Abstract

Techniques for accessing a migrated method include: identifying a request to invoke a method defined by a type, the request including one or more arguments associated with respective argument types; identifying, in the type, an older version of the method associated with (a) a method name and (b) a first set of one or more parameter types, and a current version of the method associated with (a) the method name and (b) a second set of one or more parameter types; determining that the argument type(s) match(es) the first set of one or more parameter types; responsive to determining that the argument type(s) match(es) the first set of one or more parameter types: applying one or more conversion functions to convert the argument(s) to the second set of one or more parameter types; executing the current version of the method using the converted argument(s).

Claims20

Dependent claims

One or more non-transitory machine-readable media storing instructions that, when executed by one or more processors, cause performance of operations comprising:

identifying a first request to invoke a method defined by a particular type, the first request comprising a first set of one or more arguments associated with a first set of one or more argument types;
identifying, in the particular type:
an older version of the method that is associated with (a) a particular method name and (b) a first set of one or more parameter types;
a current version of the method that is associated with (a) the particular method name and (b) a second set of one or more parameter types that is different from the first set of one or more parameter types;
determining that the first set of one or more argument types matches the first set of one or more parameter types associated with the older version of the method;
responsive to determining that the first set of one or more argument types matches the first set of one or more parameter types associated with the older version of the method:
applying a first set of one or more conversion functions to convert the first set of one or more arguments to the second set of one or more parameter types associated with the current version of the method;
executing the current version of the method using the converted first set of one or more arguments.

5 more elements

A system comprising:

at least one device comprising one or more hardware processors,
the system being configured to cause the one or more hardware processors to perform operations comprising:
identifying a first request to invoke a method defined by a particular type, the first request comprising a first set of one or more arguments associated with a first set of one or more argument types;
identifying, in the particular type:
an older version of the method that is associated with (a) a particular method name and (b) a first set of one or more parameter types;
a current version of the method that is associated with (a) the particular method name and (b) a second set of one or more parameter types that is different from the first set of one or more parameter types;
determining that the first set of one or more argument types matches the first set of one or more parameter types associated with the older version of the method;
responsive to determining that the first set of one or more argument types matches the first set of one or more parameter types associated with the older version of the method:
applying a first set of one or more conversion functions to convert the first set of one or more arguments to the second set of one or more parameter types associated with the current version of the method;
executing the current version of the method using the converted first set of one or more arguments.

7 more elements

A method comprising:

identifying a first request to invoke a method defined by a particular type, the first request comprising a first set of one or more arguments associated with a first set of one or more argument types;
identifying, in the particular type:
an older version of the method that is associated with (a) a particular method name and (b) a first set of one or more parameter types;
a current version of the method that is associated with (a) the particular method name and (b) a second set of one or more parameter types that is different from the first set of one or more parameter types;
determining that the first set of one or more argument types matches the first set of one or more parameter types associated with the older version of the method;
responsive to determining that the first set of one or more argument types matches the first set of one or more parameter types associated with the older version of the method:
applying a first set of one or more conversion functions to convert the first set of one or more arguments to the second set of one or more parameter types associated with the current version of the method;
executing the current version of the method using the converted first set of one or more arguments;
wherein the method is performed by at least device comprising one or more hardware processors.
