Intellij Structural Search for param type and actual type

Question

Imagine I want to search for all the methods with any number of parameters that accepts as one of them Collection but are called by passing a List. Example:

• void test1(Collection x)
• void test2(A a,Collection x)
• void test3(Collection x, B b)
• void test4(List x, B b)

and I have:

• test1(myList) # Matches
• test1(aCollection) # NO match
• test2(xxx, myList) # matches
• test3(myList, xxx) # matches
• test4(myList, xxx) # Does not match as I am looking for calls to methods that receive collection and we pass a List.

Is there a way of using Structural search for that?

Answer 1

If you want to find the calls to the methods, not the methods itself, you can use the following search template:

$call$($a$, $argument$, $b$)

With the following variable constraints:

a, b

• Minimum count: 0
• Maximum count: unlimited

argument

• Text/RegExp for java expression type: List
• Text/RegExp for formal argument type of the method: Collection
