Class SignatureUtils

java.lang.Object

io.micronaut.sourcegen.bytecode.core.SignatureUtils

@Internal
public final class SignatureUtils
extends Object

JVM generic-signature operations shared by bytecode writers.

The result is the standard JVMS signature string. Keeping this operation independent of a bytecode library lets the ASM and JDK ClassFile backends use exactly the same generic metadata.
