Class ByteString.Output

java.lang.Object

java.io.OutputStream

com.google.protobuf.ByteString.Output

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

Enclosing class:

ByteString

public static final class ByteString.Output
extends OutputStream

Outputs to a ByteString instance. Call toByteString() to create the ByteString instance.

void	reset() Resets this stream, so that all currently accumulated output in the output stream is discarded.
int	size() Returns the current size of the output stream.
ByteString	toByteString() Creates a byte string with the size and contents of this output stream.
String	toString()
void	write(byte[] b, int offset, int length)
void	write(int b)

Method Detail

write

public void write(int b)

Specified by:

write in class OutputStream

write

public void write(byte[] b,
                  int offset,
                  int length)

Overrides:

write in class OutputStream

toByteString

public ByteString toByteString()

Creates a byte string with the size and contents of this output stream. This does not create a new copy of the underlying bytes. If the stream size grows dynamically, the runtime is O(log n) in respect to the number of bytes written to the ByteString.Output. If the stream size stays within the initial capacity, the runtime is O(1).

Returns:

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

writeTo

public void writeTo(OutputStream out)
             throws IOException

Writes the complete contents of this byte array output stream to the specified output stream argument.

Parameters:

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

Throws:

IOException - if an I/O error occurs.

size

public int size()

Returns the current size of the output stream.

Returns:

the current size of the output stream

reset

public void reset()

Resets this stream, 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.

toString

public String toString()

Overrides:

toString in class Object
