org.apache.derby.iapi.sql.dictionary.DataDictionary.addDescriptor()
Adds a descriptor to a system catalog identified by the catalogNumber. @param tuple descriptor to insert. @param parent parent descriptor; e.g for a column parent is thetabledescriptor to which the descriptor is beign inserted. for most other objects it is the schema descriptor. @param catalogNumber a value which identifies the catalog into whichthe descriptor should be inserted. It is the users responsibility to ensure that the catalogNumber is consistent with the tuple being inserted. @see DataDictionary#SYSCONGLOMERATES_CATALOG_NUM @param allowsDuplicates whether an exception should be thrown if theinsert results in a duplicate; if this parameter is FALSE then one of the following exception will be thrown; LANG_OBJECT_ALREADY_EXISTS (if parent is null) or LANG_OBJECT_ALREADY_EXISTS_IN_OBJECT (if parent is not null). The error message is created by getting the name and type of the tuple and parent. @see org.apache.derby.impl.sql.catalog.DataDictionaryImpl#duplicateDescriptorException @param tc the transaction controller to use to do all of this. @see #addDescriptorArray
