Answer back the tag of this verification type info as described in the JVM specifications.

    

  • 0 for the top type
    • 

  • 1 for the int type
    • 

  • 2 for the float type
    • 

  • 3 for the double type
    • 

  • 4 for the long type
    • 

  • 5 for the null type
    • 

  • 6 for the uninitialized this type
    • 

  • 7 for the object type
    • 

  • 8 for the uninitialized offset type
    •
