class HeapBuffered

Defined at line 135 of file ../../third_party/perfetto/include/perfetto/protozero/scattered_heap_buffer.h

Helper function to create heap-based protozero messages in one line.

Useful when manually serializing a protozero message (primarily in

tests/utilities). So instead of the following:

protozero::MyMessage msg;

protozero::ScatteredHeapBuffer shb;

protozero::ScatteredStreamWriter writer(

&shb

);

shb.set_writer(

&writer

);

msg.Reset(

&writer

);

...

You can write:

protozero::HeapBuffered

<protozero

::MyMessage> msg;

msg->set_stuff(...);

msg.SerializeAsString();

Public Methods

void HeapBuffered<T> ()

Defined at line 137 of file ../../third_party/perfetto/include/perfetto/protozero/scattered_heap_buffer.h

void HeapBuffered<T> (size_t initial_slice_size_bytes, size_t maximum_slice_size_bytes)

Defined at line 138 of file ../../third_party/perfetto/include/perfetto/protozero/scattered_heap_buffer.h

void HeapBuffered<T> (const HeapBuffered<T> & )

This can't be neither copied nor moved because Message hands out pointers

to itself when creating submessages.

reusable.
