Macro Definition Documentation

#define TT_ALIGN_16 __attribute__((aligned (16)))

Supress warnings about use of deprecated methods.

This macro should be defined at the top of a file before any includes in order to be made active. In general, the use of this macro should be viewed with suspicion. If it used a comment should accompany its use to explain the special situation that warrants the usage.

Definition at line 157 of file TTBase.h.

Typedef Documentation

typedef std::atomic<int32_t> TTAtomicInt

An integer that can be used for atomic operations.

Definition at line 243 of file TTBase.h.

typedef void(* TTFunctionMatch) (const TTValue &valueToCheck, TTPtr baton, TTBoolean &found)

Use for finding stuff in a list or a hash or a dictionary.

Definition at line 262 of file TTBase.h.

typedef void(* TTFunctionPtr) ()

A simple/generic function pointer with no args.

Definition at line 252 of file TTBase.h.

typedef void(* TTFunctionWithArgPtr) (TTPtr)

A simple/generic function pointer with one arg.

Definition at line 255 of file TTBase.h.

typedef TTErr(* TTFunctionWithBatonAndValue) (const TTValue &, const TTValue &)

A simple/generic function pointer with a baton as TTValueRef and the value to send back as a TTValueRef.

Definition at line 361 of file TTBase.h.

typedef void* TTPtr

A generic pointer.

Definition at line 248 of file TTBase.h.

typedef long TTPtrSizedInt

An integer that is the same size as a pointer.

Definition at line 240 of file TTBase.h.

typedef TTFloat64 TTSampleValue

A value representing a single audio sample.

TTSampleValue should be used any place a sample value is what the value represents. This will enable us to change the type in the future if needed. For example, to use 64-bit floats.

Definition at line 230 of file TTBase.h.

typedef std::vector<TTSampleValue> TTSampleVector

A TTSampleVector is simply a pointer to the first of an array of TTSampleValues.

Definition at line 233 of file TTBase.h.

Function Documentation

void TTFOUNDATION_EXPORT TTFree16 ( TTPtr ptr )

Free memory allocated using TTMalloc16().

Definition at line 647 of file TTBase.cpp.

Referenced by TTAudioSignal::alloc(), TTAudioSignal::allocWithNewChannelCount(), TTElement::operator delete(), TTAudioUnit::processAudio(), and TTAudioSignal::setVector().

TTFloat64 TTGetTimeInMicroseconds ( )

inline

Return the current system time in microseconds.

Definition at line 445 of file TTBase.h.

Referenced by TTDataObjectBase::calculate(), and TTAudioObjectBase::process().

TTFloat64 TTGetTimeInMilliseconds ( )

inline

Return the current system time in milliseconds.

Although it is a global kind of function, we include it as a method of TTBase so that it can be defined in the header file and then inlined in other libraries.
