Method Detail

strict

@CheckReturnValue
public static java.lang.Object strict(java.lang.Object valueOrThrowable)
                               throws CelEvaluationException

Enforces strictness. The outcome of a failed computation is represented by the value being a Throwable. Applying strict() to such a value-or-throwable will re-throw the proper exception.

Throws:

CelEvaluationException

isUnknown

public static boolean isUnknown(java.lang.Object obj)

Check if raw object is CelUnknownSet.

Parameters:

obj - Object to check.

Returns:

boolean value if object is unknown.

isAccumulatedUnknowns

public static boolean isAccumulatedUnknowns(java.lang.Object obj)

maybeAdaptToAccumulatedUnknowns

public static java.lang.Object maybeAdaptToAccumulatedUnknowns(java.lang.Object val)

If the argument is CelUnknownSet, adapts it into AccumulatedUnknowns

adaptToAccumulatedUnknowns

public static AccumulatedUnknowns adaptToAccumulatedUnknowns(CelUnknownSet unknowns)

maybeAdaptToCelUnknownSet

public static java.lang.Object maybeAdaptToCelUnknownSet(java.lang.Object val)

enforceStrictness

public static java.lang.Object enforceStrictness(java.lang.Object left,
                                                 java.lang.Object right)
                                          throws CelEvaluationException

Enforces strictness on both lhs/rhs arguments from logical operators (i.e: intentionally throws an appropriate exception when Throwable is encountered as part of evaluated result.

Throws:

CelEvaluationException

valueOrUnknown

public static java.lang.Object valueOrUnknown(@Nullable java.lang.Object valueOrThrowable,
                                              java.lang.Long id)
