SelectByRange

This is Filter Equivalent. This function may be present in generated code, but should not be used in hand-written code.

Header:	STD.h
Namespace:	fil
Module:	FoundationLite

Selects the elements of the input that fall into the specified range.

Syntax

void fil::SelectByRange
(
	const ftl::Array<Type>& inArray,
	const ftl::Array<float>& inValues,
	ftl::Optional<float> inMinimum,
	ftl::Optional<float> inMaximum,
	ftl::Array<Type>& outSelected
)

Parameters

Name	Type	Default	Description
inArray	const Array<Type>&		Elements to be classified
inValues	const Array<float>&		Corresponding values to be compared against the range
inMinimum	Optional<float>	NIL	Lowest value of the range
inMaximum	Optional<float>	NIL	Highest value of the range
outSelected	Array<Type>&		Array of elements corresponding to values matching the range

Description

The filter accepts an array of objects of type T (decided on filter creation) along with a corresponding array of float values. It selects the objects for which the associated values fit the (inMinimum, inMaximum) range.

Hints

Also consider using the "select" function in formulas.
Before using this filter you need to have an array of objects (to be classified) and an array of feature values that describe the objects.
Connect the array of objects to the inArray input and connect the array of feature values to the inValues input.
Set the range of inMinimum and inMaximum to define the accepted objects.
If you also need to get the arrays of objects that were below or above the range, use the ClassifyByRange filter.

Examples


inArray = {"Alice", "Bill", "Frank", "Patricia", "Thomas"} inValues = {5.0, 4.0, 5.0, 8.0, 6.0} inMinimum = 5.0 inMaximum = 6.0	outSelected = {"Alice", "Frank", "Thomas"}

Errors

List of possible exceptions:

Error type	Description
DomainError	Inconsistent array lengths on input in SelectByRange.
DomainError	Incorrect (NaN) float value on inValues input in SelectByRange.
