Bug 876

Documentation says it only applies to StructType, but this is strictly not the case. It should also be expanded to include unions.

For IDL code:
  struct RushIdent
    {
    long long first ;
    long long second ;
    } ;

  struct PositionData
    {
    FormatCode format ;
    long poolID ;
    long long poolFrame ;
    short skew ;
    RushIdent rushID ;
    long rushFrame ;
    } ;

  union ServerFragmentData switch (FragmentType)
    {
    case videoFragment:
      PositionData videoFragmentData ;
    // lots more
    } ;

  struct ServerFragment
    {
    long trackNum  ;
    long start ;
    long finish ;
    ServerFragmentData fragmentData ;
    } ;


Test code:
    RushIdent rid = new RushIdent () ;
    rid.first = 1 ;
    rid.second = 2 ;

    PositionData pd = new PositionData () ;
    pd.format = 1 ;
    pd.poolFrame = 2 ;
    pd.poolID = 3 ;
    pd.rushFrame = 4 ;
    pd.skew = 5 ;
    pd.rushID = rid ;

    ServerFragmentData sfd = new ServerFragmentData () ;
    sfd.videoFragmentData (pd) ;

    ServerFragment sf = new ServerFragment () ;
    sf.start = 10 ;
    sf.finish = 20 ;
    sf.trackNum = 1 ;
    sf.fragmentData = sfd ;

    System.out.println ("---------") ;
    System.out.println ("sf=" + sf) ;
    System.out.println ("---------") ;
    System.out.println ("sfd=" + sfd) ;
    System.out.println ("---------") ;
    System.out.println ("pd=" + pd) ;
    System.out.println ("---------") ;
    System.out.println ("rid=" + rid) ;
    System.out.println ("---------") ;

output:
---------
sf=com.company.project.ServerFragment@1d5e499
---------
sfd=com.company.project.ServerFragmentData@19302fb
---------
pd=com.company.project.PositionData@a8cd58
---------
rid=com.company.project.RushIdent@4173b9
---------

output with -genEnhanced
---------

int trackNum=1,
int start=10,
int finish=20,
com.company.project.ServerFragmentData fragmentData=com.company.project.ServerFragmentData@16c03ee
}

int poolID=3,

com.company.project.RushIdent rushID=struct com.company.project.RushIdent {
long first=1,
long second=2
},
int rushFrame=4
}
---------
rid=struct com.company.project.RushIdent {
long first=1,
long second=2
}

I hope you can see that the output from ServerFragment and ServerFragmentData is useless. Their toString methods should cascade down calling toString on all contained IDL generated objects.
As a developer I still have to inspect all the sub parts myself and write my own toString methods which contain IDL types.

The "union".toString() should look at the discriminator and call toString on the contained object.
