Method Details

compareTo

public int compareTo(byte[] value,
 int offset,
 int length)

Description copied from class: ByteArrayComparable

Special compareTo method for subclasses, to avoid copying byte[] unnecessarily.

Specified by:

compareTo in class ByteArrayComparable

Parameters:

value - byte[] to compare

offset - offset into value

length - number of bytes to compare

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

compareTo

public int compareTo(ByteBuffer value,
 int offset,
 int length)

Description copied from class: ByteArrayComparable

Special compareTo method for subclasses, to avoid copying bytes unnecessarily.

Overrides:

compareTo in class ByteArrayComparable

Parameters:

value - bytes to compare within a ByteBuffer

offset - offset into value

length - number of bytes to compare

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

toByteArray

public byte[] toByteArray()

Returns The comparator serialized using pb

Specified by:

toByteArray in class ByteArrayComparable

parseFrom

public static LongComparator parseFrom(byte[] pbBytes)
                                throws DeserializationException

Parses a serialized representation of LongComparator

Parameters:

pbBytes - A pb serialized LongComparator instance

Returns:

An instance of LongComparator made from bytes

Throws:

DeserializationException - if an error occurred

• toByteArray()

areSerializedFieldsEqual

boolean areSerializedFieldsEqual(LongComparator other)

Returns true if and only if the fields of the comparator that are serialized are equal to the corresponding fields in other. Used for testing.
