Java io stringreader source code

Java io stringreader source code

Skips the specified number of characters in the stream. Returns the number of characters that were skipped. The ns parameter may be negative, even though the skip method of the Reader superclass throws an exception in this case. Negative values of ns cause the stream to skip backwards. Negative return values indicate a skip backwards. It is not possible to skip backwards past the beginning of the string. If the entire string has been read or skipped, then this method has no effect and always returns 0.

public boolean markSupported()

mark

Marks the present position in the stream. Subsequent calls to reset() will reposition the stream to this point.

reset

Resets the stream to the most recent mark, or to the beginning of the string if it has never been marked.

close

Closes the stream and releases any system resources associated with it. Once the stream has been closed, further read(), ready(), mark(), or reset() invocations will throw an IOException. Closing a previously closed stream has no effect.

Resets the stream to the most recent mark, or to the beginning of the string if it has never been marked.

StringReader

Method Details

read

read

Reads characters into a portion of an array. If len is zero, then no characters are read and 0 is returned; otherwise, there is an attempt to read at least one character. If no character is available because the stream is at its end, the value -1 is returned; otherwise, at least one character is read and stored into cbuf .

skip

Skips characters. If the stream is already at its end before this method is invoked, then no characters are skipped and zero is returned. The n parameter may be negative, even though the skip method of the Reader superclass throws an exception in this case. Negative values of n cause the stream to skip backwards. Negative return values indicate a skip backwards. It is not possible to skip backwards past the beginning of the string. If the entire string has been read or skipped, then this method has no effect and always returns 0 .

Closing a previously closed stream has no effect. This method will block while there is another thread blocking on the reader.
