IRecordSequence.Append Method

Definition

When overridden in a derived class, writes a log record to the IRecordSequence.

Overloads

Append(ArraySegment<Byte>, SequenceNumber, SequenceNumber, RecordAppendOptions)

When overridden in a derived class, writes a log record to the IRecordSequence.

Append(IList<ArraySegment<Byte>>, SequenceNumber, SequenceNumber, RecordAppendOptions)

When overridden in a derived class, appends a log record to the IRecordSequence.

Append(ArraySegment<Byte>, SequenceNumber, SequenceNumber, RecordAppendOptions, ReservationCollection)

When overridden in a derived class, appends a log record to the IRecordSequence, using space previously reserved in the sequence.

Append(IList<ArraySegment<Byte>>, SequenceNumber, SequenceNumber, RecordAppendOptions, ReservationCollection)

When overridden in a derived class, appends a log record to the IRecordSequence, using space previously reserved in the sequence.

Append(ArraySegment<Byte>, SequenceNumber, SequenceNumber, RecordAppendOptions)

When overridden in a derived class, writes a log record to the IRecordSequence.

public:
 System::IO::Log::SequenceNumber Append(ArraySegment<System::Byte> data, System::IO::Log::SequenceNumber nextUndoRecord, System::IO::Log::SequenceNumber previousRecord, System::IO::Log::RecordAppendOptions recordAppendOptions);
public System.IO.Log.SequenceNumber Append (ArraySegment<byte> data, System.IO.Log.SequenceNumber nextUndoRecord, System.IO.Log.SequenceNumber previousRecord, System.IO.Log.RecordAppendOptions recordAppendOptions);
abstract member Append : ArraySegment<byte> * System.IO.Log.SequenceNumber * System.IO.Log.SequenceNumber * System.IO.Log.RecordAppendOptions -> System.IO.Log.SequenceNumber
Public Function Append (data As ArraySegment(Of Byte), nextUndoRecord As SequenceNumber, previousRecord As SequenceNumber, recordAppendOptions As RecordAppendOptions) As SequenceNumber

Parameters

data
ArraySegment<Byte>

A list of byte array segments that will be concatenated and appended as the record.

nextUndoRecord
SequenceNumber

The sequence number of the next record in the user-specified order.

previousRecord
SequenceNumber

The sequence number of the next record in Previous order.

recordAppendOptions
RecordAppendOptions

A valid value of RecordAppendOptions that specifies how the data should be written.

Returns

The sequence number of the appended log record.

Exceptions

One or more of the arguments is invalid.

An I/O error occurred while appending the record.

The record sequence could not make enough free space to contain the new record.

The method was called after the sequence has been disposed of.

Remarks

Data contained in the data parameter will be concatenated into a single byte array for appending as the record. However, no provision is made for splitting data back into array segments when the record is read.

Normally, this method completes before the record has been written. To ensure that a record has been written, either specify the ForceFlush flag using the recordAppendOptions parameter, or call the Flush method.

Applies to

Append(IList<ArraySegment<Byte>>, SequenceNumber, SequenceNumber, RecordAppendOptions)

When overridden in a derived class, appends a log record to the IRecordSequence.

abstract member Append : System.Collections.Generic.IList<ArraySegment<byte>> * System.IO.Log.SequenceNumber * System.IO.Log.SequenceNumber * System.IO.Log.RecordAppendOptions -> System.IO.Log.SequenceNumber
Public Function Append (data As IList(Of ArraySegment(Of Byte)), nextUndoRecord As SequenceNumber, previousRecord As SequenceNumber, recordAppendOptions As RecordAppendOptions) As SequenceNumber

Parameters

SequenceNumber

The sequence number of the next record in the user-specified order.

previousRecord
SequenceNumber

The sequence number of the next record in Previous order.

recordAppendOptions
RecordAppendOptions

A valid value of RecordAppendOptions that specifies how the data should be written.

Returns

The sequence number of the appended log record.

Exceptions

One or more of the arguments is invalid.

An I/O error occurred while appending the record.

The record sequence could not make enough free space to contain the new record.

The method was called after the sequence has been disposed of.

Remarks

Data contained in the data parameter will be concatenated into a single byte array for appending as the record. However, no provision is made for splitting data back into array segments when the record is read.

Applies to

Append(ArraySegment<Byte>, SequenceNumber, SequenceNumber, RecordAppendOptions, ReservationCollection)

When overridden in a derived class, appends a log record to the IRecordSequence, using space previously reserved in the sequence.

public:
 System::IO::Log::SequenceNumber Append(ArraySegment<System::Byte> data, System::IO::Log::SequenceNumber nextUndoRecord, System::IO::Log::SequenceNumber previousRecord, System::IO::Log::RecordAppendOptions recordAppendOptions, System::IO::Log::ReservationCollection ^ reservations);
public System.IO.Log.SequenceNumber Append (ArraySegment<byte> data, System.IO.Log.SequenceNumber nextUndoRecord, System.IO.Log.SequenceNumber previousRecord, System.IO.Log.RecordAppendOptions recordAppendOptions, System.IO.Log.ReservationCollection reservations);
abstract member Append : ArraySegment<byte> * System.IO.Log.SequenceNumber * System.IO.Log.SequenceNumber * System.IO.Log.RecordAppendOptions * System.IO.Log.ReservationCollection -> System.IO.Log.SequenceNumber
Public Function Append (data As ArraySegment(Of Byte), nextUndoRecord As SequenceNumber, previousRecord As SequenceNumber, recordAppendOptions As RecordAppendOptions, reservations As ReservationCollection) As SequenceNumber

Parameters

data
ArraySegment<Byte>

A list of byte array segments that will be concatenated and appended as the record.

nextUndoRecord
SequenceNumber

The sequence number of the next record in the user-specified order.

previousRecord
SequenceNumber

The sequence number of the next record in Previous order.

recordAppendOptions
RecordAppendOptions

A valid value of RecordAppendOptions that specifies how the data should be written.

reservations
ReservationCollection

A ReservationCollection that contains the reservation that should be used for this record.

Returns

The sequence number of the appended log record.

Exceptions

One or more of the arguments is invalid.

An I/O error occurred while appending the record.

The record sequence could not make enough free space to contain the new record.

The method was called after the sequence has been disposed of.

Remarks

Data contained in the data parameter will be concatenated into a single byte array for appending as the record. However, no provision is made for splitting data back into array segments when the record is read.

The appended record will consume space that has been previously reserved, using a reservation specified by the reservations parameter. If the append succeeds, it will consume the smallest reservation area that can hold the data, and that reservation area will be removed from the collection.

Normally, this method completes before the record has been written. To ensure that a record has been written, either specify the ForceFlush flag using the recordAppendOptions parameter, or call the Flush method.
