示例1: writeVarUInt
/**
* Calculate the size of a variable-length unsigned integer.
*/
writeVarUInt (_value: BigNumber.Value) {
if (!isInteger(_value)) {
throw new Error('UInt must be an integer')
}
let lengthOfValue
if (typeof _value === 'number') {
if (_value < 0) {
throw new Error('UInt must be positive')
}
// Fast path for numbers.
lengthOfValue = getUIntBufferSize(_value)
} else {
// Don't clone an existing BigNumber, since it will not be modified.
const value = BigNumber.isBigNumber(_value) ? _value as BigNumber : new BigNumber(_value)
if (value.isNegative()) {
throw new Error('UInt must be positive')
}
lengthOfValue = getBigUIntBufferSize(value)
}
this.skipVarOctetString(lengthOfValue)
}示例2: if
const mapped = _.map(row, (value: BigNumber | number | null, key: string): Array<any> => {
const previousValue = result[key];
if (sumFields.indexOf(key) === -1 || typeof previousValue === "undefined" || value === null || typeof value === "undefined") {
