Add direct accessors for children in FASTTypescriptMethod_definition

[knowbased]

Description:

Right now, getting information like the method name, parameters, statements, or modifier from a FASTTypescriptMethod_definition means searching through the children array and picking out the right element by its class.

Proposal:

We could add direct accessors for the following children:

• identifier (the TypescriptProperty_identifier, for the method name)
• statements (the TypescriptStatement_block, for the method body)
• parameters (the method’s TypescriptProperty_identifier parameters)
• modifier (the TypescriptAccessibility_modifier)

Example:

Current way to get the method name:

(method children detect: [:c | c className = 'TypescriptProperty_identifier']) sourceCode.

With the proposed change:

method identifier sourceCode.

Thank you for your contribution, I added 3 new properties:

• #name for identifier
• #body for statements
• #return_type for type (it is optional)

Still have #parameters but cannot be done now until we figure out the issue of properties returning collection of items.

Update: #parameters is added
