Instance methods

LocalSolver GetLocalSolver()

Returns the LocalSolver object associated to this context.

Returns:LocalSolver object
Return type:LocalSolver
bool IsBool(int pos)

Returns true if the value at the given position is a boolean. You can retrieve the value with #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 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 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 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
Since:8.5
bool IsArray(int pos)

Returns true if the value at the given position is an array. You can retrieve the value with 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
Since:8.5
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:LSCollection
Since:8.5
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:LSArray
Since:8.5
int Count()

Returns the number of values in the current context.
