Example 1 with NoSuchDataException

use of org.apache.sis.storage.NoSuchDataException in project sis by apache.

the class AbstractGridResource method canNotRead.

/**
 * Creates an exception for a failure to load data. If the failure may be caused by an envelope
 * outside the resource domain, that envelope will be inferred from the {@code request} argument.
 *
 * @param  filename  some identification (typically a file name) of the data that can not be read.
 * @param  request   the requested domain, or {@code null} if unspecified.
 * @param  cause     the cause of the failure, or {@code null} if none.
 * @return the exception to throw.
