Method Detail

getLowerBounds

public Type[] getLowerBounds()
                      throws TypeNotPresentException,
                             MalformedParameterizedTypeException

Description copied from interface: WildcardType

Returns the array of types that represent the lower bounds of this type. The default lower bound is null, in which case an empty array is returned. Since only one lower bound is allowed, the returned array's length will never exceed one.

Specified by:

getLowerBounds in interface WildcardType

Returns:

an array containing the lower bounds types

Throws:

TypeNotPresentException - if any of the bounds points to a missing type

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

getUpperBounds

public Type[] getUpperBounds()
                      throws TypeNotPresentException,
                             MalformedParameterizedTypeException

Description copied from interface: WildcardType

Returns the array of types that represent the upper bounds of this type. The default upper bound is Object.

Specified by:

getUpperBounds in interface WildcardType

Returns:

an array containing the upper bounds types

Throws:

TypeNotPresentException - if any of the bounds points to a missing type

MalformedParameterizedTypeException - if any bound points to a type that cannot be instantiated for some reason

equals

public boolean equals(Object o)

Description copied from class: Object

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Overrides:

equals in class Object

Parameters:

o - the object to compare this instance with.

Returns:

true if the specified object is equal to this Object; false otherwise.

See Also:

Object.hashCode()

hashCode

public int hashCode()

Description copied from class: Object

Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Overrides:

hashCode in class Object

Returns:

this object's hash code.

See Also:

Object.equals(java.lang.Object)

toString

public String toString()

Description copied from class: Object

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

   getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Overrides:

toString in class Object

Returns:

a printable representation of this object.
