Parameters:   buffer - the buffer from which the data is appended. Parameters:   off - the start offset of the data in the buffer. Parameters:   len - the number of bytes to append. public  void close()      public  int getFileLength()      public  long getFilePointer()      Returns the current offset in this file. public  void open(boolean requestWrite)      public  void read(byte[] buffer, int off, int len)      Reads up to len bytes of data from this file resource into an array of bytes. public  void resetFile()      public  void seek(long pos)      public  String toString()      Constructor Detail FileAccessor public FileAccessor(File file)(Code) Creates a new instance of FileAccessor Method Detail append public void append(byte[] buffer, int off, int len) throws IOException(Code) Appends exactly len bytes, starting at off of the buffer pointer to the end of file resource. Parameters:   buffer - the buffer from which the data is appended. Parameters:   off - the start offset of the data in the buffer. Parameters:   len - the number of bytes to append. the actual file offset before appending. close public void close() throws IOException(Code) Closes DataAccessor file resource getFileLength public int getFileLength()(Code) getFilePointer public long getFilePointer() throws IOException(Code) Returns the current offset in this file. the offset from the beginning of the file, in bytes,at which the next read or write occurs. open public void open(boolean requestWrite) throws IOException(Code) Opens DataAccessor file resource Parameters:   requestWrite - if true, file is opened for read/write operation. read public void read(byte[] buffer, int off, int len) throws IOException(Code) Reads up to len bytes of data from this file resource into an array of bytes. Parameters:   buffer - the buffer into which the data is read. Parameters:   off - the start offset of the data. Parameters:   len - the maximum number of bytes read. resetFile public void resetFile() throws IOException(Code) Clears the file and sets the offset to 0 seek public void seek(long pos) throws IOException(Code) toString public String toString()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
