public class Invoke extends PatternElement
Invoke objects match by class name, method name, method signature, and mode.
Names and signatures may be matched in several ways:
The mode specifies what kind of invocations in the Invoke element matches. It is specified as the bitwise combination of the following values:
INSTANCE
, which matches ordinary instance method invocations
STATIC
, which matches static method invocations
CONSTRUCTOR
, which matches object constructor invocations
ORDINARY_METHOD
is equivalent to
INSTANCE|STATIC
. The special mode ANY
is equivalent
to INSTANCE|STATIC|CONSTRUCTOR
