IDataFrameSchema Interface

Provides key-independent inspection of a data frame schema.

Definition

Namespace: Numerics.NET.DataAnalysis.Schema
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 10.8.0
C# 
public interface IDataFrameSchema

Remarks

This interface exposes only members that do not require constructing or accepting values of the typed column-key type. Use DataFrameSchema<R, C> when typed column-key lookup is required.

Schema objects are read-only snapshots. Inspecting a schema never mutates the data frame or dataframe-owned metadata from which the schema was derived.

Properties

ColumnCount Gets the number of columns described by the schema snapshot.
ColumnIndex Gets the non-generic column index for ordinal and runtime inspection.
Columns Gets the ordered, non-generic column schemas.
Item Gets the column schema at the specified ordinal.

Methods

GetColumnAt Gets the column schema at the specified ordinal.
