Detailed Description

Immutable runtime snapshot. Copies share storage; reload replaces a snapshot. Owning lookup handles and decoded results keep old definitions alive.

Definition at line 101 of file decode_database.h.

Constructor & Destructor Documentation

◆ DecodeDatabase()

DecodeDatabase::DecodeDatabase ( const std::vector< DecodeFrame > & frames )

explicit

Copy and validate definitions before building the frame index. Input aliases cannot modify the snapshot, even for rvalue input.

Exceptions

std::invalid_argument for invalid metadata or duplicate keys.

Member Function Documentation

◆ GetFrames()

const std::vector< DecodeFrame > & DecodeDatabase::GetFrames ( ) const

Borrowed view, valid while this snapshot remains alive and unchanged.

Definition at line 115 of file decode_database.cpp.

Referenced by main().

◆ FindFrame()

std::shared_ptr< const DecodeFrame > DecodeDatabase::FindFrame ( const FrameKey & key ) const

Owning handles retain the entire snapshot across reload or destruction.

Definition at line 120 of file decode_database.cpp.

Referenced by FindSignal().

◆ FindFrameByPgn()

PgnLookupResult DecodeDatabase::FindFrameByPgn ( std::uint32_t pgn ) const

Only explicitly marked hasPgn frames participate; ambiguous results have no definition.

References PgnLookupResult::ambiguous, and PgnLookupResult::definition.

◆ FindSignal()

std::shared_ptr< const DecodeSignal > DecodeDatabase::FindSignal ( const SignalKey & key ) const

Return an owning signal handle, or an empty handle for a missing key.
