Method Detail

read

int read()
         throws IOException

Read and return the next character from this Parseable as a non-negative integer, or END_OF_INPUT.

Returns:

a non-negative integer or END_OF_INPUT

Throws:

IOException - when we're unexpectedly unable to read the next character.

unread

void unread(int ch)
            throws IOException

Unread ch, such that the next call to read() will return ch. Unread can be used to unread at most one character of input.

The behavior of calling unread before the first call to read() is undefined. The behavior of calling unread(ch) with something other than ch returned by the most recent call to read() is undefined. The behavior of calling unread(ch) more than once without an intervening call to read() is undefined.

Parameters:

ch - as returned by the previous call to read().

Throws:

IOException - when we're unexpectedly unable to push back the given character.
