Constructor Detail

Marker

public Marker(SerializableNativeValue value,
              Marker.Bound bound)

Method Detail

upperUnbounded

public static Marker upperUnbounded(Class<?> type)

lowerUnbounded

public static Marker lowerUnbounded(Class<?> type)

above

public static Marker above(Comparable<?> value)

exactly

public static Marker exactly(Comparable<?> value)

below

public static Marker below(Comparable<?> value)

getType

public Class<?> getType()

getValue

public Comparable<?> getValue()

getSerializableNativeValue

public SerializableNativeValue getSerializableNativeValue()

getBound

public Marker.Bound getBound()

isUpperUnbounded

public boolean isUpperUnbounded()

isLowerUnbounded

public boolean isLowerUnbounded()

isAdjacent

public boolean isAdjacent(Marker other)

Adjacency is defined by two Markers being infinitesimally close to each other. This means they must share the same value and have adjacent Bounds.

greaterAdjacent

public Marker greaterAdjacent()

lesserAdjacent

public Marker lesserAdjacent()

compareTo

public int compareTo(Marker o)

Specified by:

compareTo in interface Comparable<Marker>

min

public static Marker min(Marker marker1,
                         Marker marker2)

max

public static Marker max(Marker marker1,
                         Marker marker2)

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
