All known Subclasses: org.apache.pluto.util.assemble.ear.ByteArrayAssemblySink, org.apache.pluto.util.assemble.ear.FileAssemblySink,
| AssemblySink | | abstract class AssemblySink extends FilterOutputStream (Code) | | Used as a temporary container for assembled bytes, and for tracking
metadata specific to JarEntry objects, especially the
size of the JarEntry and its checksum.
|
| Field Summary | |
| final protected Checksum | CRC
The CRC-32 calculator. | | protected static int | DEFAULT_BUFLEN
The default buffer length used when reading and
writing to the sink. | | protected long | count
The number of bytes written to the sink. |
| Constructor Summary | |
| | AssemblySink()
Constructs a sink with null as an
underlying output stream. | | | AssemblySink(OutputStream out)
Constructs a sink with out as the
underlying output stream. |
| Method Summary | |
| public void | close()
Closes the underlying output stream, resets the
checksum calculator, and clears the byte count. | | long | getByteCount()
Obtain the number of bytes written to the sink. | | long | getCrc()
Obtain the checksum of the bytes written to
the sink to this point. | | public synchronized void | write(byte[] b)
| | public synchronized void | write(byte[] b, int off, int len)
| | public synchronized void | write(int b)
| | void | writeTo(OutputStream out)
Write out the bytes in the sink to the supplied
output stream, using the default buffer length. | | abstract void | writeTo(OutputStream out, int buflen)
Write out the bytes in the sink to the supplied
output stream, using the supplied buffer length. |
| DEFAULT_BUFLEN | | protected static int DEFAULT_BUFLEN(Code) | | The default buffer length used when reading and
writing to the sink. By default the value is
4096 bytes.
|
| count | | protected long count(Code) | | The number of bytes written to the sink.
|
| AssemblySink | | AssemblySink()(Code) | | Constructs a sink with null as an
underlying output stream.
|
| AssemblySink | | AssemblySink(OutputStream out)(Code) | | Constructs a sink with out as the
underlying output stream. Method calls
on the sink are delegated to the underlying
output stream.
Parameters:
out - the underlying output stream. |
| close | | public void close() throws IOException(Code) | | Closes the underlying output stream, resets the
checksum calculator, and clears the byte count.
|
| getByteCount | | long getByteCount()(Code) | | Obtain the number of bytes written to the sink.
the number of bytes written to the sink |
| getCrc | | long getCrc()(Code) | | Obtain the checksum of the bytes written to
the sink to this point.
the CRC-32 checksum of the bytes in the sink |
| write | | public synchronized void write(byte[] b, int off, int len) throws IOException(Code) | | |
| writeTo | | void writeTo(OutputStream out) throws IOException(Code) | | Write out the bytes in the sink to the supplied
output stream, using the default buffer length.
Parameters:
out - the OutputStream the sink should be copied to.
throws:
IOException - |
| writeTo | | abstract void writeTo(OutputStream out, int buflen) throws IOException(Code) | | Write out the bytes in the sink to the supplied
output stream, using the supplied buffer length.
Parameters:
out - the OutputStream the sink should be copied to.
Parameters:
buflen - the buffer length used when copying bytes
throws:
IOException - |
