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

Summary¶

Methods¶
`count`	Returns the number of values in the current argument values.
`is_bool`	Returns true if the value at the given position is a boolean.
`is_int`	Returns true if the value at the given position is an integer.
`is_double`	Returns true if the value at the given position is a double.
`is_interval`	Returns true if the value at the given position is an interval.
`is_collection`	Returns true if the value at the given position is a collection (list or set).
`is_array`	Returns true if the value at the given position is an array.
`get`	Returns the value at the given position.

Special methods¶
`__len__`	Returns the number of values in the current argument values.
`__getitem__`	Returns the value at the given position.

Instance methods¶

LSExternalArgumentValues.count()¶: Returns the number of values in the current argument values.

LSExternalArgumentValues.is_bool(pos)¶

Returns true if the value at the given position is a boolean. You can retrieve the value with get().

Parameters: pos – Position of the value to query.
Returns: True if the value at the given position is a boolean.
Return type: bool

LSExternalArgumentValues.is_int(pos)¶

Returns true if the value at the given position is an integer. You can retrieve the value with get().

Parameters: pos – Position of the value to query.
Returns: True if the value at the given position is an integer.
Return type: bool

LSExternalArgumentValues.is_double(pos)¶

Returns true if the value at the given position is a double. You can retrieve the value with get().

Parameters: pos – Position of the value to query.
Returns: True if the value at the given position is a double.
Return type: bool

LSExternalArgumentValues.is_interval(pos)¶

Returns true if the value at the given position is an interval. You can retrieve the value with get().

Parameters: pos – Position of the value to query.
Returns: True if the value at the given position is an interval.
Return type: bool

LSExternalArgumentValues.is_collection(pos)¶

Returns true if the value at the given position is a collection (list or set). You can retrieve the value with get().

Parameters: pos – Position of the value to query.
Returns: True if the value at the given position is an array.
Return type: bool

LSExternalArgumentValues.is_array(pos)¶

Returns true if the value at the given position is an array. You can retrieve the value with get().

Parameters: pos – Position of the value to query.
Returns: True if the value at the given position is an array.
Return type: bool

LSExternalArgumentValues.get(pos)¶

Returns the value at the given position. The returned value can be a boolean, an integer, a double, a LSInterval, a LSCollection or a LSArray.

Parameters: pos – Position of the value to query.
Returns: Value
Return type: bool, int, double, LSInterval, LSCollection or LSArray

Special operators and methods¶

LSExternalArgumentValues.__len__()¶: Returns the number of values in the current argument values. This method allows users to call len() function directly on the external argument values without using the count() method.

LSExternalArgumentValues.__getitem__(pos)¶

Returns the value at the given position. This method allows users to use [] operator directly on the external argument values without using the get() method.

Parameters: pos – Position of the value to query.
Returns: Value
Return type: int, double, LSArray or LSCollection
