Джибса что есть сигнатура в данном контексте ?
Я тоже не сразу сообразил, потом вспомнил, что "гражданский" (далекий от программирования) преподаватель именно этим названием оперировал...
http://en.wikipedia.org/wiki/Type_signature#Method_signature
викиIn computer programming, especially object-oriented programming, a method is commonly identified by its unique method signature, which usually includes the method name, and the number, types and order of its parameters.[2] A method signature is the smallest type of a method.
Java
In the Java programming language, a method signature is the method name and the number and type of its parameters. Return types and thrown exceptions are not considered to be a part of the method signature.
1.
methodName(parameters) {...};
For example, the following two methods have distinct signatures:
1.
2.
doSomething(int y);
doSomething(String y);
The following three methods do have the same signatures and are considered the same, as only the return value differs. The name of the parameter is not part of the method signature and is ignored by the compiler for checking method uniqueness.
1.
2.
3.
int doSomething(int y)
String doSomething(int x)
int doSomething(int z) throws java.lang.Exception
