<p>add Signature Changer page</p> <p><b>New page</b></p><div>Signature Changer is a tool to patch generic type signatures for classes, fields, and methods in Java class files. It takes in a [[Sparrow]] data file and applies those patches to a jar file. This tool was originally created by [https://github.com/Gaming32 Gaming32].<br /> <br /> == Generic Type Signatures ==<br /> <br /> Classes, fields, methods, and variables all define their generic type signatures in Java class files.<br /> <br /> Obfuscators such as [https://www.guardsquare.com/proguard ProGuard] may remove them to shrink the jar file size. This is generally not a problem, since it does not affect the runtime behavior of a Java application. However, they do make a difference at &#039;&#039;compile time&#039;&#039;.<br /> <br /> Generics are a useful tool for writing type-safe code. However, if the generic type signatures are missing, code can become bothersome to write and more prone to errors.<br /> <br /> == Signature Changer ==<br /> <br /> Exceptor patches the generic type signatures in a jar using a [[Sparrow]] data file. It has the following features:<br /> <br /> * Removing, adding or modifying generic type signatures for classes, fields, and methods.<br /> * Generating a [[Sparrow]] file from a given jar file.</div>
