我有一个条件语句声称'表达式太复杂,无法在合理的时间内解决。如果在我的条件中有超过5个包含语句,它会失败的那个错误。这似乎不应该发生在编译,看到作为语句不是那么复杂。这是其他人遇到的错误吗?除了分裂我的条件,有没有解决方案?
I have a conditional statement that claims the 'Expression was too complex to be solved in reasonable time. If there are any more than around 5 contains statements in my conditional, it fails with that error. This does not seem like something that should be happening on compile, seeing as the statement isn't all that complex. Is this a bug that anyone else has run into? Is there a solution other than splitting up my conditions?
else if( contains(JSONDict.keys.array, "id") && contains(JSONDict.keys.array, "part_number") && contains(JSONDict.keys.array, "sales_part_number") && contains(JSONDict.keys.array, "include_in_search") && contains(JSONDict.keys.array, "description") && contains(JSONDict.keys.array, "brand") && contains(JSONDict.keys.array, "product_group") && contains(JSONDict.keys.array, "product_design") && contains(JSONDict.keys.array, "material") && contains(JSONDict.keys.array, "line") && contains(JSONDict.keys.array, "unit_of_mass") && contains(JSONDict.keys.array, "coating") && contains(JSONDict.keys.array, "pcs_converstion") && contains(JSONDict.keys.array, "appRim") && contains(JSONDict.keys.array, "appSegment") && contains(JSONDict.keys.array, "series") && contains(JSONDict.keys.array, "product_application") ){ }推荐答案
是的,这是一个已知问题 - 另请参见此答案。
Yes that's a known issue - see also this answer.
解决方案是使用多行语句将逻辑表达式存储到变量中:
The solution is to store the logical expression into a variable, using a multiline statement:
else { var logicalExpression = contains(JSONDict.keys.array, "id") && contains(JSONDict.keys.array, "part_number") && contains(JSONDict.keys.array, "sales_part_number") && contains(JSONDict.keys.array, "include_in_search") logicalExpression = logicalExpression && contains(JSONDict.keys.array, "description") && contains(JSONDict.keys.array, "brand") && contains(JSONDict.keys.array, "product_group") && contains(JSONDict.keys.array, "product_design") // ... etc. if logicalExpression { } }对于这么强大的语言来说有点奇怪...但是这是一个(希望暂时的)折衷。
A little weird for such a powerful language... but it's a (hopefully temporary) trade off.
