Key :: assign - Assign typed key string

Implementation overview

• Create copy of key
  Key :: assign ( cKey )
• Create key from string
  Key :: assign ( cString )

Implementation details

1. Create copy of key
   odaba::Key & Key  :: assign ( odaba::Key &cKey )
   

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

   • cKey - Key value

     A key value is the key definition and a value for the key. The key value is typically provided in ESDF format. Other formats might be set (OIF, XML)

2. Create key from string
   odaba::Key & Key  :: assign ( odaba::String &cString )
   

   The function creates a key from the string passed in cString . The string is copied to the key. The string type is determined for the string value. When the string does not correspond to any type, the function throws an exception.

   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).
