Method Detail

resolveExpression

public static EagerExpressionResolver.EagerExpressionResult resolveExpression(String expression,
                                                                              JinjavaInterpreter interpreter)

Resolve the expression while handling deferred values. Returns a EagerExpressionResult object which either holds the fully resolved object or a partially resolved string as well as a set of any words that couldn't be resolved. If a DeferredParsingException is thrown, the expression was partially resolved. If a DeferredValueException is thrown, the expression could not be resolved at all.

E.g with foo=3, bar=2: "range(0,foo)[-1] + deferred/bar" -> "2 + deferred/2"

getValueAsJinjavaStringSafe

public static String getValueAsJinjavaStringSafe(Object val)

findDeferredWords

public static Set<String> findDeferredWords(String partiallyResolved,
                                            JinjavaInterpreter interpreter)

shouldBeEvaluated

public static boolean shouldBeEvaluated(String w,
                                        JinjavaInterpreter interpreter)

                                         int maxDepth,
                                         int maxSize)
