Functions

int indexCovariance(int i, int j)

Defines the ordering of packed covariance matrices.

This storage is equivalent to LAPACK ‘UPLO=U’.

int computeCovariancePackedSize(int size)

Defines the packed size of a covariance matrices.

struct FlagExtractor

#include <BaseColumnView.h>

Functor to compute a flag bit, used to create an ndarray expression template for flag columns.

struct RecordData

#include <BaseTable.h>

Helper struct that contains the information passed from BaseTable to BaseRecord at construction.

This can’t be a nested class of either of those two classes for dependency reasons, but it should nevertheless be considered opaque by all derived Table and Record classes.

class SchemaImpl

#include <SchemaImpl.h>

A private implementation class to hide the messy details of Schema.

This can’t be a real pimpl class, because some of the most important functionality is in the forEach function, a templated function we can’t explicitly instantiate in a source file. But putting all the details here draws a clear line between what users should look at (Schema) and what they shouldn’t (this).

Because Schema holds SchemaImpl by shared pointer, one SchemaImpl can be shared between multiple Schemas (and SubSchemas), which implement copy-on-write by creating a new SchemaImpl if the pointer they have isn’t unique when they are modified.

class SchemaMapperImpl

#include <SchemaMapperImpl.h>

A private implementation class to hide the messy details of SchemaMapper.

This class is very similar in spirit to SchemaImpl; look there for more information (though SchemaMapper is not copy-on-write).
