Abstract

Methods and apparatuses for use in applying an update to a communication protocol in a software application that is executed by a computing device are described herein. The computing device receives a protocol definition corresponding to a communication protocol and indicating positions of data elements within data objects corresponding to the communication protocol. When the computing device determines that the received protocol definition differs from a previous protocol definition corresponding to the communication protocol, the computing device creates a machine-executable object parser based on the received protocol definition. The machine-executable object parser is accessible to a software application executed by the computing device. The software application receives a data object corresponding to the communication protocol, and the computing device executes the machine-executable object parser to parse at least a portion of the data elements in the data object received by the software application.

1. A method for applying an update to a communication protocol in a software application executed by a computing device, the method comprising:

storing a first machine-executable object parser configured to parse received data objects based on a communication protocol, wherein the first machine-executable object parser is associated with a first timestamp, and wherein the first machine-executable object parser is based on a first protocol definition, wherein the first protocol definition indicates positions of data elements within data objects corresponding to the communication protocol;

executing, by the computer device, the software application including the first machine-executable object parser, wherein the first machine-executable object parser is loaded in active memory of the computing device and is in communication with the software application;

receiving, by the computing device, a second protocol definition corresponding to the communication protocol, wherein the second protocol definition indicates positions of data elements within data objects corresponding to the communication protocol, and wherein the second protocol definition includes a second timestamp;

determining, by the computing device, that the second protocol definition differs from the first protocol definition;

determining that the second timestamp is newer than the first timestamp;

upon determining that the second timestamp is newer than the first timestamp, automatically creating, by the computing device and without pausing execution of the software application, a second machine-executable object parser based on the second protocol definition;

replacing the first machine-executable object parser in active memory with the second machine-executable object parser;

receiving, by the software application, a data object corresponding to the communication protocol; and

executing, by the computing device, the second machine-executable object parser to parse at least a portion of the data elements in the data object received by the software application and communicating the parsed data elements to the software application.

2. The method in accordance with claim 1, wherein the second machine-executable object parser is created by the computing device without prompting a user of the computing device to approve the creation of the second machine-executable object parser.

3. The method in accordance with claim 1, wherein creating the second machine-executable object parser comprises generating source code based on the second protocol definition.

4. The method in accordance with claim 3, wherein creating the second machine-executable object parser further comprises compiling the generated source code.

5. The method in accordance with claim 1, wherein creating the second machine-executable object parser comprises:

determining that the second protocol definition corresponds to a protocol definition format; and

parsing the second protocol definition based on the protocol definition format.

6. The method in accordance with claim 1, wherein the second machine-executable object parser is not created when the second protocol definition and the first protocol definition do not differ.

7. The method in accordance with claim 1, the method further comprising:

storing, by the computing device, the created second machine-executable object parser; and

executing, by the computing device, the second machine-executable object parser to parse data elements in data objects received by the software application until a third protocol definition corresponding to the communication protocol and differing from the second protocol definition is received by the computing device.

17. The method in accordance with claim 1, wherein the data object is encoded in binary form, and wherein the method further comprises determining the type of data contained in the binary data based on values in particular byte positions.

18. The method in accordance with claim 1, wherein automatically creating the second machine-executable object parser based on the second protocol definition comprises creating human-readable source code based on the second protocol definition.

19. The method in accordance with claim 1, wherein automatically creating the second machine-executable object parser based on the received protocol definition comprises converting the definition directly to an intermediate language.

20. The method in accordance with claim 19, further comprising selecting intermediate language instructions based on an efficiency of the language instructions.
