Update<T,TArg>(ImmutableArray<T>, Func<ImmutableArray<T>,TArg,ImmutableArray<T>>, TArg)

Mutates an immutable array in-place with optimistic locking transaction semantics via a specified transformation function. The transformation is retried as many times as necessary to win the optimistic locking race.
Update<T,TArg>(T, Func<T,TArg,T>, TArg)

Mutates a value in-place with optimistic locking transaction semantics via a specified transformation function. The transformation is retried as many times as necessary to win the optimistic locking race.
Update<T>(ImmutableArray<T>, Func<ImmutableArray<T>,ImmutableArray<T>>)

Mutates an immutable array in-place with optimistic locking transaction semantics via a specified transformation function. The transformation is retried as many times as necessary to win the optimistic locking race.
Update<T>(T, Func<T,T>)

Mutates a value in-place with optimistic locking transaction semantics via a specified transformation function. The transformation is retried as many times as necessary to win the optimistic locking race.

Mutates an immutable array in-place with optimistic locking transaction semantics via a specified transformation function. The transformation is retried as many times as necessary to win the optimistic locking race.

public:
generic <typename T, typename TArg>
 static bool Update(System::Collections::Immutable::ImmutableArray<T> % location, Func<System::Collections::Immutable::ImmutableArray<T>, TArg, System::Collections::Immutable::ImmutableArray<T>> ^ transformer, TArg transformerArgument);
public static bool Update<T,TArg> (ref System.Collections.Immutable.ImmutableArray<T> location, Func<System.Collections.Immutable.ImmutableArray<T>,TArg,System.Collections.Immutable.ImmutableArray<T>> transformer, TArg transformerArgument);
static member Update : ImmutableArray * Func<System.Collections.Immutable.ImmutableArray<'T>, 'Arg, System.Collections.Immutable.ImmutableArray<'T>> * 'Arg -> bool
Public Shared Function Update(Of T, TArg) (ByRef location As ImmutableArray(Of T), transformer As Func(Of ImmutableArray(Of T), TArg, ImmutableArray(Of T)), transformerArgument As TArg) As Boolean

Type Parameters

T

The type of data in the immutable array.

TArg

The type of argument passed to the transformer.

Parameters

location
ImmutableArray<T>

The immutable array to be changed.

transformer
Func<ImmutableArray<T>,TArg,ImmutableArray<T>>

A function that produces the new array from the old. This function should be side-effect free, as it may run multiple times when races occur with other threads.

transformerArgument
TArg

The argument to pass to transformer.

Returns

Boolean

true if the location's value is changed by applying the result of the transformer function; false if the location's value remained the same because the last invocation of transformer returned the existing value.

Applies to

Type Parameters

T

The type of data.

TArg

The type of argument passed to the transformer.

Parameters

location
T

The variable or field to be changed, which may be accessed by multiple threads.

transformer
Func<T,TArg,T>

A function that mutates the value. This function should be side-effect free, as it may run multiple times when races occur with other threads.

transformerArgument
TArg

The argument to pass to transformer.

Returns

Boolean

true if the location's value is changed by applying the result of the transformer function; false if the location's value remained the same because the last invocation of transformer returned the existing value.
