## Detailed Description

An iterator to move over contiguous raw MIDI data, which Allows iterating over a MidiBuffer using C++11 range-for syntax.

In the following example, we log all three-byte messages in a midi buffer.

void processBlock (AudioBuffer<float>&, MidiBuffer& midiBuffer) override
{
for (const MidiMessageMetadata metadata : midiBuffer)
if (metadata.numBytes == 3)
Logger::writeToLog (metadata.getMessage().getDescription());
}

## Constructor & Destructor Documentation

## MidiBufferIterator()

juce::MidiBufferIterator::MidiBufferIterator | ( | const uint8 * | dataIn | ) |

inline explicit noexcept

Constructs an iterator pointing at the message starting at the byte dataIn. dataIn must point to the start of a valid MIDI message. If it does not, calling other member functions on the iterator will result in undefined behaviour.

Definition at line 90 of file juce_MidiBuffer.h.

## Member Function Documentation

## operator!=()

bool juce::MidiBufferIterator::operator!= | ( | const MidiBufferIterator & | other | ) | const

inline noexcept

Return false if this iterator points to the same message as another iterator instance, otherwise returns true.

Definition at line 117 of file juce_MidiBuffer.h.

## operator*()

MidiBufferIterator::reference juce::MidiBufferIterator::operator* | ( |  | ) | const

noexcept

Return an instance of MidiMessageMetadata which describes the message to which the iterator is currently pointing.

Definition at line 96 of file juce_MidiBuffer.cpp.

## operator++() [1/2]

MidiBufferIterator & juce::MidiBufferIterator::operator++ | ( |  | ) |

noexcept

Make this iterator point to the next message in the buffer.

Definition at line 83 of file juce_MidiBuffer.cpp.

## operator++() [2/2]

MidiBufferIterator juce::MidiBufferIterator::operator++ | ( | int |  | ) |

noexcept

Create a copy of this object, make this iterator point to the next message in the buffer, then return the copy.

Definition at line 89 of file juce_MidiBuffer.cpp.

## operator==()

bool juce::MidiBufferIterator::operator== | ( | const MidiBufferIterator & | other | ) | const

inline noexcept

Return true if this iterator points to the same message as another iterator instance, otherwise return false.
