Methods

Maximum<TObject, TResult>(IObservable<IChangeSet<TObject>>, Func<TObject, TResult>, TResult)

Continually calculates the maximum value from the underlying data source.

public static IObservable<TResult> Maximum<TObject, TResult>(this IObservable<IChangeSet<TObject>> source, Func<TObject, TResult> valueSelector, TResult emptyValue = default) where TObject : notnull where TResult : struct, IComparable<TResult>

Parameters

source IObservable<IChangeSet<TObject>>

The source.

valueSelector Func<TObject, TResult>

The value selector.

emptyValue TResult

The value to use when the underlying collection is empty.

Returns

IObservable<TResult>

A distinct observable of the maximum item.

Type Parameters

TObject

The type of the object.

TResult

The type of the result.

Maximum<TObject, TKey, TResult>(IObservable<IChangeSet<TObject, TKey>>, Func<TObject, TResult>, TResult)

public static IObservable<TResult> Maximum<TObject, TKey, TResult>(this IObservable<IChangeSet<TObject, TKey>> source, Func<TObject, TResult> valueSelector, TResult emptyValue = default) where TObject : notnull where TKey : notnull where TResult : struct, IComparable<TResult>

Parameters

source IObservable<IChangeSet<TObject, TKey>>

The source.

valueSelector Func<TObject, TResult>

TResult

The type of the result.

Minimum<TObject, TResult>(IObservable<IChangeSet<TObject>>, Func<TObject, TResult>, TResult)

Continually calculates the minimum value from the underlying data source.

public static IObservable<TResult> Minimum<TObject, TResult>(this IObservable<IChangeSet<TObject>> source, Func<TObject, TResult> valueSelector, TResult emptyValue = default) where TObject : notnull where TResult : struct, IComparable<TResult>

Parameters
