Classes
struct	fcb::AttributeIndexInfo
	One attribute column's B+tree index metadata, as recorded in the header (AttributeIndex, header.fbs). More...
struct	fcb::HeaderWriterOptions
	Configuration for header writing. More...
struct	fcb::ParsedReferenceSystem
	A metadata.referenceSystem URL, parsed into its OGC three-element form. More...
struct	fcb::PocOffsets
	Builds the pointOfContact fields of a header from CityJSON metadata.pointOfContact. More...

Functions
::Transform	fcb::to_transform (const nlohmann::ordered_json &transform)
	Builds the Transform struct (scale + translate) from CityJSON's top-level transform member.
std::optional< ParsedReferenceSystem >	fcb::parse_reference_system (const std::string &url)
	Parses a referenceSystem URL (https://www.opengis.net/def/crs/{authority}/{version}/{code}, per cjseq2's ReferenceSystem::from_url) into its three OGC elements.
::flatbuffers::Offset<::ReferenceSystem >	fcb::to_reference_system (::flatbuffers::FlatBufferBuilder &fbb, const ParsedReferenceSystem &ref_sys)
	Builds the ReferenceSystem table from a parsed metadata.referenceSystem URL.
::flatbuffers::Offset<::Extension >	fcb::to_extension (::flatbuffers::FlatBufferBuilder &fbb, const std::string &name, const std::string &url, const std::string &version)
	Builds one extensions entry: only name/url/version are written (the schema document itself is never fetched or embedded).
::flatbuffers::Offset<::flatbuffers::Vector< const ::DoubleVertex * > >	fcb::to_templates_vertices (::flatbuffers::FlatBufferBuilder &fbb, const nlohmann::ordered_json &vertices_templates)
	Builds Header.templates_vertices from CityJSON's geometry-templates.vertices-templates (f64 precision, unlike a feature's own int32 vertices).
PocOffsets	fcb::to_point_of_contact (::flatbuffers::FlatBufferBuilder &fbb, const nlohmann::ordered_json &poc)
::flatbuffers::Offset<::Header >	fcb::to_fcb_header (::flatbuffers::FlatBufferBuilder &fbb, const nlohmann::ordered_json &cj, const HeaderWriterOptions &options, const AttributeSchema &attr_schema, const AttributeSchema *semantic_attr_schema, const std::vector< AttributeIndexInfo > *attribute_indices_info)
	Builds the whole Header table from the CityJSON metadata line (the first line of a CityJSONSeq: type/version/transform/metadata/ geometry-templates/appearance/extensions), the writer options, and the attribute schema(s).
