length

public long length()
            throws IOException

Description copied from interface: ReadOnlyFile

Returns the length of the file in bytes.

Specified by:

length in interface ReadOnlyFile

Overrides:

length in class DecoratingReadOnlyFile

Throws:

IOException

getFilePointer

public long getFilePointer()
                    throws IOException

Description copied from interface: ReadOnlyFile

Returns the current byte position in the file as a zero-based index.

Specified by:

getFilePointer in interface ReadOnlyFile

Overrides:

getFilePointer in class DecoratingReadOnlyFile

Throws:

IOException

seek

public void seek(long pos)
          throws IOException

Description copied from interface: ReadOnlyFile

Sets the current byte position in the file as a zero-based index at which the next read occurs. Whether the offset may be set beyond the end of the file is up to the implementor. For example, the DefaultReadOnlyFile subclass RandomAccessFile passes "r" as a parameter to the superclass constructor. With Sun's JSE implementation, on the Windows platform this implementation allows to seek past the end of file, but on the Linux platform it doesn't.

Specified by:

seek in interface ReadOnlyFile

Overrides:

seek in class DecoratingReadOnlyFile

Parameters:

pos - The current byte position as a zero-based index.

Throws:

IOException - If pos is less than 0 or if an I/O error occurs.

read

public int read()
         throws IOException

Description copied from interface: ReadOnlyFile

Reads and returns the next byte or -1 if the end of the file has been reached.

Specified by:

read in interface ReadOnlyFile

Overrides:

read in class DecoratingReadOnlyFile

Throws:

IOException

read

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

Description copied from interface: ReadOnlyFile

Reads up to len bytes of data from this read only file into the given array. This method blocks until at least one byte of input is available.

Specified by:

read in interface ReadOnlyFile

Overrides:

read in class DecoratingReadOnlyFile

Parameters:

b - The buffer to fill with data.

off - The start offset of the data.

len - The maximum number of bytes to read.

Returns:

The total number of bytes read, or -1 if there is no more data because the end of the file has been reached.

Throws:

IOException - On any I/O related issue.

close

public void close()
           throws IOException

Description copied from interface: ReadOnlyFile

Closes this read-only file and releases any non-heap resources allocated for it.

Specified by:

close in interface ReadOnlyFile

Specified by:

close in interface Closeable

Overrides:

close in class DecoratingReadOnlyFile

Throws:

IOException

finalize

protected void finalize()
                 throws Throwable

The finalizer in this class forces this input read only file to close. This ensures that an input target can be updated although the client application may have "forgot" to close this instance before.

Overrides:

finalize in class Object

Throws:

Throwable
