ParametersBuilder

Class: ParametersBuilder

ParametersBuilder is a helper class to build contract function parameters

Example

const params = new ParametersBuilder()
   .addAddress("0.0.123")
   .addUInt8(42)
   .addBytes32([0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F, 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19, 0x1A, 0x1B, 0x1C, 0x1D, 0x1E, 0x1F])
   .addString("Hello World")
   .addTuple(new ParametersBuilder().addAddress("0.0.456").addUInt8(42))
 ;

encode

Encodes the parameters to a base64 string, compatible with the methods of the BladeSDK

Calling this method is optional, as the BladeSDK will automatically encode the parameters if needed

encode(): string

Returns

string
