Namespaces
namespace	OpenMS
	Main OpenMS namespace.
namespace	OpenMS::QPXIdentity
	Opaque QPX row identities (feature_id, psm_id, pg_id)

Typedefs
using	FeatureLinks = std::unordered_map< Int64, Int64 >
	The feature↔PSM edge of one QPX collection, as psm_id → feature_id.
using	Value = std::variant< Null, std::string, Int64, Float32, std::vector< Int32 >, std::vector< std::string > >
	JSON array of strings (grouped_runs)

Functions
std::string	formatFloat (float value)
	Render one float32 the way Python's repr writes it inside JSON.
std::string	canonical (const std::vector< Value > &values, const std::vector< size_t > &unordered_list_indices={})
	Canonical JSON encoding of an identity composite.
Int64	deriveId (const std::vector< Value > &values, const std::vector< size_t > &unordered_list_indices={})
	Derive an opaque signed 64-bit identity from a composite.
Int64	featureId (const std::string &run_file_name, const std::string &peptidoform, Int64 charge, std::optional< float > rt, const std::vector< Int32 > &scan, float observed_mz)
	feature_id from a feature row's persisted column values
Int64	psmId (const std::string &run_file_name, const std::vector< Int32 > &scan, const std::string &peptidoform, Int64 charge)
	psm_id from a psm row's persisted column values
Int64	pgId (const std::vector< std::string > &pg_accessions, const std::vector< std::string > &grouped_runs, const std::optional< std::string > &label)
	pg_id from a protein-group row's persisted column values

Variables
const char *const	FEATURE_COMPOSITE
	Footer identity_composite for the feature view.
const char *const	PSM_COMPOSITE
	Footer identity_composite for the psm view.
const char *const	PG_COMPOSITE
	Footer identity_composite for the pg view.

Class Documentation

OpenMS::QPXIdentity::Null

struct OpenMS::QPXIdentity::Null

A composite component that is JSON null (a null column value)

OpenMS::QPXIdentity::Float32

struct OpenMS::QPXIdentity::Float32

A float32 composite component.

Distinct from double so a caller cannot pass an unrounded value by accident: QPX hashes the value as persisted, so a column stored as float32 must be narrowed to float before it is encoded, whatever precision it was computed at.
