Supports the writing of a stream to a dynamic buffer. The stream does not take ownership of the dynamic buffer, which means that the creator is responsible for deleting the buffer when it is no longer needed.
See also: TBufBuf RWriteStream
| RBufWriteStream | ( | ) | [inline] |
Default constructor. Constructs an empty write stream object.
Call Open(), Truncate() or Insert() to prepare a stream for writing.
| RBufWriteStream | ( | const MExternalizer< TStreamRef > & | anExter | ) | [inline] |
Constructs a write stream with an externalizer. For example, CStoreMap implements MExternalizer<TStreamRef>.
See also: MExternalizer CStoreMap
| Parameter | Description |
|---|---|
| anExter | Specifies an externalizer. |
Constructs the RBufWriteStream object and opens a stream that writes to the specified dynamic buffer using the Open() function.
See also: RBufWriteStream::Open
| Parameter | Description |
|---|---|
| aBuf | The dynamic buffer hosting the stream. |
| aPos | The offset within the dynamic buffer where the stream is to start. Defaults to zero, if not explicitly specified. The value cannot be greater than the current size of the buffer, otherwise a E32USER-CBase 5 panic will be raised when streaming starts. |
| void | Append | ( | CBufBase & | aBuf | ) | [inline] |
Open a stream that writes to the dynamic buffer specified in the aBuf argument using insert mode.
See also: RBufWriteStream::Insert
| Parameter | Description |
|---|---|
| aBuf | The dynamic buffer that will be the source of this stream. |
Open a stream that writes into the dynamic buffer specified in the aBuf argument using insert mode.
See also: TBufBuf::Set TBufBuf::EInsert RWriteStream::Attach
| Parameter | Description |
|---|---|
| aBuf | The dynamic buffer hosting the stream. |
| aPos | The offset within the dynamic buffer where the stream is to start. Defaults to zero, if not explicitly specified. The value cannot be greater than the current size of the buffer, otherwise a E32USER-CBase 5 panic will be raised when streaming starts. |
Open a stream that writes to the dynamic buffer specified in the aBuf argument.
To close the stream and free its resources call Close()

| Parameter | Description |
|---|---|
| aBuf | The dynamic buffer hosting the stream. |
| aPos | The offset within the dynamic buffer where the stream is to start. Defaults to zero, if not explicitly specified. The value cannot be greater than the current size of the buffer, otherwise a E32USER-CBase 5 panic will be raised when streaming starts. |
Open a stream that writes into the dynamic buffer specified in the aBuf argument using truncate mode.

| Parameter | Description |
|---|---|
| aBuf | The dynamic buffer hosting the stream. |
| aPos | The offset within the dynamic buffer where the stream is to start. Defaults to zero, if not explicitly specified. The value cannot be greater than the current size of the buffer, otherwise a E32USER-CBase 5 panic will be raised when streaming starts. |
