This condition-attribute evaluates to true
for methods that contains instructions which invoke methods
with signatures equal to the specified signature.
The types (classes, interfaces and built-in types)
are given as a comma-separated list of type-names,
and their order is important.
The type-names follow the conventions used in Java:
Built-in types are given with their standard name, i.e.
boolean, byte,
char, double,
float, int,
long, and short,
Arrays of built-in types are given using the conventions for arrays,
e.g. "boolean[]", or
"double[][]".
Classes and interfaces are given with their fully-qualified
name, e.g. "com.abc_company.A_class".
To simplify writing of standard-classes like
"java.lang.String", "java.lang.Integer", or
"java.lang.Object", the package-name "java.lang"
may be omitted. Therefore "String", "Integer",
or "Object" are equally valid class-names. This rule applies
for classes and interfaces defined in package "java.lang" only.
To name classes or interfaces from an unnamed package, like class "MyApplet",
a dot must be prepended to the name, e.g. ".MyApplet".
Arrays of classes and interfaces are also given using the conventions for arrays,
e.g. "com.abc_company.A_class[]", "String[][]",
or ".MyApplet[]".
