Method Detail

equalsAny

public static boolean equalsAny(Object source,
                                Object... targets)

Whether a source object equals ANY of the target objects.

Parameters:

source - object being tested for equality with targets

targets - one or more objects to be tested with source for equality

Returns:

true if any of the target objects are equal

equalsAnyIgnoreCase

public static boolean equalsAnyIgnoreCase(CharSequence source,
                                          CharSequence... targets)

Whether a source string equals ANY of the target string.

Parameters:

source - string being tested for equality with target strings

targets - one or more strings to be tested with source string for equality

Returns:

true if any of the target strings are equal

equalsAll

public static boolean equalsAll(Object source,
                                Object... targets)

Whether a source object equals ALL of the target objects

Parameters:

source - object being tested for equality with targets

targets - one or more objects to be tested with source for equality

Returns:

true if all of the target objects are equal

equalsAllIgnoreCase

public static boolean equalsAllIgnoreCase(CharSequence source,
                                          CharSequence... targets)

Whether a source string equals ALL of the target string.

Parameters:

source - string being tested for equality with target strings

targets - one or more strings to be tested with source string for equality

Returns:

true if all of the target strings are equal

equalsNone

public static boolean equalsNone(Object source,
                                 Object... targets)

Whether a source object equals NONE of the target objects

Parameters:

source - object being tested for equality with targets

targets - one or more objects to be tested with source for equality

Returns:

true if none of the target objects are equal

equalsNoneIgnoreCase

public static boolean equalsNoneIgnoreCase(String source,
                                           String... targets)

Whether a source string equals NONE of the target string.

Parameters:

source - string being tested for equality with target strings

targets - one or more strings to be tested with source string for equality

Returns:

true if none of the target strings are equal

equalsMap

public static boolean equalsMap(Map<?,?> map1,
                                Map<?,?> map2)

Compares that two maps are equals, regardless of entry orders. It does so by making sure the two maps are the same size and the first map contains all entries of the other one. Map elements should implement equals.

Parameters:

map1 - first map

map2 - second map

Returns:

true if the two maps are equal
