extends Object

Constructor Summary

BsonUtils()

Method Summary

static ObjectId	readObjectId(byte[] bytes) The BSON specification (or rather the MongoDB documentation) defines the structure of this data: "A BSON ObjectID is a 12-byte value consisting of a 4-byte timestamp (seconds since epoch), a 3-byte machine id, a 2-byte process id, and a 3-byte counter.
static ObjectId	readObjectId(String bytesInHex) Read the ObjectId from the hexadecimal string representation of the ObjectId.
static String	regexFlagsFor(int flags)
static String	regexFlagsFor(Pattern pattern)
static int	regexFlagsFrom(String flags)
static boolean	valuesAreEqual(Object thisValue, Object thatValue)
static void	writeObjectId(ObjectId id, byte[] b) Write the 12-byte representation of the ObjectId per the BSON specification (or rather the MongoDB documentation).

regexFlagsFrom

public static int regexFlagsFrom(String flags)

regexFlagsFor

public static String regexFlagsFor(Pattern pattern)

regexFlagsFor

public static String regexFlagsFor(int flags)

readObjectId

public static ObjectId readObjectId(byte[] bytes)

The BSON specification (or rather the MongoDB documentation) defines the structure of this data:

"A BSON ObjectID is a 12-byte value consisting of a 4-byte timestamp (seconds since epoch), a 3-byte machine id, a 2-byte process id, and a 3-byte counter. Note that the timestamp and counter fields must be stored big endian unlike the rest of BSON. This is because they are compared byte-by-byte and we want to ensure a mostly increasing order."

Parameters:

bytes -

Returns:

the ObjectId

readObjectId

public static ObjectId readObjectId(String bytesInHex)

Read the ObjectId from the hexadecimal string representation of the ObjectId.

Parameters:

bytesInHex - the hexadecimal identifier

Returns:

the ObjectId

writeObjectId

public static void writeObjectId(ObjectId id,
                                 byte[] b)

Write the 12-byte representation of the ObjectId per the BSON specification (or rather the MongoDB documentation).

Parameters:

id - the ObjectId; may not be null

b - the bytes into which the object ID should be written

valuesAreEqual

public static boolean valuesAreEqual(Object thisValue,
                                     Object thatValue)
