Detailed Description

/* Wraps a uint64_t to ensure it is only passed to methods that expect a name. Ensures value is only passed to methods that expect a name and that no mathematical operations occur. Also enables specialization of print

Enums Documentation

enum raw

enum name::raw {
};

Variables Documentation

variable value

uint64_t eosio::name::value;

variable value

constexpr const char eosio::detail::to_const_char_arr< Str >::value[];

Functions Documentation

function name

constexpr eosio::name::name()

Construct a new name object defaulting to a value of 0.

Construct a new name

function name

explicit constexpr eosio::name::name(
    uint64_t v
)

Construct a new name object initialising value with v.

Construct a new name given a unit64_t value

Parameters:

• v - The unit64_t value

function name

explicit constexpr eosio::name::name(
    name::raw r
)

Construct a new name object initialising value with r.

Construct a new name given a scoped enumerated type of raw (uint64_t).

Parameters:

• r - The raw value which is a scoped enumerated type of unit64_t

function name

explicit constexpr eosio::name::name(
    std::string_view str
)

Construct a new name object initialising value with str.

Construct a new name given an string.

Parameters:

• str - The string value which validated then converted to unit64_t

function char_to_value

static static constexpr uint8_t eosio::name::char_to_value(
    char c
)

Converts a name Base32 symbol into its corresponding value

Parameters:

• c - Character to be converted

Returns:

constexpr char - Converted value

function length

constexpr uint8_t eosio::name::length() const

Returns the length of the name

function suffix

constexpr name eosio::name::suffix() const

Returns the suffix of the name

function operator raw

constexpr eosio::name::operator raw() const

Casts a name to raw

Returns:

Returns an instance of raw based on the value of a name

function operator bool

explicit constexpr eosio::name::operator bool() const

Explicit cast to bool of the uint64_t value of the name

Returns:

Returns true if the name is set to the default value of 0 else true.

function write_as_string

char* eosio::name::write_as_string(
    char * begin,
    char * end
) const

Writes the name as a string to the provided char buffer

Precondition:

Appropriate Size Precondition: (begin + 13) <= end and (begin + 13) does not overflow

Precondition:

Valid Memory Region Precondition: The range [begin, end) must be a valid range of memory to write to.

Parameters:

• begin - The start of the char buffer
• end - Just past the end of the char buffer

Returns:

char* - Just past the end of the last character written (returns begin if the Appropriate Size Precondition is not satisfied)

Post

If the Appropriate Size Precondition is satisfied, the range [begin, returned pointer) contains the string representation of the name.

function to_string

std::string eosio::name::to_string() const

Returns the name value as a string by calling write_as_string() and returning the buffer produced by write_as_string()

Returns the name as a string.
