      • REPLACE_EMPTY_STRUCTS_OR_RENAME_AND_ADD_HANDLER

        public static final DataTypeConflictHandler REPLACE_EMPTY_STRUCTS_OR_RENAME_AND_ADD_HANDLER
        This conflict handler behaves similar to the DEFAULT_HANDLER with the difference being that a empty composite (see DataType.isNotYetDefined()) will be replaced by a similar non-empty composite type. Alignment (e.g., packing) is not considered when determining conflict resolution.
        For datatypes originating from a source archive with matching ID, the replacment strategy will utilize the implementation with the latest timestamp.
        Unlike the DEFAULT_HANDLER, follow-on dependency datatype resolutions will retain the same conflict resolution strategy.

      • resolveConflict

        public abstract DataTypeConflictHandler.ConflictResult resolveConflict​(DataType addedDataType,
                                                                               DataType existingDataType)
        Callback to handle conflicts in a datatype manager when new datatypes are added that have the same name as an existing datatype. The implementer of this interface should do one of the following: return the addedDataType - which means to replace the existingDataType with the addedDataType (may throw exception if the datatypes are not compatible) return the existingDataType the addedDataType will be ignored and the existing dataType will be used. return a new DataType with a new name/category
        Parameters:
        addedDataType - the datatype being added.
        existingDataType - the datatype that exists with the same name/category as the one added
        Returns:
        an enum specify how to handle the conflict
      • shouldUpdate

        public abstract boolean shouldUpdate​(DataType sourceDataType,
                                             DataType localDataType)
        Callback invoked when an associated dataType is being resolved and its local version of the dataType is different from the source archive's dataType. This method returns true if the local version should be updated to the archive's version of the dataType. Otherwise, the local dataType will be used (without updating) in the resolve operation.
        Parameters:
        sourceDataType -
        localDataType -
        Returns:
        true if the localDataType should be updated to be equivalent to the sourceDataType.
      • getSubsequentHandler

        public abstract DataTypeConflictHandler getSubsequentHandler()
        Returns the appropriate handler for recursive resolve calls.
