Constructor Details

ClassValue

public ClassValue(Class<T> value)

Creates a new ClassValue.

Parameters:

value - the value; must not be null

Throws:

NullPointerException - if value is null

Method Details

compareTo

public final int compareTo(ClassValue<T> other)

Specified by:

compareTo in interface Comparable<T>

describeConstable

public final Optional<DynamicConstantDesc<ClassValue<T>>> describeConstable()

Specified by:

describeConstable in interface Constable

equals

public final boolean equals(Object other)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

other - the object with which to compare

Returns:

true if this object is the same as the other argument; false otherwise.

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

of

public static final <T> ClassValue<T> of(Class<T> c)

Returns a ClassValue suitable for the supplied arguments.

Type Parameters:

T - the type of the class

Parameters:

c - a Class; must not be null

Returns:

a non-null ClassValue

Throws:

NullPointerException - if c is null

value

public Class<T> value()

Returns the value of the value record component.

Returns:

the value of the value record component
