jumpPositive

void jumpPositive(KernelParam from,
                cn.wensiqun.asmsupport.org.objectweb.asm.Label posLbl,
                cn.wensiqun.asmsupport.org.objectweb.asm.Label negLbl)

To execute positive jump and generate relevant byte code.

For example : the operator '1 == 1' then the positive jump is if_icmpeq. the operator 'if(isTrue()){ ... }'(here we suppose the method isTrue) return boolean value, then the positive jump is ifne

jumpNegative

void jumpNegative(KernelParam from,
                cn.wensiqun.asmsupport.org.objectweb.asm.Label posLbl,
                cn.wensiqun.asmsupport.org.objectweb.asm.Label negLbl)

To execute negative jump and generate relevant byte code.

For example : the operator '1 == 1' then the negative jump is if_icmpne. the operator 'if(isTrue()){ ... }'(here we suppose the method isTrue) return boolean value, then the positive jump is ifeq
