usingComparator
public DoubleAssert usingComparator(java.util.Comparator<? super java.lang.Double> customComparator)
Description copied from class:AbstractAssert
Use given custom comparator instead of relying on actual type A equals method for incoming assertion checks.Custom comparator is bound to assertion instance, meaning that if a new assertion is created, it will use default comparison strategy.
Examples :
// frodo and sam are instances of Character with Hobbit race (obviously :). // raceComparator implements Comparator<Character> assertThat(frodo).usingComparator(raceComparator).isEqualTo(sam);
- Specified by:
usingComparator
in interfaceAssert<DoubleAssert,java.lang.Double>
- Overrides:
usingComparator
in classAbstractComparableAssert<DoubleAssert,java.lang.Double>
- Parameters:
customComparator
- the comparator to use for incoming assertion checks.- Returns:
this
assertion object.
-
usingDefaultComparator
public DoubleAssert usingDefaultComparator()
Description copied from class:AbstractAssert
Revert to standard comparison for incoming assertion checks.This method should be used to disable a custom comparison strategy set by calling
Assert.usingComparator(Comparator)
.- Specified by:
usingDefaultComparator
in interfaceAssert<DoubleAssert,java.lang.Double>
- Overrides:
usingDefaultComparator
in classAbstractComparableAssert<DoubleAssert,java.lang.Double>
- Returns:
this
assertion object.
