Instance :: Instance - Instance constructor

The instance constructor provides several conversion functions in order to convert different string formats into instance values. When creating an instance by passing a string value, the string type is determined from the string value.

Implementation overview

Implementation details

  1. Copy instance
    Instance  :: Instance ( odaba::Instance &cInstance )

    The function duplicates the string value and the type definition from the typed string passed in cInstance . When the type definition is valid, the string will be converted into an internal instance.

    • cInstance - Instance

      The instance is passed as String, which is structured as ESDF data (object interchange format).

  3. Create instance from string value
    Instance  :: Instance ( odaba::String &cString )

    The function creates an instance from the string passed in cString . The string is copied to the instance. The string value is not validated when creating the type string, but will be validated later on, when applying to a complex data type.

    • cString - Constant string object

      When iPosition exceeds the string length or when the string is empty, the the function returns -1 (lower).

  4. - internal feature (not documented)
    Instance  :: Instance ( odaba::TypeDefinition &cTypeDefinition )
    • cTypeDefinition - Type definition

      Type definition refers to a type descriptor for a complex data type (structure), view or enumeration.
