Detailed Description

struct eosio::asset;

Stores information for owner of asset

Public Functions Documentation

function asset

inline asset()

function asset

inline asset(
    int64_t a,
    class symbol s
)

Parameters:

• a - The amount of the asset
• s - The name of the symbol

Construct a new asset given the symbol name and the amount

function is_amount_within_range

inline bool is_amount_within_range() const

Return:

• true - if the amount doesn't exceed the max amount
• false - otherwise

Check if the amount doesn't exceed the max amount

function is_valid

inline bool is_valid() const

Return:

• true - if the asset is valid
• false - otherwise

Check if the asset is valid. A valid asset has its amount <= max_amount and its symbol name valid

function set_amount

inline void set_amount(
    int64_t a
)

Parameters:

• a - New amount for the asset

Set the amount of the asset

function write_as_string

inline char * write_as_string(
    char * begin,
    char * end,
    bool dry_run =false
) const

Writes the asset as a string to the provided char buffer.

Parameters:

• begin - The start of the char buffer
• end - Just past the end of the char buffer
• dry_run - If true, do not actually write anything into the range.

Return: char* - Just past the end of the last character that would be written assuming dry_run == false and end was large enough to provide sufficient space. (Meaning only applies if returned pointer >= begin.)

Precondition:

• is_valid() == true
• The range [begin, end) must be a valid range of memory to write to.

Postcondition: If the output string fits within the range [begin, end) and dry_run == false, the range [begin, returned pointer) contains the string representation of the asset. Nothing is written if dry_run == true or returned pointer > end (insufficient space) or if returned pointer < begin (overflow in calculating desired end).

Writes the asset as a string to the provided char buffer

function to_string

inline std::string to_string() const

asset to std::string

asset to std::string

function print

inline void print() const

Print the asset

Print the asset

Public Attributes Documentation

variable amount

int64_t amount = 0;

The amount of the asset

variable symbol

symbol symbol;

The symbol name of the asset

variable max_amount

static constexpr int64_t max_amount = (1LL << 62) - 1;

Maximum amount possible for this asset. It's capped to 2^62 - 1
