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

findRootAndParameters

public void findRootAndParameters(CommonAbstractCriteriaImpl query)

Specified by:

findRootAndParameters in interface InternalSelection

Overrides:

findRootAndParameters in class FunctionExpressionImpl<java.lang.Boolean>

isPredicate

public boolean isPredicate()

Specified by:

isPredicate in interface InternalExpression

Overrides:

isPredicate in class CompoundExpressionImpl

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

not

public javax.persistence.criteria.Predicate not()

Description copied from class: CompoundExpressionImpl

Apply negation to the predicate.

Specified by:

not in interface javax.persistence.criteria.Predicate

Overrides:

not in class CompoundExpressionImpl

Returns:

the negated predicate
