A closed stream cannot perform output operations and cannot be reopened.

public void close()

Overrides java.io.OutputStream.close.

Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.

flush back to summary

flush	back to summary
public void flush() Overrides java.io.OutputStream.flush. Implements java.io.Flushable.flush. Doc from java.io.OutputStream.flush. Flushes this output stream and forces any buffered output bytes to be written out. The general contract of `flush` is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination. 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.

public void flush()

Overrides java.io.OutputStream.flush.

Implements java.io.Flushable.flush.

Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

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.

write back to summary

write	back to summary
public void write(byte[] b) Overrides java.io.OutputStream.write. Doc from java.io.OutputStream.write. Writes `b.length` bytes from the specified byte array to this output stream. The general contract for `write(b)` is that it should have exactly the same effect as the call `write(b, 0, b.length)`. Parameters b:byte[] the data.

public void write(byte[] b)

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes b.length bytes from the specified byte array to this output stream. The general contract for write(b) is that it should have exactly the same effect as the call write(b, 0, b.length).

Parameters

b:byte[]: the data.

write back to summary

public void write(byte[] b, int i, int l)

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

If b is null, a NullPointerException is thrown.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

Parameters

b:byte[]: the data.
i:int: the start offset in the data.
l:int: the number of bytes to write.

write back to summary

public void write(int b)

Implements abstract java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Parameters

b:int: the byte.

Method Detail

back to summary

public void close()

Implements abstract java.io.Writer.close.

Implements java.io.Closeable.close.

Doc from java.io.Writer.close.

Closes the stream, flushing it first. Once the stream has been closed, further write() or flush() invocations will cause an IOException to be thrown. Closing a previously closed stream has no effect.

flush

back to summary

public void flush()

Implements abstract java.io.Writer.flush.

Implements java.io.Flushable.flush.

Doc from java.io.Writer.flush.

Flushes 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.

write

Parameters

public void write(char[] b, int o, int l)

Implements abstract java.io.Writer.write.

o:int: Offset from which to start writing characters
l:int: Number of characters to write

write

back to summary

public void write(int b)

Overrides java.io.Writer.write.

Doc from java.io.Writer.write.

Writes 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.

Parameters

b:int: int specifying a character to be written

write

public void write(String s)

Writes a string.
