Function Documentation

normalize_key()

std::string normalize_key ( std::string_view  s )

inline

Normalizes a string key in a case-insensitive manner.

The current implementation:

• lowercases all characters using std::tolower,
• preserves all characters (alphanumeric and others).

Optionally, the commented-out line can be enabled to ignore characters that are not alphanumeric (such as spaces or punctuation).

Parameters

s	Input string view to normalize.

Returns

Lowercased std::string, suitable for use as a canonical key.

operator<()

template<class Tag >

bool operator< ( const SymbolId< Tag > &  a, const SymbolId< Tag > &  b  )

inlinenoexcept

Case-insensitive strict ordering for SymbolId<Tag>.

The ordering is defined by lexicographic comparison of the normalized names (see normalize_key()). This allows SymbolId<Tag> to be used as keys in ordered containers if needed.

Template Parameters

Tag	Tag type of the SymbolId.

Parameters

a	First identifier.
b	Second identifier.

Returns

true if the normalized name of a is lexicographically smaller than that of b.

Definition at line 137 of file dynamic_registry.h.

operator==()

template<class Tag >

bool operator== ( const SymbolId< Tag > &  a, const SymbolId< Tag > &  b  )

inlinenoexcept

Case-insensitive equality comparison for SymbolId<Tag>.

Two SymbolId<Tag> values are considered equal if their normalized names (as returned by normalize_key()) are equal, independently of original case.

Template Parameters

Tag	Tag type of the SymbolId.

Parameters

a	First identifier.
b	Second identifier.

Returns

true if both identifiers are equal under normalization.
