Abstract

A system and method can support an object-oriented scripting tool. The system can comprise a parser that operates to parse a document that specifies a software class in a scripting language using one or more tags that are defined in a markup language environment. Furthermore, the system can include a type definition table that includes a plurality of type definitions, wherein this type definition table operates to use a tag name of a said tag as a key that is associated with a type definition. Additionally, the system can include an instance pool that operates to store one or more instances of the software class for the object-oriented scripting tool.

First claim

What is claimed is:

1. A system to support an object-oriented scripting tool, comprising:
one or more microprocessors;
a parser, running on the one or more microprocessors, that operates to parse a document that specifies a software class in a scripting language using a plurality of tags that are defined in a markup language environment, wherein the plurality of tags are configured to
define at least one method of the software class,
check whether a software object is an instance of the software class,
assign a reference value to the software class, and
write out content of a message;

a type definition table that includes a plurality of type definitions, wherein the type definition table operates to use a tag name of a said tag as a key that is associated with a type definition; and
an instance pool that operates to store one or more instances of the software class for the object-oriented scripting tool.

2. The system according to claim 1 , wherein the markup language environment uses an extensible markup language (XML) file.

3. The system according to claim 1 , wherein:
the software class allows at least one of:
class extension and inheritance,
method overriding,
instance polymorphism, and
reflection.

4. The system according to claim 1 , wherein:
the software class allows a syntax for instance method invocation in a tag, wherein the syntax includes a class reference and a method name.

5. The system according to claim 1 , wherein:
the parser operates to
determine a tag to be an unknown element in the markup language environment, and
use the tag as a key to obtain a type definition that defines the syntax for instance method invocation from the type definition table.

6. The system according to claim 1 , wherein:
a generic application build script is encapsulated into the software class, wherein another software class is extended or inherited from the software class, and wherein one or more special application build scripts operates to be executed in another software class.

7. The system according to claim 1 , wherein:
the software class is a utility class that can accept an instance of another software class as an argument.

8. The system according to claim 1 , further comprising:
the object-oriented scripting tool is used to link to a database.

9. The system according to claim 1 , further comprising:
the object-oriented scripting tool is used to deploy an application to different servers.

10. A computer-implemented method to support an object-oriented scripting tool in a markup language environment, comprising:
parsing, via a parser, a document that specifies a software class in a scripting language using a plurality of tags that are defined in a markup language environment, wherein the plurality of tags are configured to
define at least one method of the software class,
check whether a software object is an instance of the software class,
assign a reference value to the software class, and
write out content of a message;

including in a type definition table a plurality of type definitions, wherein the type definition table operates to use a tag name of a said tag as a key that is associated with a type definition; and
storing in an instance pool one or more instances of the software class for the object-oriented scripting tool.

11. The method according to claim 10 , wherein the markup language environment uses an extensible markup language (XML) file.

12. The method according to claim 10 , further comprising:
supporting at least one of:
class extension and inheritance,
method overriding,
instance polymorphism, and
reflection.

13. The method according to claim 10 , further comprising:
supporting a syntax for instance method invocation in a second tag, wherein the syntax includes a class reference and a method name.

14. The method according to claim 10 , further comprising:
determining the second tag to be an unknown element in the markup language environment, and
using the tag as a key to obtain a type definition that defines the syntax for instance method invocation from the type definition table.

15. The method according to claim 10 , further comprising:
encapsulating a generic application build script into the software class, and
executing one or more special application build scripts in another software class, wherein the another software class is extended or inherited from the software class.

16. The method according to claim 10 , further comprising:
allowing the software class to be a utility class that can accept an instance of another software class as an argument.

17. The method according to claim 16 , further comprising:
using the object-oriented scripting tool to
link to a database, and/or
deploy an application to different servers.

18. A non-transitory machine readable storage medium having instructions stored thereon that when executed by one or more microprocessors cause the one or more microprocessors to perform the steps comprising:
parsing, via a parser, a document that specifies a software class in a scripting language using a plurality of tags that are defined in a markup language environment, wherein the plurality of tags are configured to define
at least one method of the software class,
check whether a software object is an instance of the software class,
assign a reference value to the software class, and
write out content of a message;

including in a type definition table a plurality of type definitions, wherein the type definition table operates to use a tag name of a said tag as a key that is associated with a type definition; and
storing in an instance pool one or more instances of the software class for the object-oriented scripting tool.

19. The non-transitory machine readable storage medium according to claim 18 , wherein the instructions when executed further cause the one or more microprocessors to support at least one of
class extension and inheritance,
method overriding,
instance polymorphism, and
reflection.

20. The non-transitory machine readable storage medium according to claim 18 , wherein the instructions when executed further cause the one or more microprocessors to support a syntax for instance method invocation in a second tag, wherein the syntax includes a class reference and a method name.
