Detailed Description
Stores information for owner of asset
Public Attributes Documentation
variable amount
int64_t eosio::asset::amount;
The amount of the asset
variable symbol
symbol eosio::asset::symbol;
The symbol name of the asset
Public Static Attributes Documentation
variable max_amount
constexpr int64_t eosio::asset::max_amount;
Maximum amount possible for this asset. It's capped to 2^62 - 1
Public Functions Documentation
function asset (1/2)
eosio::asset::asset()
function asset (2/2)
eosio::asset::asset(
int64_t a,
class symbol s
)
Construct a new asset given the symbol name and the amount
Parameters:
- a - The amount of the asset
- s - The name of the symbol
function is_amount_within_range
bool eosio::asset::is_amount_within_range() const
Check if the amount doesn't exceed the max amount
Returns:
true - if the amount doesn't exceed the max amount
Returns:
false - otherwise
function is_valid
bool eosio::asset::is_valid() const
Check if the asset is valid. A valid asset has its amount <= max_amount and its symbol name valid
Returns:
true - if the asset is valid
Returns:
false - otherwise
function set_amount
void eosio::asset::set_amount(
int64_t a
)
Set the amount of the asset
Parameters:
- a - New amount for the asset
function write_as_string
char* eosio::asset::write_as_string(
char * begin,
char * end,
bool dry_run = false
) const
Writes the asset as a string to the provided char buffer.
Writes the asset as a string to the provided char buffer
Precondition:
is_valid() == true
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
- dry_run - If true, do not actually write anything into the range.
Returns:
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.)
Post
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).
function to_string
std::string eosio::asset::to_string() const
asset to std::string
asset to std::string
function print
void eosio::asset::print() const
Print the asset
Print the asset
