  Returns:
- descriptor
```
public static String descriptor(JvmType t,
                                boolean generic)
```
  This method returns a JVM descriptor string for the type in question. The format of the string is defined in "The Java Virtual Machine Specification, 2nd ed", Section 4.3. Example descriptor strings include:
  
  Type Descriptor
  
  int I
  
  boolean Z
  
  float[] F[
  
  java.lang.Integer Ljava/lang/Integer;
  
  int(Double,Float) (DF)I
  
  The descriptor string is used, amongst other things, to uniquely identify a class in the ClassTable.
  See the JVM Specification for more information.
  
  Parameters:
  
  t - The type to generate the descriptor for
  
  generic - True indicates generic information should be included.
  
  Returns:
- slotSize
```
public static int slotSize(JvmType type)
```
  Determine the slot size for the corresponding Java type.
  
  Parameters:
  
  type - The type to determine the slot size for.
  
  Returns:
  
  the slot size in slots.

int	I
boolean	Z
float[]	F[
