Method Detail
-
read
public int read() throws java.io.IOExceptionDeprecated.Read a single character. This method will block until a character is available, an I/O error occurs, or the end of the stream is reached.Subclasses that intend to support efficient single-character input should override this method.
- Overrides:
readin classjava.io.Reader- Returns:
- The character read, as an integer in the range 0 to 16383
(
0x00-0xffff), or -1 if the end of the stream has been reached - Throws:
java.io.IOException- If an I/O error occurs
-
read
public int read(char[] ch, int offset, int length) throws java.io.IOExceptionDeprecated.Read characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached.- Specified by:
readin classjava.io.Reader- Parameters:
ch- Destination bufferoffset- Offset at which to start storing characterslength- Maximum number of characters to read- Returns:
- The number of characters read, or -1 if the end of the stream has been reached
- Throws:
java.io.IOException- If an I/O error occurs
-
skip
public long skip(long n) throws java.io.IOExceptionDeprecated.Skip characters. This method will block until some characters are available, an I/O error occurs, or the end of the stream is reached.- Overrides:
skipin classjava.io.Reader- Parameters:
n- The number of characters to skip- Returns:
- The number of characters actually skipped
- Throws:
java.io.IOException- If an I/O error occurs
-
ready
public boolean ready() throws java.io.IOExceptionDeprecated.Tell whether this stream is ready to be read.- Overrides:
readyin classjava.io.Reader- Returns:
- True if the next read() is guaranteed not to block for input, false otherwise. Note that returning false does not guarantee that the next read will block.
- Throws:
java.io.IOException- If an I/O error occurs
-
markSupported
public boolean markSupported()
Deprecated.Tell whether this stream supports the mark() operation.- Overrides:
markSupportedin classjava.io.Reader
-
mark
public void mark(int readAheadLimit) throws java.io.IOExceptionDeprecated.Mark the present position in the stream. Subsequent calls to reset() will attempt to reposition the stream to this point. Not all character-input streams support the mark() operation.- Overrides:
markin classjava.io.Reader- Parameters:
readAheadLimit- Limit on the number of characters that may be read while still preserving the mark. After reading this many characters, attempting to reset the stream may fail.- Throws:
java.io.IOException- If the stream does not support mark(), or if some other I/O error occurs
-
reset
public void reset() throws java.io.IOExceptionDeprecated.Reset the stream. If the stream has been marked, then attempt to reposition it at the mark. If the stream has not been marked, then attempt to reset it in some way appropriate to the particular stream, for example by repositioning it to its starting point. Not all character-input streams support the reset() operation, and some support reset() without supporting mark().- Overrides:
resetin classjava.io.Reader- Throws:
java.io.IOException- If the stream has not been marked, or if the mark has been invalidated, or if the stream does not support reset(), or if some other I/O error occurs
-
close
public void close() throws java.io.IOExceptionDeprecated.Close the stream. Once a stream has been closed, further read(), ready(), mark(), or reset() invocations will throw an IOException. Closing a previously-closed stream, however, has no effect.- Specified by:
closein interfacejava.lang.AutoCloseable- Specified by:
closein interfacejava.io.Closeable- Specified by:
closein classjava.io.Reader- Throws:
java.io.IOException- If an I/O error occurs
