Methods

¶BufferWriter(uint64_t chunkSize = 0)

Declared at: mcap/include/mcap/writer.hpp:255

Parameters

uint64_t chunkSize = 0

¶const int* compressedData() const

Declared at: mcap/include/mcap/writer.hpp:264

¶uint64_t compressedSize() const

Description

Returns the size in bytes of the compressed data. This will only be called after `end()`.

Declared at: mcap/include/mcap/writer.hpp:260

¶const int* data() const

Declared at: mcap/include/mcap/writer.hpp:263

¶bool empty() const

Description

Returns true if `write()` has never been called since initialization or the last call to `clear()`.

Declared at: mcap/include/mcap/writer.hpp:261

¶void end()

Description

Called when the writer wants to close the current output Chunk. After this call, `data()` and `size()` should return the data and size of the compressed data.

Declared at: mcap/include/mcap/writer.hpp:258

¶void handleClear()

Declared at: mcap/include/mcap/writer.hpp:262

¶void handleWrite(const int* data, uint64_t size)

Declared at: mcap/include/mcap/writer.hpp:257

Parameters

const int* data

uint64_t size

¶uint64_t size() const

Description

Returns the size in bytes of the uncompressed data.
