registerDecoder<T> method

void registerDecoder<T>(String tableName, RowDecoder<T> decoder, { bool isEvent = false, })

Register a decoder for a table or view.

Creates an empty TableCache for tableName immediately. The cache remains the same instance for the lifetime of this ClientCache, so stream listeners attached before the first server snapshot continue to receive events after data arrives.

Throws ArgumentError if a decoder is already registered for tableName.

Implementation

void registerDecoder<T>(
  String tableName,
  RowDecoder<T> decoder, {
  bool isEvent = false,
}) {
  if (_tables.containsKey(tableName)) {
    throw ArgumentError('Decoder for "$tableName" is already registered');
  }
  if (isEvent) {
    _eventTableNames.add(tableName);
  }
  _tables[tableName] = TableCache<T>(
    tableName: tableName,
    decoder: decoder,
    isEvent: isEvent,
  );
}
