IVector<'T> Type
A generic, typed vector. Represents mapping from addresses to values of type 'T.
The vector provides a minimal interface that is required by series and can be
implemented in a number of ways to provide vector backed by database or an
alternative representation of data.

Description
|
Full Usage:
this.Convert
Parameters:
'T -> 'TNew
arg1 : 'TNew -> 'T
Returns: IVector<'TNew>
Modifiers: abstract |
Create a vector whose values are converted using the specified function, but can be converted back using another specified function. For virtualized vectors, this enables e.g. efficient lookup on the returned vectors (by delegating the lookup to the original source)
|
|
Returns all data of the vector in one of the supported formats. Depending
on the vector, data may be returned as a continuous block of memory using
`ReadOnlyCollection
|
|
Returns value stored in the vector at a specified address.
|
Full Usage:
this.GetValueAtLocation
Parameters:
IVectorLocation
Returns: OptionalValue<'T>
Modifiers: abstract |
Returns value stored in the vector at a specified location. This can typically just call 'GetValue(loc.Address)', but it can do something more clever using the fact that the caller provided us with the address & offset.
|
Full Usage:
this.Select
Parameters:
IVectorLocation -> OptionalValue<'T> -> OptionalValue<'TNew>
Returns: IVector<'TNew>
Modifiers: abstract |
Apply the specified function to all values stored in the vector and return a new vector (not necessarily of the same representation) with the results. The function handles missing values - it is called with optional values and may return a missing value as a result of the transformation.
