getBuffer
public java.lang.StringBuffer getBuffer() -
write
public void write(int c) throws java.io.IOException Write a single character. The character to be written is contained in the 16 low-order bits of the given integer value; the 16 high-order bits are ignored.Subclasses that intend to support efficient single-character output should override this method.
- Overrides:
write
in classjava.io.Writer
- Parameters:
c
- int specifying a character to be written.- Throws:
java.io.IOException
- If an I/O error occurs
-
write
public void write(java.lang.String str) throws java.io.IOException Write a string.- Overrides:
write
in classjava.io.Writer
- Parameters:
str
- String to be written- Throws:
java.io.IOException
- If an I/O error occurs
-
write
public void write(char[] cbuf, int off, int len) throws java.io.IOException Write a portion of an array of characters.- Specified by:
write
in classjava.io.Writer
- Parameters:
cbuf
- Array of charactersoff
- Offset from which to start writing characterslen
- Number of characters to write- Throws:
java.io.IOException
- If an I/O error occurs
-
flush
public void flush() throws java.io.IOExceptionFlush the stream. If the stream has saved any characters from the various write() methods in a buffer, write them immediately to their intended destination. Then, if that destination is another character or byte stream, flush it. Thus one flush() invocation will flush all the buffers in a chain of Writers and OutputStreams. If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive.- Specified by:
flush
in interfacejava.io.Flushable
- Specified by:
flush
in classjava.io.Writer
- Throws:
java.io.IOException
- If an I/O error occurs
-
close
public void close() throws java.io.IOExceptionClose the stream, flushing it first. Once a stream has been closed, further write() or flush() invocations will cause an IOException to be thrown. Closing a previously-closed stream, however, has no effect.- Specified by:
close
in interfacejava.lang.AutoCloseable
- Specified by:
