Options

NameTypeDescription
methodPatternrequiredStringA 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. java.util.List add(..)
matchOverridesBooleanWhen enabled, match methods that are overrides of the method pattern. Default is true.
exceptionTypePatternrequiredStringA type pattern that is used to find matching exception to remove. Use * to match all.
e.g. java.io.IOException
