isBsonDocument

public static Boolean isBsonDocument(Object value)

Checks if the given object represents a BSON document.

Parameters:

value - the object to check; should be non-null to determine if it is a BSON document

Returns:

true if the object is a BSON document, false otherwise

isObjectId

public static boolean isObjectId(Object obj)

Determines whether the given object is a BSON ObjectId.

Parameters:

obj - the object to check; should be non-null to determine if it is a BSON ObjectId

Returns:

true if the object is a BSON ObjectId, false otherwise

isBsonTimestamp

public static boolean isBsonTimestamp(Object obj)

Determines whether the given object is a BSON BsonTimestamp.

Parameters:

obj - the object to check; should be non-null to determine if it is a BSON BsonTimestamp

Returns:

true if the object is a BSON BsonTimestamp, false otherwise

getBsonTimestampValue

public static long getBsonTimestampValue(Object bsonTimestamp)

Retrieves the value of a BSON BsonTimestamp as a long value.

Parameters:

bsonTimestamp - the BSON BsonTimestamp object; should be non-null

Returns:

the value of the BSON BsonTimestamp

Throws:

IllegalArgumentException - if the argument is not a BSON BsonTimestamp

getType

public static String getType(Object bsonType)

getTypeFromNumber

public static Object getTypeFromNumber(Integer number)

Retrieves the BSON type corresponding to the given integer value.

Parameters:

number - the integer value representing the BSON type

Returns:

the BSON type object, or null if not found

getTypeFromAlias

public static Object getTypeFromAlias(String alias)

Retrieves the BSON type corresponding to the given alias string.

Parameters:

alias - the alias string representing the BSON type

Returns:

the BSON type object, or null if not found

isBsonRegularExpression

public static boolean isBsonRegularExpression(Object object)

Checks if the given object is a BSON regular expression.

Parameters:

object - the object to check; should be non-null to determine if it is a BSON regular expression

Returns:

true if the object is a BSON regular expression, false otherwise

bsonRegexGetPattern

public static String bsonRegexGetPattern(Object value)

Retrieves the pattern from a BSON regular expression object.

Parameters:

value - the object representing a BSON regular expression. Must not be null and must be a valid BSON regular expression.

Returns:

a String representing the pattern of the BSON regular expression.

Throws:

NullPointerException - if the provided value is null.

IllegalArgumentException - if the provided value is not a BSON regular expression.

RuntimeException - if an error occurs while invoking the method to retrieve the pattern.

bsonRegexGetOptions

public static String bsonRegexGetOptions(Object value)

Retrieves the options associated with a BSON regular expression.

Parameters:

value - the object representing a BSON regular expression. Must not be null and must be a valid BSON regular expression.

Returns:

a String representing the options associated with the BSON regular expression.

Throws:
