		const DString &	fileName,
		int	startLine,
		const Definition *	ctx,
		const MemberDef *	md,
		const DString &	input,
		const DocOptions &	options )

Main entry point for the comment block parser.

Parameters

parserIntf	The parser object created via createDocParser()
fileName	File in which the documentation block is found (or the name of the example file in case isExample is true).
startLine	Line at which the documentation block is found.
ctx	Class or namespace to which this block belongs.
md	Member definition to which the documentation belongs. Can be 0.
input	String representation of the documentation block.
options	Optional parameters.

Returns

An object representing the abstract syntax tree. Ownership of the pointer is handed over to the caller.
