Method Detail

isSubrange

public final boolean isSubrange(Range other)

Returns:

true if this Interval is a "subrange" of the other interval

toBytes

public abstract byte[] toBytes()

Returns:

a byte [] representation of this range. The representation will be 8 bytes if isLong() is false, 10 bytes otherwise.

toBytes

public abstract void toBytes(byte[] dest,
                             int offset)

Places a byte[] representation of this range in the specified array at the specified offset.

getLow

public abstract long getLow()

getHigh

public abstract long getHigh()

createRange

public static Range createRange(long start,
                                long end)

Returns:

a Range with the provided values that will use the least amount of memory.

createRange

public static Range createRange(long singleton)

Returns:

a range (singleton,singleton)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

isLong

public abstract boolean isLong()

Returns:

true if this range has values > Integer.MAX_VALUE.

getLength

public long getLength()

Returns the length of this range.
