Detailed Description
An implementation of Print that writes to an in-memory buffer.
The buffer can be retrieved using getBuffer() to verify that the expected string was written to the Print object.
Usage:
* {
* FakePrint fakePrint;
* object.printTo(fakePrint);
* assertEqual("expected", fakePrint.getBuffer());
* fakePrint.flush();
* ...
* }
* The internal buffer size is just big enough to hold a long long (8 bytes) with 3 bytes to hold the \\r\\n from a println() statement and the terminating NUL character.
This class is an early version of the PrintStr class of the AceCommon library. We don't want to change AUnit to use PrintStr instead because we use AUnit to write the unit tests for AceCommon itself, and it would cause a conceptual cyclic dependency. Also we want AUnit to be self-contained without additional dependencies.

◆ getBuffer()
|
inline |
Return the NUL terminated string buffer.
After the buffer is no longer needed, the flush() method should be called to reset the internal buffer index to 0.

Member Data Documentation
◆ kBufSize
|
static |
Size of the internal buffer.
This is just large enough to hold the string representation of one 64-bit integer in binary format (64 bytes), including 2 bytes for the '\r\n' from println() and 1 byte for the terminating NUL.
