ComparisonStrategy

Direct Known Subclasses:

public class StandardComparisonStrategy
extends AbstractComparisonStrategy

Implements ComparisonStrategy contract with a comparison strategy based on Objects.areEqual(Object, Object) method, it is also based on Comparable.compareTo(Object) when Object are Comparable method.

Constructor Summary

protected

StandardComparisonStrategy() Creates a new StandardComparisonStrategy, comparison strategy being based on Objects.areEqual(Object, Object).

Method Summary

boolean	areEqual(Object actual, Object other) Returns true if actual and other are equal based on Objects.areEqual(Object, Object), false otherwise.
String	asText()
Iterable<?>	duplicatesFrom(Iterable<?> iterable) Returns any duplicate elements from the given collection according to Objects.areEqual(Object, Object) comparison strategy.
static StandardComparisonStrategy	instance() Returns the singleton instance of this class.
boolean	isGreaterThan(Object actual, Object other) Returns true if actual is greater than other, false otherwise.
boolean	isLessThan(Object actual, Object other) Returns true if actual is less than other, false otherwise.
boolean	isStandard() Return true if comparison strategy is default/standard, false otherwise

void	iterableRemoves(Iterable<?> iterable, Object value) Look for given value in given Iterable according to the implemented comparison strategy, if value is found it is removed from it. If given Iterable is null, does nothing.
protected Set<Object>	newSetUsingComparisonStrategy() Returns a Set honoring the comparison strategy used.
boolean	stringContains(String string, String sequence) Returns true if given string contains given sequence according to the implemented comparison strategy, false otherwise.
boolean	stringEndsWith(String string, String suffix) Returns true if sstring ends with suffix according to the implemented comparison strategy, false otherwise.
boolean	stringStartsWith(String string, String prefix) Returns true if string starts with prefix according to the implemented comparison strategy, false otherwise.

Constructor Detail

StandardComparisonStrategy

protected StandardComparisonStrategy()

Creates a new StandardComparisonStrategy, comparison strategy being based on Objects.areEqual(Object, Object).

Method Detail

instance

public static StandardComparisonStrategy instance()

Returns the singleton instance of this class.

Returns:

the singleton instance of this class.

newSetUsingComparisonStrategy

protected Set<Object> newSetUsingComparisonStrategy()

Description copied from class: AbstractComparisonStrategy

Returns a Set honoring the comparison strategy used.

Specified by:

newSetUsingComparisonStrategy in class AbstractComparisonStrategy

Returns:

a Set honoring the comparison strategy used.

asText

public String asText()

Specified by:

asText in class AbstractComparisonStrategy

areEqual

public boolean areEqual(Object actual,
                        Object other)

Returns true if actual and other are equal based on Objects.areEqual(Object, Object), false otherwise.

Parameters:

actual - the object to compare to other

other - the object to compare to actual

Returns:

true if actual and other are equal based on Objects.areEqual(Object, Object), false otherwise.

iterableContains

public boolean iterableContains(Iterable<?> iterable,
                                Object value)

Returns true if given Iterable contains given value based on Objects.areEqual(Object, Object), false otherwise.
If given Iterable is null, return false.

Parameters:

iterable - the Iterable to search value in

value - the object to look for in given Iterable

Returns:

true if given Iterable contains given value based on Objects.areEqual(Object, Object), false otherwise.

iterableRemoves

public void iterableRemoves(Iterable<?> iterable,
                            Object value)

Look for given value in given Iterable according to the implemented comparison strategy, if value is found it is removed from it.
If given Iterable is null, does nothing.

Parameters:

iterable - the Iterable we want remove value from

value - object to remove from given Iterable

duplicatesFrom

public Iterable<?> duplicatesFrom(Iterable<?> iterable)

Returns any duplicate elements from the given collection according to Objects.areEqual(Object, Object) comparison strategy.

Specified by:

duplicatesFrom in interface ComparisonStrategy

Overrides:

duplicatesFrom in class AbstractComparisonStrategy

Parameters:

iterable - the given Iterable we want to extract duplicate elements.

Returns:

an Iterable containing the duplicate elements of the given one. If no duplicates are found, an empty Iterable is returned.

stringStartsWith

public boolean stringStartsWith(String string,
                                String prefix)

Description copied from interface: ComparisonStrategy

Returns true if string starts with prefix according to the implemented comparison strategy, false otherwise.

Parameters:

string - the String we want to look starting prefix

prefix - the prefix String to look for at string's start

Returns:

true if string starts with prefix according to the implemented comparison strategy, false otherwise.

stringEndsWith

public boolean stringEndsWith(String string,
                              String suffix)

Description copied from interface: ComparisonStrategy

Returns true if sstring ends with suffix according to the implemented comparison strategy, false otherwise.

Parameters:

string - the String we want to look starting suffix

suffix - the suffix String to look for at string's end

Returns:

true if string ends with suffix according to the implemented comparison strategy, false otherwise.

stringContains

public boolean stringContains(String string,
                              String sequence)

Description copied from interface: ComparisonStrategy

Returns true if given string contains given sequence according to the implemented comparison strategy, false otherwise.

Parameters:

string - the string to search sequence in (must not be null)

sequence - the String to look for in given string

Returns:

true if given string contains given sequence according to the implemented comparison strategy, false otherwise.

isGreaterThan
