  - parse
```
public void parse()
           throws ProcessingException
```
    Parses HTTP Request for the qualifier and argument of a command.
    Each servlet path segment, except the first (which is the command name itself), is a qualifier. Each qualifier can be either a key or a key-value pair separated by a = sign.
    Each request parameter key-value pair is an argument. A concrete command may specify mandatory arguments (e.g. type must be mandatory argument for find command, or q for query. The mandatory arguments, if any, are not captured in the argument list.
    The qualifiers and arguments are immutable after parse.
    
    Specified by:
    
    parse in interface JESTCommand
    
    Throws:
    
    ProcessingException
