Class Assert

java.lang.Object

io.fliqa.client.interledger.utils.Assert

public final class Assert
extends Object

Utility class providing assertion methods for input validation.

This class provides a collection of static assertion methods used throughout the Interledger client for validating method parameters and preventing invalid states. All assertion methods throw IllegalArgumentException by default or can accept custom exception suppliers for specific error handling.

Common Usage

 public void processPayment(PaymentPointer wallet, BigDecimal amount) {
     Assert.notNull(wallet, "Wallet cannot be null");
     Assert.isTrue(amount.compareTo(BigDecimal.ZERO) > 0, "Amount must be positive");
 }
