extractType

public static JavaLexer.TypeDef extractType(CharSequence chars,
                                            int pos)

Extracts information from a fully qualified source name, including the (unparsed) generics string, and array depth. Specifically, the signature must be a "properly formatted" java naming-convention type definition. That is, package.names.must.be.lowercase.Class.Names.TitleCase This is intended to read in java source format only; $ is treated as a regular, legal java identifier. This method is suitable to read field, parameter and variable declarations.

Parameters:

chars - - The type signature to read.

pos - - Where to start reading

Returns:

- The end index where we finished reading. Do not send strings which may include fully qualified method or field references; instead use #extractStatement(CharSequence, int)
