Detailed Description
This is the representation of a symbol in GAMS.
It exists in a GamsDatabase and contains GamsSymbolRecords which one can iterate through. Derived classes are GamsEquation, GamsParameter, GamsSet and GamsVariable.

Property Documentation
◆ domains_as_strings
|
static |
Domains of Symbol, each element is a string.
Note: If the domains is as alias in GAMS, this call will return the name of the alias, not the name of the aliased set
◆ number_records
|
static |
Retrieve the number of records of the GamsSymbol.
- Note
- This is the same as calling len(symbol)
