API Reference

Public Methods

Method	Description
isEnumeration	Checks if the given object is an instance of Enumeration.
isEnumeration	Checks if the given class type is assignable from Enumeration.
of	Creates an Enumeration from the provided elements.
ofEnumeration	Creates an Enumeration from the provided elements array.

Method Details

isEnumeration

public static boolean isEnumeration(@Nullable Object values)

Checks if the given object is an instance of Enumeration.

Example Usage

`boolean result = EnumerationUtils.isEnumeration(someObject);
if (result) {
    Enumeration enumeration = (Enumeration) someObject;
    while (enumeration.hasMoreElements()) {
        System.out.println(enumeration.nextElement());
    `
}
}

isEnumeration

public static boolean isEnumeration(@Nullable Class<?> type)

Checks if the given class type is assignable from Enumeration.

Example Usage

`boolean result = EnumerationUtils.isEnumeration(SomeEnumClass.class);
if (result) {
    // The class is an Enumeration
`
}

of

public static <E> Enumeration<E> of(E... elements)

Creates an Enumeration from the provided elements.

Internally, this method delegates to #ofEnumeration(Object[]) to create a new enumeration based on the given array of elements.

Example Usage

`Enumeration en = EnumerationUtils.of("one", "two", "three");
while (en.hasMoreElements()) {
    System.out.println(en.nextElement());
`
}

ofEnumeration

public static <E> Enumeration<E> ofEnumeration(E... elements)

Creates an Enumeration from the provided elements array.

This method constructs a new ArrayEnumeration instance backed by the given array, allowing sequential read-only access to the array elements.

Example Usage

`Enumeration en = EnumerationUtils.ofEnumeration("apple", "banana", "cherry");
while (en.hasMoreElements()) {
    System.out.println(en.nextElement());
`
}
