public List<Object> getTokens()

This will get the tokens that were parsed from the stream.

Returns:

All of the tokens in the stream.

parseNextToken

public Object parseNextToken()
                      throws IOException

This will parse the next token in the stream.

Returns:

The next token in the stream or null if there are no more tokens in the stream.

Throws:

IOException - If an io error occurs while parsing the stream.

readOperator

protected String readOperator()
                       throws IOException

This will read an operator from the stream.

Returns:

The operator that was read from the stream.

Throws:

IOException - If there is an error reading from the stream.
