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 aSet
honoring the comparison strategy used.- Specified by:
newSetUsingComparisonStrategy
in classAbstractComparisonStrategy
- Returns:
- a
Set
honoring the comparison strategy used.
-
asText
public String asText()
- Specified by:
asText
in classAbstractComparisonStrategy
-
areEqual
public boolean areEqual(Object actual, Object other)
Returns true if actual and other are equal based onObjects.areEqual(Object, Object)
, false otherwise.- Parameters:
actual
- the object to compare to otherother
- 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 givenIterable
contains given value based onObjects.areEqual(Object, Object)
, false otherwise.
If givenIterable
is null, return false.- Parameters:
iterable
- theIterable
to search value invalue
- the object to look for in givenIterable
- Returns:
- true if given
Iterable
contains given value based onObjects.areEqual(Object, Object)
, false otherwise.
-
iterablesRemoveFirst
public void iterablesRemoveFirst(Iterable<?> iterable, Object value)
Removes the first value initerable
that matches thevalue
according to the implemented comparison strategy. If givenIterable
is null, does nothing.
-
duplicatesFrom
public Iterable<?> duplicatesFrom(Iterable<?> iterable)
Returns any duplicate elements from the given collection according toObjects.areEqual(Object, Object)
comparison strategy.- Specified by:
duplicatesFrom
in interfaceComparisonStrategy
- Overrides:
duplicatesFrom
in classAbstractComparisonStrategy
- Parameters:
iterable
- the givenIterable
we want to extract duplicate elements.- Returns:
- an
Iterable
containing the duplicate elements of the given one. If no duplicates are found, an emptyIterable
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

- 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 string ends with suffix according to the implemented comparison strategy, false otherwise.- Parameters:
string
- the String we want to look starting suffixsuffix

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

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
