      componentID - id or name for the component

    • removeComponent

      public void removeComponent(JComponent comp)
      Removes the component that is used to resolve conflicts. This method is called by the MergeResolvers when user input is no longer required using the specified component.

      true if the user is being prompted for input.

    • processingCompleted

    • getResolveInformation

      public Object getResolveInformation(String infoType)
      Gets the resolve information object for the indicated standardized name. This is how information is passed between merge managers.
      For example:
      the data type merger knows what data type in the result is equivalent to a given data type from my checked out program. The code unit and function mergers need to be able to get this information so they don't unknowingly re-introduce a data type that was already eliminated by a data type conflict.
      Parameters:
      infoType - the string indicating the type of resolve information
      Returns:
      the object for the named string or null

    • setResolveInformation

      public void setResolveInformation(String infoType, Object infoObject)
      Sets the resolve information object for the indicated standardized name. This is how information is passed between merge managers.
      Specified by:
      setResolveInformation in interface DomainObjectMergeManager
      Parameters:
      infoType - the string indicating the type of resolve information
      infoObject - the object for the named string. This information is determined by the merge manager that creates it.
