Methods

	Name	Description
	BuildString	Builds a string version of an identifier.
	ConvertToArray	Converts a formatted string identifier into its equivalent set of identifier parts.
	ConvertToString(String, array<Object[])	Converts a set of identifier parts into a formatted string identifier.
	ConvertToString(String, array<Object[], DataObjectIdentifierFormat)	Converts a set of identifier parts into a formatted string identifier, using the specified formatting option.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	FormatPart	Formats a specified identifier part.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnSiteChanged	Raises the SiteChanged event. (Inherited from DataSiteableObject<T>.)
	SplitIntoParts	Divides a string version of an identifier into a set of identifier parts converted into the expected format.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	UnformatPart	Removes formatting applied to a given identifier part.

Remarks

Typically, the identifier of an object on a data source consists of a string that is used in commands that get executed. For example, in the SQL statement SELECT * FROM mytable, the string mytable is the unique identifier of an object in the context under which the statement is running.

Typically a data source has some kind of containment mechanism for objects, such as a catalog, schema, or package. This introduces the need for multiple-part identifiers because a single name no longer suffices for uniquely identifying objects. For example, an Oracle server groups different objects under different users, causing the unique identifier of an object to be qualified with a user name.

Because the format of such multiple-part identifiers can vary from one data source to another, there has to be a way to convert a given string into its set of parts and vice versa. This class provides such a mechanism.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
