Namespace:
Microsoft.Data.Analysis
Assembly:
Microsoft.Data.Analysis.dll
Package:
Microsoft.Data.Analysis v0.21.1

Returns an enumeration of immutable ReadOnlyMemory<T> buffers representing null values in the Apache Arrow format

Public Iterator Function GetReadOnlyNullBitMapBuffers () As IEnumerable(Of ReadOnlyMemory(Of Byte))

Returns

IEnumerable<ReadOnlyMemory<Byte>>

An enumeration of ReadOnlyMemory<T> objects whose elements encode the null bit maps for the column's values

Attributes
IteratorStateMachineAttribute

Remarks

Each ReadOnlyMemory<T> encodes the indices of null values in its corresponding Data buffer
