Examples of org.objectweb.asm.MethodVisitor.visitLdcInsn()

org.objectweb.asm.MethodVisitor.visitLdcInsn()
Visits a LDC instruction. @param cst the constant to be loaded on the stack. This parameter must bea non null {@link Integer}, a {@link Float}, a {@link Long}, a {@link Double} a {@link String} (or a {@link Type} for.class constants, for classes whose version is 49.0 or more).
