Class StringView¶

Defined in File StringView.hpp

Class Documentation¶

class StringView¶ [source]

Non-owning, read-only view of a NUL-terminated string.

The referenced data must outlive the view. Construction from a const char* or a String is implicit so that existing call sites require no changes when a function parameter is widened from const String& to StringView.

Public Functions

StringView(const char *str)¶: Construct from a NUL-terminated C string.

StringView(const char *str, size_t len)¶: Construct from a pointer and an explicit length.

StringView(const String &str)¶: Construct from a String (caller must ensure lifetime).

inline const char *data() const¶: Pointer to the character data.

inline const char *c_str() const¶: NUL-terminated pointer to the character data.

inline size_t size() const¶: Number of characters (not counting the NUL terminator).

inline bool empty() const¶: True if the view has zero characters.

inline const char &operator[](size_t pos) const¶: Access the character at pos (unchecked).
