Class LockTransactionResult

Represents a result of locking operation performed by ILockManager. If transaction selects some results then this class enumerates all key value pairs that may contain duplicate names

Constructors

LockTransactionResult(Guid, String, LockStatus, LockErrorCause, String, UInt32, Double, KeyValuePair<String, Object>[])

Declaration
public LockTransactionResult(Guid tranID, string server, LockStatus status, LockErrorCause errorCause, string failedStatement, uint runtimeSec, double trustLevel, KeyValuePair<string, object>[] data)
Parameters
Type Name Description
System.Guid tranID
System.String server
LockStatus status
LockErrorCause errorCause
System.String failedStatement
System.UInt32 runtimeSec
System.Double trustLevel
System.Collections.Generic.KeyValuePair<System.String, System.Object>[] data

Fields

ErrorCause

In case of error specifies the cause

Declaration
public readonly LockErrorCause ErrorCause
Field Value
Type Description
LockErrorCause

FailedStatement

Returns the description of failed statement or null if transactions succeeded

Declaration
public readonly string FailedStatement
Field Value
Type Description
System.String

ServerHost

Returns the host name of the host that serviced the call

Declaration
public readonly string ServerHost
Field Value
Type Description
System.String

ServerRuntimeSec

Returns for how many seconds the server has been running

Declaration
public readonly uint ServerRuntimeSec
Field Value
Type Description
System.UInt32

ServerTrustLevel

Returns the coefficient of trust 0..1(maximum) of the server state. The value is computed based on the length of server uninterrupted runtime. This value plays an important role in speculative locking when lock server crashes, the caller may examine this returned value and based on it reject the fact that lock was taken, or the caller may specify the LockTransaction.MinimumRequiredTrustLevel for the transaction to succeed

Declaration
public readonly double ServerTrustLevel
Field Value
Type Description
System.Double

Status

Returns the status of the call: whether call failed or transaction could not be executed

Declaration
public readonly LockStatus Status
Field Value
Type Description
LockStatus

TransactionID

Returns the original transaction ID

Declaration
public readonly Guid TransactionID
Field Value
Type Description
System.Guid

Properties

CallFailed

Declaration
public static LockTransactionResult CallFailed { get; }
Property Value
Type Description
LockTransactionResult

Count

Returns the count of returned variables

Declaration
public int Count { get; }
Property Value
Type Description
System.Int32

Item[String]

Returns the first variable value by case-sensitive name. The var names may not be unique, as they are added during tran execution. Use instance of this class to enumerate all key value pairs

Declaration
public object this[string var] { get; }
Parameters
Type Name Description
System.String var
Property Value
Type Description
System.Object
