Method Detail

make

public static WildcardTypeImpl make(FieldTypeSignature[] ubs,
                                    FieldTypeSignature[] lbs,
                                    GenericsFactory f)

Factory method.

Parameters:

ubs - - an array of ASTs representing the upper bounds for the type variable to be created

lbs - - an array of ASTs representing the lower bounds for the type variable to be created

f - - a factory that can be used to manufacture reflective objects that represent the bounds of this wildcard type

Returns:

a wild card type with the requested bounds and factory

getUpperBounds

public Type[] getUpperBounds()

Returns an array of Type objects representing the upper bound(s) of this type variable. Note that if no upper bound is explicitly declared, the upper bound is Object.

For each upper bound B :

• if B is a parameterized type or a type variable, it is created, (see #ParameterizedType for the details of the creation process for parameterized types).
• Otherwise, B is resolved.

Specified by:

getUpperBounds in interface WildcardType

Returns:

an array of Types representing the upper bound(s) of this type variable

Throws:

TypeNotPresentException - if any of the bounds refers to a non-existent type declaration

MalformedParameterizedTypeException - if any of the bounds refer to a parameterized type that cannot be instantiated for any reason

getLowerBounds

public Type[] getLowerBounds()

Returns an array of Type objects representing the lower bound(s) of this type variable. Note that if no lower bound is explicitly declared, the lower bound is the type of null. In this case, a zero length array is returned.

For each lower bound B :

• if B is a parameterized type or a type variable, it is created, (see #ParameterizedType for the details of the creation process for parameterized types).
• Otherwise, B is resolved.

Specified by:

getLowerBounds in interface WildcardType

Returns:

an array of Types representing the lower bound(s) of this type variable

Throws:

TypeNotPresentException - if any of the bounds refers to a non-existent type declaration

MalformedParameterizedTypeException - if any of the bounds refer to a parameterized type that cannot be instantiated for any reason

toString

public String toString()

Description copied from class: Object

toString creates a printable string that represents this object for debugging purposes.

The default implementation returns getClass().getName() + '@' + Integer.toHexString(hashCode()).

Overrides:

toString in class Object

Returns:

a string identifying this object.

equals

public boolean equals(Object o)

Description copied from class: Object

equals compares this object to another object.

Equals must be symmetric (a.equals(b) == b.equals(a)), reflexive (a.equals(a)==true) and transitive (a.equals(b) && b.equals(c) IMPLIES (a.equals(c))) and not change over time (a.equals(b) == a.equals(b)). a.equals(null) should always return false.

If a.equals(b) is true for two objects a and b, then a.hashCode()==b.hashCode() must hold.

The default implementation of equals returns this==other.

Overrides:

equals in class Object

Parameters:

o - the other object.

Returns:

if this and other are considered equal.

hashCode

public int hashCode()

Description copied from class: Object

hashCode returns a hash code for this object. The hash code must be equal for two objects a and b if a.equals(b) is true.

The default implementation returns System.identityHashCode(this).

Overrides:

hashCode in class Object

Returns:

a hash code value.
