LSNativeContext Class¶

class localsolver.LSNativeContext¶

Context for native functions. Native context are used to query the values of the arguments passed to native functions.

Since:	6.0

Summary¶

Methods¶
`count`	Returns the number of values in the current context.
`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_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 context.
`__getitem__`	Returns the value at the given position.

Instance methods¶

LSNativeContext.count()¶: Returns the number of values in the current context.

LSNativeContext.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`

LSNativeContext.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`

LSNativeContext.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`

LSNativeContext.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`

LSNativeContext.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`

LSNativeContext.get(pos)¶

Returns the value at the given position. The returned value can be a double or an integer depending on the type of the value.

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

Special operators and methods¶

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

LSNativeContext.__getitem__(pos)¶

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

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