closeEntry	back to summary
public void closeEntry() throws IOException Close an entry. This method MUST be called for all file entries that contain data. The reason is that we must buffer data written to the stream in order to satisfy the buffer's record based writes. Thus, there may be data fragments still being assembled that must be written to the output stream before this entry is closed and the next entry written. Exceptions IOException: on error

write

back to summary

public void write(int b) throws IOException

Overrides java.io.FilterOutputStream.write.

write

back to summary

public void write(byte[] wBuf) throws IOException

Overrides java.io.FilterOutputStream.write.

@Override

Exceptions

IOException:: on error

write

back to summary

public void write(byte[] wBuf, int wOffset, int numToWrite) throws IOException

Overrides java.io.FilterOutputStream.write.

Writes bytes to the current tar archive entry. This method is aware of the current entry and will throw an exception if you attempt to write bytes past the length specified for the current entry. The method is also (painfully) aware of the record buffering required by TarBuffer, and manages buffers that are not a multiple of recordsize in length, including assembling records from small buffers.

Parameters

wBuf:byte[]: The buffer to write to the archive.
wOffset:int: The offset in the buffer from which to get bytes.
numToWrite:int: The number of bytes to write.

Annotations
