template<typename T>
class Geo::GeoTokenStream

A very simple utility class that wraps some common parsing functionality around a GeoTokenList.

The token list provided in Create is just referenced, not copied, so the token list must out-live this class.

Functions

Name	Description
Create(GeoTokenList< T > &)	Creates a GeoTokenStream which reads from the given GeoTokenList.
GetCurrentTokenIdx()	Gets the index of the current token.
GetLastErrorString()	Gets a textual description of the last parsing error encountered.
HasMoreTokens()	Checks if there are more tokens to read.
Release()	Destroys this GeoTokenStream.
ResetStream()	Resets the stream to the beginning of the token list.
SetCurrentTokenIdx(s32)	Sets the stream position to the given token index.
TokenExtract(GeoString< T > &)	Parses the current token into the appropriate type, and advances the stream if successful.
TokenExtract(float &)	Parses the current token into the appropriate type, and advances the stream if successful.
TokenExtract(v128 &, bool)	Parses the current token into the appropriate type, and advances the stream if successful.
TokenExtract(u16 &)	Parses the current token into the appropriate type, and advances the stream if successful.
TokenExtract(s32 &)	Parses the current token into the appropriate type, and advances the stream if successful.
TokenExtract(bool &)	Parses the current token into the appropriate type, and advances the stream if successful.
TokenExtract(ENUM &, const T , const T )	Parses the current token into an enum, and advances the stream if successful.
TokenMatch(const T *, bool)	Checks if the current token matches the given string, and advances the stream if successful.
TokenMatchOption(const T **, s32, bool)	Checks if the current token matches the given string, and advances the stream if successful.
