Method Detail

getExpression

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

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

Specified by:

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

Returns:

expression

findRootAndParameters

public void findRootAndParameters(CommonAbstractCriteriaImpl query)

Specified by:

findRootAndParameters in interface InternalSelection

Overrides:

findRootAndParameters in class FunctionExpressionImpl<Boolean>

isPredicate

public boolean isPredicate()

Specified by:

isPredicate in interface InternalExpression

Overrides:

isPredicate in class CompoundExpressionImpl

value

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

Add to list of values to be tested against.

Specified by:

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

Parameters:

value - value

Returns:

in predicate

value

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

Add to list of values to be tested against.

Specified by:

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

Parameters:

value - expression

Returns:

in predicate

setParentNode
