Method Summary

byte[]	getData() This method reads bytes form a ACE Resource and stores them into a caller supplied buffer.
int	getData(byte[] b) This method reads bytes form a ACE Resource and stores them into a caller supplied buffer.
long	getTimeStamp() This method return the time that the data resource was last modified
void	writeData(byte[] b) This method writes bytes from the passed array to the data resource

Method Detail

getData

b - The array of bytes to write

Throws:

DataAccessorException - if the Data Resource is not found or the Data Resource is not able to write because of security violation
