The custom Streamer for this table

TTableDescriptor(TClass *classPtr)
: TTable("tableDescriptor",sizeof(tableDescriptor_st)),fRowClass(0),fSecondDescriptor(0)
Create a descriptor of the C-structure defined by TClass
TClass *classPtr must be a valid pointer to TClass object for
"plain" C_struture only !!!
void Init(TClass *classPtr)
Create a descriptor of the C-structure defined by TClass
TClass *classPtr must be a valid pointer to TClass object for
"plain" C_structure only !!!
~TTableDescriptor()
TString CreateLeafList() const
Create a list of leaf to be useful for TBranch::TBranch ctor
TTableDescriptor* MakeDescriptor(const char *structName)
MakeDescriptor(const char *structName) - static method
structName - the name of the C structure
to create descriptor of
return a new instance of the TTableDescriptor or 0
if the "structName is not present with the dictionary
void LearnTable(const TTable *parentTable)
void LearnTable(TClass *classPtr)
LearnTable() creates an array of the descriptors for elements of the row
It creates a descriptor of the C-structure defined by TClass
TClass *classPtr must be a valid pointer to TClass object for
"plain" C-structure only !!!
This is to introduce an artificial restriction demanded by STAR database group
1. the name may be 31 symbols at most
2. the number the dimension is 3 at most
To lift this restriction one has to provide -DNORESTRICTIONS CPP symbol and
recompile code (and debug code NOW!)
Int_t UpdateOffsets(const TTableDescriptor *newDescriptor)
"Schema evolution"
Method updates the offsets with a new ones from another descriptor
const Int_t ColumnByName(const Char_t *columnName) const
Find the column index but the column name
Int_t Offset(const Char_t *columnName) const
Return offset of the column defined by "columnName"
Take in account index if provided
Can not handle multidimensional indeces yet.
Int_t ColumnSize(const Char_t *columnName) const
Int_t TypeSize(const Char_t *columnName) const
Int_t Dimensions(const Char_t *columnName) const
