Detailed Description
Representation of a symbol in GAMS.
A GAMSSymbol exists in a GAMSDatabase and contains GAMSSymbolRecord instances which one can iterate through. Derived classes are GAMSEquation, GAMSParameter, GAMSSet and GAMSVariable.

Member Function Documentation
◆ addRecord()
GAMSSymbolRecord Matlab.GAMS.GAMSSymbol.addRecord | ( | varargin | ) |
Add record to GAMSSymbol.
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 GAMSSymbolRecord
- See also
- GAMSSymbolRecord
Reimplemented in Matlab.GAMS.GAMSEquation, Matlab.GAMS.GAMSParameter, Matlab.GAMS.GAMSSet, and Matlab.GAMS.GAMSVariable.
◆ checkDomains()
logical Matlab.GAMS.GAMSSymbol.checkDomains | ( | ) |
Check domains of all GAMSSymbolRecord instances of the symbol.
Return: true if every instance does not contain a domain violation, false otherwise
- See also
- GAMSSymbolRecord
◆ clear()
logical Matlab.GAMS.GAMSSymbol.clear | ( | ) |
Clear symbol by removing all records of this symbol.
Return: True if cleared successfully, otherwise false
◆ copySymbol()
void Matlab.GAMS.GAMSSymbol.copySymbol | ( | GAMS.GAMSSymbol | target | ) |
Copy all records of this GAMSSymbol to target GAMSSymbol.
Note: If target had records, they will be deleted.
Arguments:
- target: Target GAMSSymbol
◆ deleteRecord()
logical Matlab.GAMS.GAMSSymbol.deleteRecord | ( | varargin | ) |
Delete record from GAMSSymbol.
In case GAMSSymbolRecord T has been successfully deleted, the iteration reference will be reseted as it is no longer possible to iterate to the next symbol using using reference of T.
There are a number of methods to obtain several GAMSSymbolRecord instances with the same underlying data. The behavior of an instance of GAMSSymbolRecord is unspecified if the underlying data has been deleted.
Valid VARARGIN signatures:
- {string key1, ..., string keyN}
- string key1, ..., string keyN
Arguments:
- key1,...,keyN: Keys of record. Empty string is not a valid key.
- See also
- GAMSSymbolRecord
◆ equals()
logical Matlab.GAMS.GAMSSymbol.equals | ( | any | object | ) |
Indicates whether some other object is "equal to" this one.
The two GAMSSymbols are equivalent if and only if they are objects of the same class, same database, same name, same dimension, same explanatory text, and same internal reference.
Arguments:
- object: the reference object with which to compare
Return: true if this object is the same as the obj argument, false otherwise
◆ findRecord()
GAMSSymbolRecord Matlab.GAMS.GAMSSymbol.findRecord | ( | varargin | ) |
Find record in GAMSSymbol.
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 in Matlab.GAMS.GAMSEquation, Matlab.GAMS.GAMSParameter, Matlab.GAMS.GAMSSet, and Matlab.GAMS.GAMSVariable.
◆ getFirstRecord()
GAMSSymbolRecord Matlab.GAMS.GAMSSymbol.getFirstRecord | ( | varargin | ) |
Get the first record of GAMSSymbol.
Retrieve the first record in GAMSSymbol 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 GAMSSymbolRecord found
- See also
- GAMSSymbolRecord
Reimplemented in Matlab.GAMS.GAMSEquation, Matlab.GAMS.GAMSParameter, Matlab.GAMS.GAMSSet, and Matlab.GAMS.GAMSVariable.
◆ getLastRecord()
GAMSSymbolRecord Matlab.GAMS.GAMSSymbol.getLastRecord | ( | varargin | ) |
Get the last record of GAMSSymbol.
Retrieve the first record in GAMSSymbol 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 GAMSSymbolRecord found

- GAMSSymbolRecord
Reimplemented in Matlab.GAMS.GAMSEquation, Matlab.GAMS.GAMSParameter, Matlab.GAMS.GAMSSet, and Matlab.GAMS.GAMSVariable.
◆ getSymbolDomainViolations()
cell Matlab.GAMS.GAMSSymbol.getSymbolDomainViolations | ( | integer | maxNoViolation | ) |
Check domains of all GAMSSymbolRecord instances in the Symbol.
It returns a list of GAMSSymbolDomainViolation instances containing domain violation information for problematic records. Each GAMSSymbolDomainViolation instance contains information of which GAMSSymbolRecord instance whose domain is violated as well as a violation array of boolean value with the size of the GAMSSymbol instance dimension. The array position contains {true} value means there is a domain violation at the relative dimension, otherwise it contains {false} value.
Arguments:
- maxNoViolation: The maximum number of domain violation records which should be stored (0 for no limit)
Return: a list of GAMSDatabaseDomainViolation containing domain violation information
◆ hashCode()
integer Matlab.GAMS.GAMSSymbol.hashCode | ( | ) |
Returns a hash code value for the object.
Return: a hash code value for this object
◆ iterator()
GAMSIterator Matlab.GAMS.GAMSSymbol.iterator | ( | ) |
Returns an iterator over a set of GAMSSymbolRecord instances.
Return: an iterator over a set of GAMSSymbolRecord instances
Reimplemented in Matlab.GAMS.GAMSEquation, Matlab.GAMS.GAMSParameter, Matlab.GAMS.GAMSSet, and Matlab.GAMS.GAMSVariable.
◆ mergeRecord()
GAMSSymbolRecord Matlab.GAMS.GAMSSymbol.mergeRecord | ( | varargin | ) |
Find record with specified keys in GAMSSymbol.
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
Reimplemented in Matlab.GAMS.GAMSEquation, Matlab.GAMS.GAMSParameter, Matlab.GAMS.GAMSSet, and Matlab.GAMS.GAMSVariable.
Member Data Documentation
◆ domainsAsStrings
cell Matlab.GAMS.GAMSSymbol.domainsAsStrings |
(read only) Domains of GAMSSymbol, each element is a string
Note: If the domain is an alias in GAMS, this call will return the name of the alias, not the name of the aliased set
◆ record
GAMSSymbolRecord Matlab.GAMS.GAMSSymbol.record |
(read only) record of GAMSSymbol
If the GAMSSymbol contains multiple records, it points to the first record, but raises a warning. In that case, please use firstRecord.
◆ records
cell Matlab.GAMS.GAMSSymbol.records |
(read only) list of GAMSSymbolRecord instances contained in GAMSSymbol
Performance Note: This cell is created from Java data records for every read. Thus, a loop like
* for i = 1:numel(sym.records) * disp(sym.records{i}.keys); * end *
would create the symbols list numel(sym.records)+1 times. Please use either of the following:
* recs = sym.records; * for i = 1:numel(recs) * disp(sym.records{i}.keys); * end * * for rec = sym.records * disp(rec{1}.keys); * end *
