Method Detail

predicateTrueForEachLeafExpression

public static boolean predicateTrueForEachLeafExpression(EntityCondition input,
                                                         com.google.common.base.Predicate<EntityExpr> predicate)

Traverses input EntityCondition and checks of predicate is true for each leaf EntityExpr (that does not contain sub-conditions)

Parameters:

input - EntityCondition to be checked

predicate - to be applied to each leaf EntityExpr

Returns:

false if at least for one EntityExpr predicate was not true

transformCondition

public static EntityCondition transformCondition(EntityCondition input,
                                                 com.google.common.base.Function<EntityExpr,EntityCondition> function)

Traverses input EntityCondition and each leaf EntityExpr (that does not contain sub-conditions) is transformed with function

Parameters:

input - EntityCondition to be transformed

function - to be applied to each leaf EntityExpr

Returns:

rewritten EntityCondition of the same structure except for leaf expressions transformed by function
