C++ (Cpp) MemoryBlock::getData Examples

Example #1

void AudioProcessor::copyXmlToBinary (const XmlElement& xml, juce::MemoryBlock& destData)
{
    const String xmlString (xml.createDocument (String::empty, true, false));
    const int stringLength = xmlString.getNumBytesAsUTF8();

    destData.setSize ((size_t) stringLength + 10);

    char* const d = static_cast<char*> (destData.getData());
    *(uint32*) d = ByteOrder::swapIfBigEndian ((const uint32) magicXmlNumber);
    *(uint32*) (d + 4) = ByteOrder::swapIfBigEndian ((const uint32) stringLength);

    xmlString.copyToUTF8 (d + 8, stringLength + 1);
}

Example #2

File: juce_AudioProcessor.cpp Project: eriser/rejuce

void AudioProcessor::copyXmlToBinary (const XmlElement& xml, juce::MemoryBlock& destData)
{
    const String xmlString (xml.createDocument (String::empty, true, false));
    const size_t stringLength = xmlString.getNumBytesAsUTF8();

    destData.setSize (stringLength + 9);

    uint32* const d = static_cast<uint32*> (destData.getData());
    d[0] = ByteOrder::swapIfBigEndian ((const uint32) magicXmlNumber);
    d[1] = ByteOrder::swapIfBigEndian ((const uint32) stringLength);

    xmlString.copyToUTF8 ((CharPointer_UTF8::CharType*) (d + 2), stringLength + 1);
}

Example #3

File: juce_AudioProcessor.cpp Project: LeapMotionRV/Badaboum

void AudioProcessor::copyXmlToBinary (const XmlElement& xml, juce::MemoryBlock& destData)
{
    {
        MemoryOutputStream out (destData, false);
        out.writeInt (magicXmlNumber);
        out.writeInt (0);
        xml.writeToStream (out, String::empty, true, false);
        out.writeByte (0);
    }

    // go back and write the string length..
    static_cast<uint32*> (destData.getData())[1]
        = ByteOrder::swapIfBigEndian ((uint32) destData.getSize() - 9);
