Examples with ChannelDecoder org.apache.sis.internal.netcdf.impl.ChannelDecoder used on opensource projects

Example 1 with ChannelDecoder

use of org.apache.sis.internal.netcdf.impl.ChannelDecoder in project sis by apache.

the class NetcdfStoreProvider method decoder.

/**
 * Creates a decoder for the given input. This method invokes
 * {@link StorageConnector#closeAllExcept(Object)} after the decoder has been created.
 *
 * @param  listeners  where to send the warnings.
 * @param  connector  information about the input (file, input stream, <i>etc.</i>)
 * @return the decoder for the given input, or {@code null} if the input type is not recognized.
 * @throws IOException if an error occurred while opening the netCDF file.
 * @throws DataStoreException if a logical error (other than I/O) occurred.
