Constructor Detail

CompoundPredicate

public CompoundPredicate(com.blazebit.domain.runtime.model.DomainType type,
                         List<Predicate> predicates,
                         boolean conjunction)

Creates a new compound predicate from the given predicates as conjunction or disjunction returning a result of the given domain type.

Parameters:

type - The result domain type

predicates - The predicates

conjunction - true for conjunction, false for disjunction

CompoundPredicate

public CompoundPredicate(com.blazebit.domain.runtime.model.DomainType type,
                         List<Predicate> predicates,
                         boolean conjunction,
                         boolean negated)

Creates a new possibly negated compound predicate from the given predicates as conjunction or disjunction returning a result of the given domain type.

Parameters:

type - The result domain type

predicates - The predicates

conjunction - true for conjunction, false for disjunction

negated - true if the predicate should be negated, false otherwise

Method Detail

isConjunction

public boolean isConjunction()

Returns true if this is a conjunction, false otherwise.

Returns:

true if this is a conjunction, false otherwise

getPredicates

public List<Predicate> getPredicates()

Returns the predicates that are part of this compound predicate.

Returns:

the predicates that are part of this compound predicate

accept

public void accept(Expression.Visitor visitor)

Dynamic dispatch to one of the visit methods of the visitor, based on the runtime type.

Parameters:

visitor - The visitor to call visit on

accept

public <T> T accept(Expression.ResultVisitor<T> visitor)

Dynamic dispatch to one of the visit methods of the visitor, based on the runtime type.

Type Parameters:

T - The result type

Parameters:

visitor - The visitor to call visit on

Returns:

the value as returned by the result visitor

equals

public boolean equals(Object o)

Overrides:

equals in class AbstractPredicate

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractPredicate
