LSExternalArgumentValues Class¶
- class localsolver.LSExternalArgumentValues¶
Argument values for external functions. Argument values are used to query the values of the arguments passed to external functions.
- Since
9.5
- See
LSExternalFunction

Instance methods¶
- LocalSolver GetLocalSolver()¶
Returns the LocalSolver object associated to the argument values.
- Returns
LocalSolver object
- Return type
- bool IsBool(int pos)¶
Returns true if the value at the given position is a boolean. You can retrieve the value with
LSExternalArgumentValues.GetIntValue()
.- Arguments
pos (int) – Position of the value to query.
- Returns
True if the value at the given position is a boolean.
- Return type
bool
- bool IsInt(int pos)¶
Returns true if the value at the given position is an integer. You can retrieve the value with
LSExternalArgumentValues.GetIntValue()
.- Arguments
pos (int) – Position of the value to query.
- Returns
True if the value at the given position is an integer.
- Return type
bool
- bool IsDouble(int pos)¶
Returns true if the value at the given position is a double. You can retrieve the value with
LSExternalArgumentValues.GetDoubleValue()
.- Arguments
pos (int) – Position of the value to query.
- Returns
True if the value at the given position is a double.
- Return type
bool
- bool IsCollection(int pos)¶
Returns true if the value at the given position is a collection (list or set). You can retrieve the value with
LSExternalArgumentValues.GetCollectionValue()
.- Arguments
pos (int) – Position of the value to query.
- Returns
True if the value at the given position is a collection.
- Return type
bool
- bool IsArray(int pos)¶
Returns true if the value at the given position is an array. You can retrieve the value with
LSExternalArgumentValues.GetArrayValue()
.- Arguments
pos (int) – Position of the value to query.
- Returns
True if the value at the given position is an array.
- Return type
bool
- long GetIntValue(int pos)¶
Returns the integer value at the given position. If the value is neither an integer nor a boolean, an exception is thrown.
- Arguments
pos (int) – Position of the value to query.
- Returns
Integer value.
- Return type
long
- double GetDoubleValue(int pos)¶
Returns the double value at the given position. If the value is not a double, an exception is thrown.
- Arguments
pos (int) – Position of the value to query.
- Returns
Double value.
- Return type
double
- LSCollection GetCollectionValue(int pos)¶
Returns the collection value at the given position. If the value is not a collection (list or set), an exception is thrown. Note that the returned collection is read only.
- Arguments
pos (int) – Position of the value to query.
- Returns
Collection value.
- Return type
- LSArray GetArrayValue(int pos)¶
Returns the array value at the given position. If the value is not an array, an exception is thrown.
- Arguments
pos (int) – Position of the value to query.
- Returns
Array value.
- Return type
- int Count()¶
Returns the number of values in the current argument values.
- void CopyTo(long[] values)¶
Copy all the values of the argument values to the given array. Only the integer values are copied to their corresponding position in the array. Cells of the array that correspond to positions of non-integer values in the argument values remain unchanged.
The length of the array can be different from the number of elements in the argument values. In that case, only the elements that fit in the array are copied.
This method is recommended if you need to access all the values of the argument values, instead of the roughly equivalent, but less performant, following code:
for(int i = 0; i < Math.Min(values.Length, argumentValues.Count()); i++) { if(!argumentValues.IsInt(i)) continue; values[i] = argumentValues.GetIntValue(i); }
- Arguments
values (long[]) – Array that will receive the integer values of the argument values.
- void CopyTo(double[] values)
Copy all the values of the argument values to the given array. Only the double values are copied to their corresponding position in the array. Cells of the array that correspond to positions of non-double values in the argument values remain unchanged.
The length of the array can be different from the number of elements in the argument values. In that case, only the elements that fit in the array are copied.
This method is recommended if you need to access all the values of the argument values, instead of the roughly equivalent, but less performant, following code:
for(int i = 0; i < Math.Min(values.Length, argumentValues.Count()); i++) { if(!argumentValues.IsDouble(i)) continue; values[i] = argumentValues.GetDoubleValue(i); }
- Arguments
values (double[]) – Array that will receive the double values of the argument values.
