Method Detail

getActualTypeArguments

public Type[] getActualTypeArguments()

Description copied from interface: ParameterizedType

Returns an array of the actual type arguments for this type.

If this type models a non parameterized type nested within a parameterized type, this method returns a zero length array. The generic type of the following field declaration is an example for a parameterized type without type arguments.

 A<String>.B field;

 class A<T> {
     class B {
     }
 }

Specified by:

getActualTypeArguments in interface ParameterizedType

Returns:

the actual type arguments

getOwnerType

public Type getOwnerType()

Description copied from interface: ParameterizedType

Returns the parent / owner type, if this type is an inner type, otherwise null is returned if this is a top-level type.

Specified by:

getOwnerType in interface ParameterizedType

Returns:

the owner type or null if this is a top-level type

getRawType

public Class getRawType()

Description copied from interface: ParameterizedType

Returns the declaring type of this parameterized type.

The raw type of Set<String> field; is Set.

Specified by:

getRawType in interface ParameterizedType

Returns:

the raw type of this parameterized type

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.
