Instance Method Summary collapse
-
#error? ⇒ Boolean
Tells you whether the parser is in an error state.
-
#execute(req_hash, data) ⇒ Integer
Takes a Hash and a String of data, parses the String of data filling in the Hash returning an Integer to indicate how much of the data has been read.
-
#finish ⇒ Object
Finishes a parser early which could put in a “good” or bad state.
-
#finished? ⇒ Boolean
Tells you whether the parser is finished or not and in a good state.
-
#new ⇒ Object
constructor
Creates a new parser.
-
#nread ⇒ Integer
Returns the amount of data processed so far during this processing cycle.
-
#reset ⇒ nil
Resets the parser to it’s initial state so that you can reuse it rather than making new ones.

#execute(req_hash, data) ⇒ Integer
Takes a Hash and a String of data, parses the String of data filling in the Hash returning an Integer to indicate how much of the data has been read. No matter what the return value, you should call HttpParser#finished? and HttpParser#error? to figure out if it’s done parsing or there was an error.
This function now throws an exception when there is a parsing error. This makes the logic for working with the parser much easier. You can still test for an error, but now you need to wrap the parser with an exception handling block.

#finish ⇒ Object
Finishes a parser early which could put in a “good” or bad state. You should call reset after finish it or bad things will happen.

#nread ⇒ Integer
Returns the amount of data processed so far during this processing cycle. It is set to 0 on initialize or reset calls and is incremented each time execute is called.
