public class GridByteArrayOutputStream
extends OutputStream

This class defines output stream backed by byte array. It is identical to ByteArrayOutputStream with no synchronization.

Constructor Detail

GridByteArrayOutputStream

public GridByteArrayOutputStream()

Creates a new byte array output stream. The buffer capacity is initially 32 bytes, though its size increases if necessary.

GridByteArrayOutputStream

public GridByteArrayOutputStream(int size)

Parameters:

size - Byte array size.

GridByteArrayOutputStream

public GridByteArrayOutputStream(int size,
                                 int off)

Parameters:

size - Byte array size.

off - Offset from which to write.

Method Detail

write

public void write(int b)

Writes the specified byte to this byte array output stream.

Specified by:

write in class OutputStream

Parameters:

b - the byte to be written.

write

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

Writes len bytes from the specified byte array starting at offset off to this byte array output stream.

Overrides:

write in class OutputStream

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

writeTo

public void writeTo(OutputStream out)
             throws IOException

Writes the complete contents of this byte array output stream to the specified output stream argument, as if by calling the output stream's write method using out.write(buf, 0, count).

Parameters:

out - the output stream to which to write the data.

Throws:

IOException - if an I/O error occurs.

reset

public void reset()

Resets the count field of this byte array output stream to zero, so that all currently accumulated output in the output stream is discarded. The output stream can be used again, reusing the already allocated buffer space.

See Also:

ByteArrayInputStream.count

internalArray

public byte[] internalArray()

Returns internal array without copy (use with care).

Returns:

Internal array without copy.

toByteArray

public byte[] toByteArray()

Creates a newly allocated byte array. Its size is the current size of this output stream and the valid contents of the buffer have been copied into it.

Returns:

the current contents of this output stream, as a byte array.

See Also:

ByteArrayOutputStream.size()

size

public int size()

Returns the current size of the buffer.

Returns:

the value of the count field, which is the number of valid bytes in this output stream.

See Also:

ByteArrayOutputStream.count

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

toString

public String toString()

Overrides:

toString in class Object
