F# DataReadOnlyCollection
Namespace: Deedle.Internal
Provides helper functions for working with ReadOnlyCollection<T> similar to those
in the Array module. Most importantly, F# 3.0 does not know that array implements
IList<T>.
Functions and values
| Function or value | Description |
empty
Signature: ReadOnlyCollection<'T>
Type parameters: 'T |
Returns empty readonly collection |
fold op init list
Signature: op:('b -> 'T -> 'b) -> init:'b -> list:ReadOnlyCollection<'T> -> 'b
Type parameters: 'b, 'T |
Fold elements of the ReadOnlyCollection |
foldOptional op init list
Signature: op:('b -> 'T -> 'b) -> init:'b -> list:ReadOnlyCollection<OptionalValue<'T>> -> 'b
Type parameters: 'b, 'T |
Fold elements of the ReadOnlyCollection, skipping over missing values |
length(list)
Signature: list:ReadOnlyCollection<'T> -> int
Type parameters: 'T |
Count elements of the ReadOnlyCollection |
map f list
Signature: f:('T -> 'a) -> list:ReadOnlyCollection<'T> -> ReadOnlyCollection<'a>
Type parameters: 'T, 'a |
Transform all elements of ReadOnlyCollection using the specified function |
ofArray(array)
Signature: array:'T [] -> ReadOnlyCollection<'T>
Type parameters: 'T |
Converts an array to ReadOnlyCollection. |
ofSeq(seq)
Signature: seq:seq<'T> -> ReadOnlyCollection<'T>
Type parameters: 'T |
Converts a lazy sequence to fully evaluated ReadOnlyCollection |

Signature: op:('T -> 'T -> 'T) -> list:ReadOnlyCollection<'T> -> 'T
Type parameters: 'T |
Reduce elements of the ReadOnlyCollection |
reduceOptional op list
Signature: op:('T -> 'T -> 'T) -> list:ReadOnlyCollection<OptionalValue<'T>> -> 'T opt
Type parameters: 'T |
