Detailed Description

Base Vartable implementation.

Member Function Documentation

contains()

bool wreport::vartable::Base::contains ( Varcode code ) const

overridevirtual

Check if the code can be resolved to a varinfo.

Implements wreport::Vartable.

iterate()

bool wreport::vartable::Base::iterate ( std::function< bool(Varinfo)> dest ) const

overridevirtual

Iterate the whole contents of the table.

Return false from dest to stop iteration.

Returns

true if iteration ended normally, false if dest returned false.

Implements wreport::Vartable.

path()

std::filesystem::path wreport::vartable::Base::path ( ) const

inlineoverridevirtual

Return the pathname of the file from which this table has been loaded.

Implements wreport::Vartable.

References m_pathname.

pathname()

std::string wreport::vartable::Base::pathname ( ) const

inlineoverridevirtual

Return the pathname of the file from which this table has been loaded.

Implements wreport::Vartable.

References m_pathname.

Referenced by wreport::vartable::Bufr::Bufr(), and wreport::vartable::Crex::Crex().

query()

Varinfo wreport::vartable::Base::query ( Varcode code ) const

overridevirtual

Query the Vartable.

Throws an exception if not found.

Parameters

code	wreport::Varcode to query

Returns

the wreport::varinfo with the results of the query.

Implements wreport::Vartable.

query_altered()

Varinfo wreport::vartable::Base::query_altered ( Varcode code, int new_scale, unsigned new_bit_len, int new_bit_ref ) const

overridevirtual

Query an altered version of the vartable.

Parameters

code	wreport::Varcode to query
new_scale	Scale to use instead of the default
new_bit_len	Bit length to use instead of the default
new_bit_ref	bit_ref to use instead of the default

Returns

the wreport::Varinfo with the results of the query. The resulting Varinfo is stored inside the Vartable, can be freely copied around and does not need to be deallocated.

Implements wreport::Vartable.

Field Documentation

entries

std::vector<Entry> wreport::vartable::Base::entries

Entries in this Vartable.

The entries are sorted by varcode, so that we can look them up by binary search.

Since we are handing out pointers to _Varinfo structures inside the vector, those pointers will be invalidated if a vector reallocation gets triggered. This means that once the table has been loaded, it size cannot be changed anymore.
