Method Detail

isNegated

public boolean isNegated()

Description copied from interface: Predicate

Whether the predicate has been created from another predicate by applying the Predicate.not() method or the CriteriaBuilder.not() method.

Specified by:

isNegated in interface Predicate

Returns:

boolean indicating if the predicate is a negated predicate

not

public Predicate not()

Description copied from interface: Predicate

Create a negation of the predicate.

Specified by:

not in interface Predicate

Returns:

negated predicate

isCompoundSelection

public final boolean isCompoundSelection()

Description copied from interface: Selection

Whether the selection item is a compound selection.

Specified by:

isCompoundSelection in interface Selection<Boolean>

Overrides:

isCompoundSelection in class SelectionImpl<Boolean>

Returns:

boolean indicating whether the selection is a compound selection

getCompoundSelectionItems

public final List<Selection<?>> getCompoundSelectionItems()

Description copied from interface: Selection

Return the selection items composing a compound selection. Modifications to the list do not affect the query.

Specified by:

getCompoundSelectionItems in interface Selection<Boolean>

Overrides:

getCompoundSelectionItems in class SelectionImpl<Boolean>

Returns:

list of selection items
