  - isAnyType
```
boolean isAnyType()
```
    Returns:
    
    whether this is the any type, The any type is the subtype of every reference type and its only instance is null.
  - isPrimitive
```
boolean isPrimitive()
```
    Returns:
    
    whether this is a primitive type (i.e. one of boolean, char, byte, short, int, long, float, double).
  - getWrapperIfPrimitive
```
TypeReference getWrapperIfPrimitive()
```
    Returns:
    
    the corresponding wrapper TypeReference if this type references is a primitive type. Returns this otherwise.
  - isWrapper
```
boolean isWrapper()
```
    Checks whether this type is one of the wrapper types for the primitive value types.
    
    Returns:
    
    wither this is one of the wrapper types for the primitive value types.
  - getPrimitiveIfWrapper
```
TypeReference getPrimitiveIfWrapper()
```
    Returns:
    
    the corresponding primitive TypeReference if this type references is a wrapper type. Returns this otherwise.
  - isVoid
```
boolean isVoid()
```
    Returns:
    
    whether this type is 'void' (doesn't include 'java.lang.Void')
  - isAssignableFrom
```
boolean isAssignableFrom(TypeReference typeReference)
```
    Determines if the specified TypeReference parameter can be assigned to this TypeReference. It returns true if so; otherwise it returns false.
    
    Parameters:
    
    typeReference -
    
    Returns:
    
    returns true is the specified type reference parameter can be assigned to this type reference.
  - isInferred
```
boolean isInferred()
```
    Whether the given type reference is an inferred reference. That is the type is to be computed from some Expression, e.g. a method body or a field initializer. Inferred type references can only be used as handles, and will through an UnsupportedOperationException on every method other than
    Returns:
    
    whether this type reference is an inferred type reference.
  - getDeclaredSuperTypes
```
java.lang.Iterable<? extends TypeReference> getDeclaredSuperTypes()
```
    Returns:
    
    the supertypes (superclass and interfaces) directly implemented/extended by this type
    
    Since:
    
    2.7
  - getDeclaredResolvedMethods
```
java.lang.Iterable<? extends ResolvedMethod> getDeclaredResolvedMethods()
```
    Returns:
    
    the resolved methods directly declared by this type
    
    Since:
    
    2.7
  - getDeclaredResolvedConstructors
```
java.lang.Iterable<? extends ResolvedConstructor> getDeclaredResolvedConstructors()
```
    Returns:
    
    the resolved constructors directly declared by this type
    
    Since:
    
    2.7
  - getAllResolvedMethods
```
java.lang.Iterable<? extends ResolvedMethod> getAllResolvedMethods()
```
    Computes all the resolved methods that can be called on this type, either because they were declared directly by the type or by one of its supertypes. For overloaded methods, the one declared closest to this type is used. E.g. when called on the class C in this hierarchy:
```
 class A {
  def CharSequence foo()
 }
 class B extends A {
  override String foo()
 }
 class C extends B {}
  
 B#foo() would be contained, but not A#foo().
```
    Returns:
    
    the resolved methods declared in this type and its supertypes.
    
    Since:
    
    2.7
  - equals
```
boolean equals(java.lang.Object obj)
```
    Checks whether this type reference equals the given type reference. For type References where isInferred() is true, the implementation is based on identity of the underlying AST.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    obj -
    
    Returns:
    
    whether the given obj is the same instance
    
    Since:
    
    2.7
  - hashCode
```
int hashCode()
```
    Value-based for all TypeReferences where isInferred() is false.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Since:
    
    2.7
  - toString
```
java.lang.String toString()
```
    A string representation for this type reference. If this reference is resolved, it will return the simple name of this reference. Otherwise a technical information about the inferred type reference.
    
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    
    a string representation
    
    Since:
