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. |
