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

Example 1 with Decoder

use of org.apache.sis.internal.netcdf.Decoder in project sis by apache.

the class MetadataReaderTest method testEmbedded.

/**
 * Reads the metadata using the netCDF decoder embedded with SIS,
 * and compares its string representation with the expected one.
 *
 * @throws IOException if an I/O error occurred while opening the file.
 * @throws DataStoreException if a logical error occurred.
 */

    try (Decoder input = ChannelDecoderTest.createChannelDecoder(NCEP)) {
        metadata = new MetadataReader(input).read();
    }
    compareToExpected(metadata);
}

Example 2 with Decoder

use of org.apache.sis.internal.netcdf.Decoder 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.

Example 3 with Decoder

use of org.apache.sis.internal.netcdf.Decoder in project sis by apache.

the class MetadataReaderTest method testUCAR.

/**
 * Reads the metadata using the UCAR library and compares
 * its string representation with the expected one.
 *
 * @throws IOException if an I/O error occurred.
 * @throws DataStoreException if a logical error occurred.
