java - Validate DMN rule not overlap while adding new rule to DMN table -


i using camunda dmn in application(in angular, java, spring).

i want validate if rule not overlapping while adding new rule dmn table.

for example following dmn table,

| x | y | o/p |

| <9 | >50 | "abc" |

| <20 | >100 | "xyz" |

consider user dumb :d , , can create rules above.

now if i/p's above dmn x = 10 , y = 99 satisfy both rules.

if use unique hit policy, wont show me error @ time of add new rule rather show me while evaluation of dmn table. , dont want :(

how avoid overlapping of rules while creating of rule self using either camunda dmn js api or camunda dmn java api ?

this not possible require knowledge possible input combinations. infer overlapping value range of rules can quite hard.
