Method Detail

getAvailable

public int getAvailable()

Description copied from class: StreamImpl

Returns the number of bytes available without blocking. Depending on the stream, this may return less than the actual bytes, but will always return a number > 0 if there is any data available.

Overrides:

getAvailable in class StreamImpl

canRead

public boolean canRead()

Description copied from class: StreamImpl

Returns true if this is a read stream.

Overrides:

canRead in class StreamImpl

read

public int read(byte[] buf,
                int bufOffset,
                int length)
         throws java.io.IOException

Description copied from class: StreamImpl

Reads the next chunk from the stream.

Overrides:

read in class StreamImpl

Parameters:

buf - byte array receiving the data.

bufOffset - starting offset into the array.

length - number of bytes to read.

Returns:

the number of bytes read or -1 on end of file.

Throws:

java.io.IOException

getPosition

public int getPosition()

seekStart

public void seekStart(long pos)

Description copied from class: StreamImpl

Seeks based on the start.

Overrides:

seekStart in class StreamImpl

canWrite

public boolean canWrite()

Description copied from class: StreamImpl

Returns true if this is a writable stream.

Overrides:

canWrite in class StreamImpl

write

public void write(byte[] buf,
                  int offset,
                  int length,
                  boolean isEnd)
           throws java.io.IOException

Writes a buffer to the underlying stream.

Overrides:

write in class StreamImpl

Parameters:

buffer - the byte array to write.

offset - the offset into the byte array.

length - the number of bytes to write.

isEnd - true when the write is flushing a close.

Throws:

java.io.IOException

flushToDisk

public void flushToDisk()

Description copied from class: StreamImpl

Flushes the write output, forcing to disk.

Overrides:

flushToDisk in class StreamImpl

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
