iText io.jar Source Code
io.jar is a component in iText Java library to provide input/output functionalities. iText Java library allows you to generate and manage PDF documents.
The Source Code files are provided together with the JAR file in the binary packge like iText7-Core-7.1.4.zip. You can download it at iText 7 Core Download site.
You can compile it to generate your JAR file, using io.pom as the build configuration file.
The source code of io-7.1.4.jar is provided below:
