args - String array which may contain command line input.

Example: "-p 34 -ch abcd -d 3.2"

Throws:

ArgsException - ArgsException

parseArgumentStrings

private void parseArgumentStrings(List<String> argsList) throws ArgsException

Parses out elementId(s) from the args string. Passes them further to validate and identify the marshaler corresponding to them.

Parameters:

argsList - List of substrings of args string.

Throws:

ArgsException - ArgsException

method.

parseArgumentCharacters

private void parseArgumentCharacters(String argChars) throws ArgsException

Passes the elementId(s) extracted from args to parseArgumentCharacter method.

Parameters:

argChars - List of elementIds extracted from args string.

Throws:

ArgsException - ArgsException

parseArgumentCharacter

private void parseArgumentCharacter(char argChar) throws ArgsException

Checks if the Validates elementId character given in command line argument to check if there exists a matching schema.

Parameters:

argChar - schema given in command line input

Throws:

ArgsException - UNEXPECTED_ARGUMENT if flag don't match with schema.

method.

setArgumentCharacter

private ArgumentMarshaler setArgumentCharacter(char argChar) throws ArgsException

Checks if the elementId given in args string exists in map map. If True then marshaler corresponding to that elementId is executed.

Parameters:

argChar - element from list of elementId(s) extracted from args string.

Returns:

m Marshaler method if specified in the map for given argChar else returns null.

Throws:

ArgsException - ArgsException
