Namespace: Deedle.Vectors.Virtual
Assembly: Deedle.dll

Module that implements various helper operations over `IVirtualVectorSource` type

Types

Type	Description
IBoxedVectorSource<'T>	Marks IVirtualVectorSource that has been created by boxing another source
ICombinedVectorSource<'T>	Marks IVirtualVectorSource that has been created by combining another sources
IMappedVectorSource<'T, 'R>	Marks IVirtualVectorSource that has been created by mapping from source

Functions and values

Function or value	Description
`boxSource source` Full Usage: `boxSource source` Parameters: source : `IVirtualVectorSource<'T>` Returns: `IVirtualVectorSource<obj>`	Creates a new vector source that boxes all values The result also implements IBoxedVectorSource source : `IVirtualVectorSource<'T>` Returns: `IVirtualVectorSource<obj>`
`combine f sources` Full Usage: `combine f sources` Parameters: f : `OptionalValue<'T> list -> OptionalValue<'R>` sources : `IVirtualVectorSource<'T> list` Returns: `IVirtualVectorSource<'R>`	Creates a new vector that combines (zips) vectors using a given function The result also implements ICombinedVectorSource f : `OptionalValue<'T> list -> OptionalValue<'R>` sources : `IVirtualVectorSource<'T> list` Returns: `IVirtualVectorSource<'R>`
`createRowReader vectorCtor builder irt vectors sources` Full Usage: `createRowReader vectorCtor builder irt vectors sources` Parameters: vectorCtor : `IVirtualVectorSource<'T> -> IVector` builder : `IVectorBuilder` irt : `IRowReaderTransform` vectors : `IVector<IVector>` sources : `IVirtualVectorSource<'T> list` Returns: `IVirtualVectorSource<IVector<obj>>`	Creates a "row reader vector" - that is a vector that provides source for the series returned by frame.Rows. This is combined from a number of sources, but we do not fully materialize anything to create the vector. The first parameter is a ctor for `VirtualVector` which is defined below in the file. vectorCtor : `IVirtualVectorSource<'T> -> IVector` builder : `IVectorBuilder` irt : `IRowReaderTransform` vectors : `IVector<IVector>` sources : `IVirtualVectorSource<'T> list` Returns: `IVirtualVectorSource<IVector<obj>>`
`map rev f source` Full Usage: `map rev f source` Parameters: rev : `('TNew -> 'V) option` f : `IVectorLocation -> OptionalValue<'V> -> OptionalValue<'TNew>` source : `IVirtualVectorSource<'V>` Returns: `IVirtualVectorSource<'TNew>`	Creates a new vector that transforms source values using a given function The result also implements IMappedVectorSource rev : `('TNew -> 'V) option` f : `IVectorLocation -> OptionalValue<'V> -> OptionalValue<'TNew>` source : `IVirtualVectorSource<'V>` Returns: `IVirtualVectorSource<'TNew>`
