GAB-Validate

The GAB Studios Validation Library for Java. The purpose of this project is to analyze and examine how I would create a validation library for Java. Comments are welcome. Thank you.

Maven Dependency

Build

Use Maven to build - mvn package.

Required

This project requires the following:

* Java 8, 11
* Maven

Usage

In order to validate, you need to call a defineXXXXXX() method Validate.defineString("HelloWorld"). Once that is done, you can perform tests by chain calling test methods.

Validate.defineString("HelloWorld").testMaxLength(10).throwValidationExceptionOnFail().validate();

boolean retVal = Validate.defineInteger(5000).testMaxValue(max).testMinValue(min).validate();

Example

To validate a Boolean:

   Validate.defineBoolean(name != null && name.length() > 0)
           .testTrue()
           .throwValidationExceptionOnFail()
           .validate();

    boolean retVal = Validate.defineBoolean(name != null && name.length() > 0)
                             .testTrue()
                             .validate();

To validate a String:

   Validate.defineString("HelloWorld").testEqualsNoCase("hELLOwORLD")
           .testMaxLength(10)
           .throwValidationExceptionOnFail()
           .validate();

   boolean retVal = Validate.defineString("HelloWorld")
                            .testMaxLength(10)
                            .testEqualsNoCase("hELLOwORLD")
                            .validate();
