SkStreamSeekable is a SkStreamRewindable for which position, seek, move, and fork are required.
|
overridepure virtual |
Duplicates this stream.
If this cannot be done, returns NULL. The returned stream will be positioned at the beginning of its data.
Implements SkStreamRewindable.
Implemented in SkMemoryStream, SkFILEStream, SkStreamMemory, and SkStreamAsset.
|
overridepure virtual |
Duplicates this stream.
If this cannot be done, returns NULL. The returned stream will be positioned the same as this stream.
Reimplemented from SkStream.
Implemented in SkMemoryStream, SkFILEStream, SkStreamMemory, and SkStreamAsset.
|
overridepure virtual |
Returns the current position in the stream.
If this cannot be done, returns 0.
Reimplemented from SkStream.
Implemented in SkMemoryStream, and SkFILEStream.
|
inlineoverridevirtual |
Returns true if this stream can report it's current position.
Reimplemented from SkStream.
|
overridepure virtual |
Seeks to an relative offset in the stream.
If this cannot be done, returns false. If an attempt is made to move to a position outside the stream, the position will be set to the closest point within the stream (beginning or end).
Reimplemented from SkStream.
Implemented in SkMemoryStream, and SkFILEStream.
|
overridepure virtual |
Seeks to an absolute position in the stream.
If this cannot be done, returns false. If an attempt is made to seek past the end of the stream, the position will be set to the end of the stream.
Reimplemented from SkStream.
Implemented in SkMemoryStream, and SkFILEStream.
