Method Details

doRead

public <T> T doRead(ParserSession session,
 ParserPipe pipe,
 ClassMeta<T> type)
             throws IOException,
ParseException

Workhorse method.

Subclasses are expected to either implement this method or ParserSession.doRead(ParserPipe, ClassMeta).

Overrides:

doRead in class Parser

Type Parameters:

T - The class type of the object to create.

Parameters:

session - The current session.

pipe - Where to get the input from.

type - The class type of the object to create. If null or Object.class, object type is based on what's being parsed. For example, when parsing JSON text, it may return a String, Number, JsonMap, etc...

Returns:

The parsed object.

Throws:

IOException - Thrown by underlying stream.

ParseException - Malformed input encountered.
