Code: SetFromNode
Prefix:
//
// Make sure the formats stored in the data node are valid
// before we attempt to use the data from them.
//
ValidateFormats(searchNode);
Postfix:
Function: ValidateFormats
Declaration: void ValidateFormats(DataNode *);
Definition:
// ****************************************************************************
// Method: MovieAttributes::ValidateFormats
//
// Purpose:
// This method looks at the formats stored in the DataNode and modifies them
// as required to ensure they are all the same length.
