 | IVectorT Interface |
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.

SyntaxThe IVectorT type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | AddressingScheme |
Returns the addressing scheme of the index. When creating a series or a frame
this is compared for equality with the addressing scheme of the vector(s).
(Inherited from IVector.) |
| Data |
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<T>` or as a lazy sequence `seq<T>`.
|
| ElementType |
Returns the type of elements stored in the current vector as `System.Type`.
This member is mainly used for internal purposes (to invoke a generic function
represented by `VectorCallSite1<R>` with the typed version of the current
vector as an argument.
(Inherited from IVector.) |
| Length |
Returns the number of elements in the vector
(Inherited from IVector.) |
| ObjectSequence |
Returns all values of the vector as a sequence of optional objects
(Inherited from IVector.) |
| SuppressPrinting |
When `true`, the formatter in F# Interactive will not attempt to evaluate the
vector to print it. This is useful when the vector contains lazily loaded data.
(Inherited from IVector.) |
Methods| Name | Description | |
|---|---|---|
 | ConvertTNew |
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)
|
| GetObject |
Return value stored in the vector at a specified address. This is simply an
untyped version of `GetValue` method on a typed vector.
(Inherited from IVector.) |
| GetValue |
Returns value stored in the vector at a specified address.
|
| GetValueAtLocation |
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.
|
| InvokeR |
Invokes the specified generic function (vector call site) with the current
instance of vector passed as a statically typed vector (ie. IVector<ElementType>)
(Inherited from IVector.) |
| SelectTNew |
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.
