IAdjustmentHandler Interface

Definition

Namespace: Bodu.Globalization.Calendar

Assembly: Bodu.Globalization.Calendar.dll

Package: Bodu.Globalization.Calendar 1.0.1

Source: IAdjustmentHandler.cs

Computes the observed date of an occurrence for an adjustment policy whose action is Custom, supplementing the engine's built-in actions with caller-supplied logic.

public interface IAdjustmentHandler

Extension Methods: ComparableExtensions.AtLeast<T>(T, T, IComparer<T>)

ComparableExtensions.AtMost<T>(T, T, IComparer<T>)

ComparableExtensions.IsEqualTo<T>(T, T, IComparer<T>)

ComparableExtensions.Max<T>(T, T, IComparer<T>)

ComparableExtensions.Min<T>(T, T, IComparer<T>)

Examples

// Move the occurrence to the next day that is not already claimed by another non-working date.
public sealed class NextFreeDayHandler : IAdjustmentHandler
{
    public DateOnly? Adjust(AdjustmentHandlerContext context)
    {
        DateOnly date = context.BaseDate;
        while (context.IsOccupied(date))
            date = date.AddDays(1);

        return date == context.BaseDate ? null : date; // null leaves it on the calculated date
    }
}

Remarks

A handler is bound to a policy through the policy's handler key and is consulted during the placement phase, after the actual date has been calculated. It receives the calculated date together with the surrounding resolution context, so it can resolve other rules or test whether candidate days are already claimed by non-working occurrences.
