示例1: isValidMemoId
/**
* Return boolean indicating whether a memo id is valid
*
* @param memoId {String} memo id
* @returns {boolean} true if memo id is valid
*/
isValidMemoId(memoId) {
try {
stellar.Memo.id(memoId); // throws if the value is not valid memo id
memoId = new BigNumber(memoId);
} catch (e) {
return false;
}
return (memoId.gte(0) && memoId.lt(maxMemoId));
}示例2: isValidMemo
/**
* Evaluates whether a memo is valid
*
* @param value {String} value of the memo
* @param type {String} type of the memo
* @returns {Boolean} true if value and type are a valid
*/
isValidMemo({ value, type }) {
if (!value || !type) {
return false;
}
try {
// throws if the value is not valid for the type
// valid types are: 'id', 'text', 'hash', 'return'
// See https://www.stellar.org/developers/guides/concepts/transactions.html#memo
stellar.Memo[type](value);
} catch (e) {
return false;
}
return true;
