org.tensorics.core.expressions.BinaryPredicateExpression<T>

Type Parameters:

T - the type of the results of the operands

All Implemented Interfaces:

java.io.Serializable, Expression<java.lang.Boolean>, Node

Direct Known Subclasses:

IsEqualToExpression, IsNotEqualExpression

public class BinaryPredicateExpression<T>
extends AbstractDeferredExpression<java.lang.Boolean>
implements java.io.Serializable

An unresolved expression which can be resolved by applying a binary predicate on the results of the two operands (left, right). Any instance contains the binary predicate itself as well as expressions for both operands.
