LSArray Class¶

class localsolver.LSArray¶

Value type for array expressions.

Such a value is obtained with LSExpression.value when the expression is an array. An array can contain numbers (int, double), other LSArray (for multi-dimensional arrays) or LSCollection (list, set).

Arrays are not decisions and cannot be modified.

Since:	7.5

Summary¶

Methods¶
`count`	Returns the number of values in the collection.
`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_array`	Returns true if the value at the given position is an array.
`get`	Gets the value at the given position.

Special methods¶
`__str__`	Returns a string representation of the values in the array in the format { val0, val1, ..., valN }ReturnsString representation of this array.
`__getitem__`	Operator overloading for LSArray.get().
`__len__`	Returns the length of the array (same result as LSArray.count()).
`__iter__`	Returns an iterator for the content of this array.

Instance methods¶

LSArray.count()¶

Returns the number of values in the collection. Elements in arrays are indexed from 0 to count()-1.

Returns:	Number of values in this LSCollection
Return type:	`int`

LSArray.is_bool(pos)¶

Returns true if the value at the given position is a boolean. You can retrieve the value with get() or with the special overloaded operator __getitem__().

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

LSArray.is_int(pos)¶

Returns true if the value at the given position is an integer. You can retrieve the value with get() or with the special overloaded operator __getitem__().

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

LSArray.is_double(pos)¶

Returns true if the value at the given position is a double. You can retrieve the value with get() or with the special overloaded operator __getitem__().

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

LSArray.is_array(pos)¶

Returns true if the value at the given position is an array. You can retrieve the value with get() or with the special overloaded operator __getitem__().

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

LSArray.get(pos)¶

Gets the value at the given position. The type of the returned value can be a boolean, an integer, a double or a LSArray.

Parameters:	pos (`int`) – Position of the value to query.
Returns:	Value at the given position
Return type:	`bool, int, double or LSArray`

Special operators and methods¶

LSArray.__str__()¶

Returns a string representation of the values in the array in the format { val0, val1, ..., valN }

Returns:	String representation of this array.
Return type:	`str`

LSArray.__getitem__(pos)¶: Operator overloading for LSArray.get().

LSArray.__len__()¶: Returns the length of the array (same result as LSArray.count()).

LSArray.__iter__()¶: Returns an iterator for the content of this array.
