violation-builder

A small java library for building violations.

Usage samples

void example() throws ViolationException {
  boolean condition = true;

  ViolationBuilder.builder()
    .error(condition,"error-key", () -> "some error message.")
    .warning(condition,"waring-key", () -> "some warning message.")
    .buildIgnoreWarnings();
}

Appends to the builder a violations of error type.

void example() throws ViolationException {
  boolean condition = true;

  ViolationBuilder.builder()
    .error(condition, "error-key-01", "some error-01 message.")
    .error("error-key-02", "some error-02 message.")
    .error(condition,"error-key-03", () -> "some error-03 message.")
    .error("error-key-04", () -> "some error-04 message.")
    .build();
}

Appends to the builder a violations of warning type.

void example() throws ViolationException {
  boolean condition = true;

  ViolationBuilder.builder()
    .warning(condition, "waring-key-01", "some waring-01 message.")
    .warning("waring-key-02", "some waring-02 message.")
    .warning(condition,"waring-key-03", () -> "some warning-03 message.")
    .warning("waring-key-04", () -> "some warning-04 message.")
    .build();
}

Executing a collection of validation rules

final Collection<ValidationRule<Object>> rules = Arrays.asList(
  new ValidationRuleContinueFlow<Object>() {
    @Override
    public void runContinueFlow(ViolationBuilder violationBuilder, Object data) {
      violationBuilder.warning(/* validation on the data */, "waring-key-01", "some waring-01 message.");
    }
  },
  new ValidationRuleStopFlow<Object>() {
    @Override
    public void runStopFlow(ViolationBuilder violationBuilder, Object data) {
      violationBuilder.error(/* validation on the data */, "error-key-01", "some error-01 message.");
    }
  },
  new ValidationRuleContinueFlow<Object>() {
    @Override
    public void runContinueFlow(ViolationBuilder violationBuilder, Object data) {
      violationBuilder.error(/* validation on the data */, "error-key-02", "some error-02 message.");
    }
  },
  new ValidationRule<Object>() {
    @Override
    public Rulesflow run(ViolationBuilder violationBuilder, Object data) {
      violationBuilder.error(/* validation on the data */, "error-key-03", "some error-03 message.");
      return Rulesflow.CONTINUE;
    }
  }
);

RulesExecutor.rulesExecutor(rules, data);
