public final class SpaceCalcMessageTypeV1_0
extends SpaceCalcMessageType

The SpaceCalcMessageType is used for instructing the server monitor to do a space calculation on the passed-in parameters and return the results.

This message type has the following fields :

Field detail

Zone	Format	Length	Description
USERID	STRING		The name of the user issuing the monitor command. Can be the zero-length string, but if not, it must be a name that appears in some tuple of the USER relvar.
AUTHBYCLIENT	INTEGER	1	1 if the client has authenticated the user, 0 otherwise.
AUTHALGORITHM	STRING		The name of the signing algorithm used to compute SIGNATURE. Can be the zero-length string.
SIGNATURELENGTH	INTEGER	2	The number of bytes in SIGNATURE. Can be zero, in which case the SIGNATURE field is omitted from the message.
SIGNATURE	BYTES		The signature as computed by the signature algorithm identified by AUTHALGORITHM, using the user's private key corresponding to the public key that is registered for the user in the USERCERTIFICATE relvar, and applied to the CHALLENGE field obtained from the preceding ServerHello response message.
ENTRYTYPE	STRING		Indicator for the type of storage space for which the computation is done. Allowable values are TREE, HASH, DATA or MHSH.
ENTRYSIZE	INTEGER	4	The size of an individual entry (of the involved type) in the storage space. E.g. in a DATA space, the physical length of a record (the number of bytes occupied by the encoded attribute values) to be stored in it.
ENTRYCOUNT	INTEGER	8	The number of entries that the storage space is expected to be able to handle.
PAGESIZE	INTEGER	4	The size of the pages in the storage space.
GAPCOUNT	INTEGER	4	For DATA and MHSH storage space types, the number of physical gaps that are to be allowed to appear internally on the page before page compression is attempted.

Description copied from class: ExecuteCompiledMonitorCommandMessageType

Produces a CompiledMonitorCommandMessage of the appropriate type reflecting the given attribute values

Specified by:

message in class ExecuteCompiledMonitorCommandMessageType

Parameters:

commandParams - The command object's relevant params to be communicated in a message to the server

signature - The signature authenticating the user ID

userAuthenticationAlgorithm - Name of the Signature algorithm to be used when signing the user ID/verifying the userID signature

authenticatedByClient - true if the user has been authenticated by the client

userID - The ID of the user issuing the monitor command

Returns:

The ExecuteMonitorCommandMessage of the appropriate type reflecting the given attribute values
