Type represents trigger type used in C# reference node: https://github.com/neo-project/neo/blob/c64748ecbac3baeb8045b16af0d518398a6ced24/neo/SmartContract/TriggerType.cs#L3

const (
	// The verification trigger indicates that the contract is being invoked as a verification function.
	// The verification function can accept multiple parameters, and should return a boolean value that indicates the validity of the transaction or block.
	// The entry point of the contract will be invoked if the contract is triggered by Verification:
	//     main(...);
	// The entry point of the contract must be able to handle this type of invocation.
	Verification Type = 0x00

	// The verificationR trigger indicates that the contract is being invoked as a verification function because it is specified as a target of an output of the transaction.
	// The verification function accepts no parameter, and should return a boolean value that indicates the validity of the transaction.
	// The entry point of the contract will be invoked if the contract is triggered by VerificationR:
	//     main("receiving", new object[0]);
	//  The receiving function should have the following signature:
	//     public bool receiving()
	//  The receiving function will be invoked automatically when a contract is receiving assets from a transfer.
	VerificationR Type = 0x01

	// The application trigger indicates that the contract is being invoked as an application function.
	// The application function can accept multiple parameters, change the states of the blockchain, and return any type of value.
	// The contract can have any form of entry point, but we recommend that all contracts should have the following entry point:
	//     public byte[] main(string operation, params object[] args)
	// The functions can be invoked by creating an InvocationTransaction.
	Application Type = 0x10

	// The ApplicationR trigger indicates that the default function received of the contract is being invoked because it is specified as a target of an output of the transaction.
	// The received function accepts no parameter, changes the states of the blockchain, and returns any type of value.
	// The entry point of the contract will be invoked if the contract is triggered by ApplicationR:
	//     main("received", new object[0]);
	// The received function should have the following signature:
	//     public byte[] received()
	// The received function will be invoked automatically when a contract is receiving assets from a transfer.
	ApplicationR Type = 0x11
