| Name | Type | Description |
|---|---|---|
methodPatternrequired | String | A method pattern is used to find matching method invocations. For example, to find all method invocations in the Guava library, use the pattern: com.google.common..*#*(..).The pattern format is <PACKAGE>#<METHOD_NAME>(<ARGS>). ..* includes all subpackages of com.google.common. *(..) matches any method name with any number of arguments. For more specific queries, like Guava's ImmutableMap, use com.google.common.collect.ImmutableMap#*(..) to narrow down the results.e.g. com.yourorg.A foo(int, int) |
argumentIndexrequired | int | A zero-based index that indicates which argument will be added as null to the method invocation. e.g. 0 |
parameterTyperequired | String | The type of the parameter that we add the argument for. e.g. java.lang.String |
parameterName | String | The name of the parameter that we add the argument for. e.g. name |
explicitCast | Boolean | Explicitly cast the argument to the parameter type. Useful if the method is overridden with another type. e.g. true |
