public int size()
```
  Number of 32 bit words occupied by this type if primitive, or 0 if non-primitive.
- signature
```
public java.lang.String signature()

  equals in class java.lang.Object
- hasPrimitiveNarrowingConversionFrom
```
public boolean hasPrimitiveNarrowingConversionFrom(Type t)
```
  Return true iff there is a primitive narrowing conversion from Type t to this type.
- hasPrimitiveWideningConversionFrom
```
public boolean hasPrimitiveWideningConversionFrom(Type t)
```
  Return true iff there is a primitive widening conversion from Type t to this type.
- returnTypeCollision
```
private boolean returnTypeCollision(java.util.Set<MethodInfo> set1,
                                    java.util.Set<MethodInfo> set2)
```

```
private boolean isInterface()
```
- modifiers
```
private int modifiers()

```
public boolean hasReferenceNarrowingConversionFrom(Type t)
```
  Return true iff there is a reference narrowing conversion from Type t to this type.
- hasReferenceWideningConversionFrom
```
public boolean hasReferenceWideningConversionFrom(Type t)
```
  Return true iff there is a reference widening conversion from Type t to this type.
- isAssignmentConvertibleFrom
```
public boolean isAssignmentConvertibleFrom(Type t)
```
  Return true iff there is an assignment conversion from Type t to this type.
- isCastingConvertibleFrom
```
public boolean isCastingConvertibleFrom(Type t)
```
  Return true iff there is a casting conversion from Type t to this type.
- unaryPromotion
```
public Type unaryPromotion()
```
  Return the type that is a unary promotion of this type.
- binaryPromotion
```
public Type binaryPromotion(Type t)
```
  Return the type that is the binary promotion of this type and Type t.
- isMethodInvocationConvertibleFrom
```
public boolean isMethodInvocationConvertibleFrom(Type t)
```
  Return true iff one of the following statements is true:
  1. this.equals( t ) .
  2. There is a widening primitive conversion from Type t to this Type (see JLS 5.1.2).
  3. There is a widening reference conversion from Type t to this Type (see JLS 5.1.4).
  This is similar to Class.isAssignmentCompatibleFrom, but also handles widening primitive conversions. Throws NullPointerException if t == null.
