Member Data Documentation

ARRAY

final Equality<Object> javolution.util.function.Equalities.ARRAY = new ArrayComparatorImpl()

static

A content array comparator. If the content of an array is also an array (multi-dimensional arrays), that same comparator is used for equality and comparison (recursive). The standard comparator is used for non-array elements.

Definition at line 50 of file Equalities.java.

IDENTITY

final Equality<Object> javolution.util.function.Equalities.IDENTITY = new IdentityComparatorImpl<Object>()

static

A comparator for which instances are only equals to themselves. For comparisons an empirical method consistent with equals (

==  

) is used.

LEXICAL

final Equality<CharSequence> javolution.util.function.Equalities.LEXICAL = new LexicalComparatorImpl()

static

A lexicographic comparator for any CharSequence.

Definition at line 57 of file Equalities.java.

Referenced by javolution.text.CharArray.compareTo(), and javolution.text.Text.compareTo().

LEXICAL_CASE_INSENSITIVE

final Equality<CharSequence> javolution.util.function.Equalities.LEXICAL_CASE_INSENSITIVE = new LexicalCaseInsensitiveComparatorImpl()

static

A case insensitive lexicographic comparator for any CharSequence.

Definition at line 64 of file Equalities.java.

LEXICAL_FAST

final Equality<CharSequence> javolution.util.function.Equalities.LEXICAL_FAST = new LexicalFastComparatorImpl()

static

An optimized lexical comparator for any CharSequence taking a sample of few characters instead of the whole character sequence to calculate the hash code (still equality comparison checks all characters).

Definition at line 73 of file Equalities.java.

STANDARD

final Equality<Object> javolution.util.function.Equalities.STANDARD = new StandardComparatorImpl<Object>()

static

A standard object comparator (based on the object hashCode and equals methods). Comparisons either use the object natural order (which should be consistent with equals) or an empirical method (if the object does not implement Comparable).
