All Implemented Interfaces:

Closeable, Flushable

Enclosing class:

FileHandler

static class FileHandler.MeasureOutputStream
extends OutputStream

This output stream use decorator pattern to add measure feature to OutputStream which can detect the total size(in bytes) of output, the initial size can be set

Method Detail

write

public void write(int oneByte)
           throws IOException

Description copied from class: OutputStream

Writes the specified byte oneByte to this OutputStream. Only the low order byte of oneByte is written.

Specified by:

write in class OutputStream

Parameters:

oneByte - the byte to be written

Throws:

IOException - If an error occurs attempting to write to this OutputStream.

write

public void write(byte[] bytes)
           throws IOException

Description copied from class: OutputStream

Writes the entire contents of the byte array buffer to this OutputStream.

Overrides:

write in class OutputStream

Parameters:

bytes - the buffer to be written

Throws:

IOException - If an error occurs attempting to write to this OutputStream.

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

Description copied from class: OutputStream

Writes count bytes from the byte array buffer starting at offset to this OutputStream.

Overrides:

write in class OutputStream

Parameters:

b - the buffer to be written

off - offset in buffer to get bytes

len - number of bytes in buffer to write

Throws:

IOException - If an error occurs attempting to write to this OutputStream.

close

public void close()
           throws IOException

Description copied from class: OutputStream

Close this OutputStream. Concrete implementations of this class should free any resources during close. This implementation does nothing.

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException - If an error occurs attempting to close this OutputStream.

flush

public void flush()
           throws IOException

Description copied from class: OutputStream

Flush this OutputStream. Concrete implementations of this class should ensure any pending writes to the underlying stream are written out when this method is envoked. This implementation does nothing.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException - If an error occurs attempting to flush this OutputStream.

getLength

public long getLength()

setLength

public void setLength(long newLength)
