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. org.mycorp.A method(..)
variableNamerequiredStringName of variable to use as target for the modified method invocation.
e.g. foo
variableTyperequiredStringType attribution to use for the return type of the modified method invocation.
e.g. java.lang.String
matchOverridesBooleanWhen enabled, find methods that are overrides of the method pattern.
