Now lets drill down
and explore Symbol tables in more detail. The symbol tables store
SymbolTableRecords such as a LayerTableRecord and LineTypeTableRecord. In the
API all of the SymbolTables have methods, that allow you to add a new record.
They also have an Item property and a Has method that allows you to find if a
SymbolTableRecord already exists in the Symbol Table. The Symbol Table can only contain records
of a certain type. The LayerTable for example can only contain
LayerTableRecords. |
