LogRecord Class

.NET Framework (current version)

Represents an unstructured log record delivered as a COM+ CrmLogRecordRead structure. This class cannot be inherited.

Namespace: System.EnterpriseServices.CompensatingResourceManager
Assembly: System.EnterpriseServices (in System.EnterpriseServices.dll)

Inheritance Hierarchy

System::Object

Syntax

C++

public ref class LogRecord sealed

Properties

	Name	Description
	Flags	Gets a value that indicates when the log record was written.
	Record	Gets the log record user data.
	Sequence	The sequence number of the log record.

Methods

	Name	Description
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Unstructured log records are delivered as a COM+ CrmLogRecordRead structure. In addition to the user data (a single BLOB), this contains additional fields that are useful for debugging or fault finding. The Flags field is a bit field that provides further information about whether this record was forgotten at some point, and when it was written. The Sequence field provides the sequence number of the log record. In most cases, sequence numbers are sequential but are not necessarily contiguous due to internal log records that are not delivered to the Compensating Resource Manager (CRM) Compensator.

Examples

The following code example demonstrates the use of this class.

C++

public:
    virtual bool AbortRecord(LogRecord^ log) override
    {

        // Check the validity of the record.
        if (log == nullptr)
        {
            return true;
        }
        array<Object^>^ record = dynamic_cast<array<Object^>^>(log->Record);
        if (record == nullptr)
        {
            return true;
        }
        if (record->Length != 2)
        {
            return true;
        }

        // Extract old account data from the record.
        String^ filename = (String^) record[0];
        int balance = (int) record[1];

        // Restore the old state of the account.
        WriteAccountBalance(filename, balance);

        return false;
    }
