Member Function Documentation
◆ addRecord()
| gams.control.EquationRecord matlab.gams.control.Equation.addRecord | ( | varargin | ) |
Add record to Symbol.
Valid VARARGIN signatures:
- {string key1, ..., string keyN}
- string key1, ..., string keyN
Arguments:
- key1,...,keyN: Keys of record. Empty string is not a valid key.
Return: instance of SymbolRecord
- See also
- SymbolRecord
Reimplemented from matlab.gams.control.Symbol.
◆ findRecord()
| gams.control.EquationRecord matlab.gams.control.Equation.findRecord | ( | varargin | ) |
Find record in Symbol.
Valid VARARGIN signatures:
- {string key1, ..., string keyN}
- string key1, ..., string keyN
Arguments:
- key1,...,keyN: Keys of record. Empty string is not a valid key.
Reimplemented from matlab.gams.control.Symbol.
◆ getFirstRecord()
| gams.control.EquationRecord matlab.gams.control.Equation.getFirstRecord | ( | varargin | ) |
Get the first record of Symbol.
Retrieve the first record in Symbol that meets the slice criteria. For example:
* try
* fprintf('Transportation costs to chicago\n');
* slice = {' ', 'chicago'};
* c = t1.outDB.getParameter('c');
* x1 = c.getFirstRecord(slice);
* while true
* fprintf('from %s to %s\n', x1.key(1), x1.key(2));
* if ~x1.moveNext()
* break;
* end
* end
* catch
* fprintf('No records found\n');
* end
* Valid VARARGIN signatures:
- {string slice1, ..., string sliceN}
- string slice1, ..., string sliceN
Arguments:
- slice1,...,sliceN: Define filter for elements whose record should be retrieved
Return: instance of first SymbolRecord found
- See also
- SymbolRecord
Reimplemented from matlab.gams.control.Symbol.
◆ getLastRecord()
| gams.control.EquationRecord matlab.gams.control.Equation.getLastRecord | ( | varargin | ) |
Get the last record of Symbol.
Retrieve the first record in Symbol that meets the slice criteria.
Valid VARARGIN signatures:
- {string slice1, ..., string sliceN}
- string slice1, ..., string sliceN
Arguments:
- slice1,...,sliceN: Define filter for elements whose record should be retrieved
Return: instance of first SymbolRecord found
- See also
- SymbolRecord
Reimplemented from matlab.gams.control.Symbol.
◆ iterator()
| Iterator matlab.gams.control.Equation.iterator | ( | ) |
Returns an iterator over a set of SymbolRecord instances.
Return: an iterator over a set of SymbolRecord instances
Reimplemented from matlab.gams.control.Symbol.
◆ mergeRecord()
| gams.control.EquationRecord matlab.gams.control.Equation.mergeRecord | ( | varargin | ) |
Find record with specified keys in Symbol.
In case the record is not found, the record with the specified keys will be added and returned the call.
Valid VARARGIN signatures:
- {string key1, ..., string keyN}
- string key1, ..., string keyN
Arguments:
- key1,...,keyN: Keys of record. Empty string is not a valid key.
Return: Reference to record that is found or added
