Method Detail

markSupported

public boolean markSupported()

Description copied from class: BufferedInputStream

Tests if this input stream supports the mark and reset methods. The markSupported method of BufferedInputStream returns true.

Overrides:

markSupported in class BufferedInputStream

Returns:

a boolean indicating if this stream type supports the mark and reset methods.

See Also:

InputStream.mark(int), InputStream.reset()

mark

public void mark(int readlimit)

Not supported

Overrides:

mark in class BufferedInputStream

Parameters:

readlimit - the maximum limit of bytes that can be read before the mark position becomes invalid.

reset

public void reset()
           throws IOException

Not supported

Overrides:

reset in class BufferedInputStream

Throws:

IOException - if this stream has not been marked or, if the mark has been invalidated, or the stream has been closed by invoking its BufferedInputStream.close() method, or an I/O error occurs.

read

public int read()
         throws IOException

Read a byte

Overrides:

read in class BufferedInputStream

Returns:

the next byte of data, or -1 if the end of the stream is reached.

Throws:

IOException - if this input stream has been closed by invoking its BufferedInputStream.close() method, or an I/O error occurs.

See Also:

FilterInputStream.read()

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

Checks if the bytes being read exceed the entry size and adjusts the byte array length. Updates the byte counters

Overrides:

read in class BufferedInputStream

Parameters:

b - destination buffer.

off - offset at which to start storing bytes.

len - maximum number of bytes to read.

Returns:

the number of bytes read, or -1 if the end of the stream has been reached.

Throws:

IOException - if this input stream has been closed by invoking its BufferedInputStream.close() method, or an I/O error occurs.

See Also:

FilterInputStream.read(byte[], int, int)

getNextEntry

public TarEntry getNextEntry()
                      throws IOException

Returns the next entry in the tar file

Returns:

TarEntry

Throws:

IOException

closeCurrentEntry

protected void closeCurrentEntry()
                          throws IOException

Closes the current tar entry

Throws:

IOException

skipPad

protected void skipPad()
                throws IOException

Skips the pad at the end of each tar entry file content

Throws:

IOException

skip

public long skip(long n)
          throws IOException

Skips 'n' bytes on the InputStream
Overrides default implementation of skip

Overrides:

skip in class BufferedInputStream

Throws:

IOException - if the stream does not support seek, or if this input stream has been closed by invoking its BufferedInputStream.close() method, or an I/O error occurs.

isDefaultSkip

public boolean isDefaultSkip()

setDefaultSkip

public void setDefaultSkip(boolean defaultSkip)
