Constructor Detail

Marker

public Marker(Type type,
              Optional<Block> valueBlock,
              Marker.Bound bound)

LOWER UNBOUNDED is specified with an empty value and a ABOVE bound UPPER UNBOUNDED is specified with an empty value and a BELOW bound

Method Detail

upperUnbounded

public static Marker upperUnbounded(Type type)

lowerUnbounded

public static Marker lowerUnbounded(Type type)

above

public static Marker above(Type type,
                           Object value)

exactly

public static Marker exactly(Type type,
                             Object value)

below

public static Marker below(Type type,
                           Object value)

getType

public Type getType()

getValueBlock

public Optional<Block> getValueBlock()

getValue

public Object getValue()

getPrintableValue

public Object getPrintableValue(SqlFunctionProperties properties)

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(SqlFunctionProperties properties)

canonicalize

public Marker canonicalize(boolean removeConstants)
