Evaluates this predicate on the given argument.

Usage

From source file:at.gridtec.lambda4j.predicate.tri.obj.BiObjBooleanPredicate.java

/**
 * Returns a composed {@link TriDoublePredicate} that first applies the {@code before} functions to its input, and
 * then applies this predicate to the result. If evaluation of either operation throws an exception, it is relayed
 * to the caller of the composed operation. This method is just convenience, to provide the ability to execute an
 * operation which accepts {@code double} input, before this primitive predicate is executed.
 *
 * @param before1 The first function to apply before this predicate is applied
 * @param before2 The second function to apply before this predicate is applied
 * @param before3 The third predicate to apply before this predicate is applied
 * @return A composed {@code TriDoublePredicate} that first applies the {@code before} functions to its input, and
 * then applies this predicate to the result.
 * @throws NullPointerException If given argument is {@code null}
 * @implSpec The input argument of this method is a able to handle primitive values. In this case this is {@code
 * double}.//from   w  ww.  j av  a2  s .c  om
