Expression<?>> compoundExpressions)

Method Detail

getExpression

public javax.persistence.criteria.Expression<T> getExpression()

Returns the expression to be tested against the list of values.

Specified by:

getExpression in interface javax.persistence.criteria.CriteriaBuilder.In<T>

Returns:

expression

value

public javax.persistence.criteria.CriteriaBuilder.In<T> value(T value)

Add to list of values to be tested against.

Specified by:

value in interface javax.persistence.criteria.CriteriaBuilder.In<T>

Parameters:

value - value

Returns:

in predicate

value

public javax.persistence.criteria.CriteriaBuilder.In<T> value(javax.persistence.criteria.Expression<? extends T> value)

Add to list of values to be tested against.

Specified by:

value in interface javax.persistence.criteria.CriteriaBuilder.In<T>

Parameters:

value - expression

Returns:

in predicate

setParentNode

public void setParentNode(Expression parentNode)

This method is used to store what will be the parent EclipseLink expression in the case the tree needs to be altered. Currently used for In.

Overrides:

setParentNode in class CompoundExpressionImpl
