Type Name
static constexpr uint8_t char_to_value (char c)

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

Public Functions Documentation

function name (1/4)

constexpr eosio::name::name ()

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

Construct a new name

function name (2/4)

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 (3/4)

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 (4/4)

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 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.

function print

void eosio::name::print () const

Prints an names as base32 encoded string

Parameters:

  • name to be printed

Public Static Functions Documentation

function char_to_value

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
