# SetIndicators(IEnumerable, Func, Func, Func) Method

Add indicator constraints to this model. The function iterates through data and calls the provided functions for each element found. The return values of the functions are used to construct an indicator constraint. For a fixed t, if IndicatorValue(t) returns true then the created constraint states that if IndicatorVariable(t) is 1 (one), then Row(t) must be satisfied and is ignored otherwise. Otherwise, Row(t) must be satisfied if IndicatorVariable(t) is 0 (zero) and is ignored otherwise. All referenced variables and rows must exist.

Syntax
C#

    public void SetIndicators<T>(
    	IEnumerable<T> data,
    	Func<T, Variable> indicatorVariable,
    	Func<T, bool> indicatorValue,
    	Func<T, Inequality> row
    )

#### Parameters

data IEnumerable T
  Data for which constraints are created.
indicatorVariable Func T, Variable
  Indicator variables.
indicatorValue Func T, Boolean
  Whether indicator variables should be non-zero or zero for rows to become active. If this is null then rows become active if indicator variables are non-zero.
row Func T, Inequality
  The implied rows for the indicator constraints.

#### Type Parameters

T
  Data type.
