Member Function Documentation

bool next IBuffer  buffer,
Token  token
[inline]
 

Locate the next token from the provided buffer, and map a buffer reference into token. Returns true if a token was located, false otherwise.

Note that the buffer content is not duplicated. Instead, a slice of the buffer is referenced by the token. You can use Token.clone() or Token.toString().dup() to copy content per your application needs.

Note also that there may still be one token left in a buffer that was not terminated correctly (as in eof conditions). In such cases, tokens are mapped onto remaining content and the buffer will have no more readable content.

Reimplemented from ITokenizer.

bool next IBuffer  buffer,
int(*)(char[])  scan
[inline, inherited]
 

Scan the given IBuffer for another token, and place the results in the provided token. Note that this should be completely thread-safe so one can instantiate singleton tokenizers without issue.

Each Token is expected to be stripped of the delimiter. An end-of-file condition causes trailing content to be placed into the token. Requests made beyond Eof result in empty tokens (length == zero).

Returns true if a token was isolated, false otherwise.

int notFound Token  token,
char[]  content
[inline, inherited]
 

Clean up after we fail to find a token. Trailing content is placed into the token, and the scanner is told to try and load some more content (where available).
