示例1: create
RefPtr<WebCore::SharedBuffer> WebPlatformStrategies::readBufferFromPasteboard(int index, const String& pasteboardType)
{
SharedMemory::Handle handle;
uint64_t size = 0;
WebProcess::singleton().parentProcessConnection()->sendSync(Messages::WebPasteboardProxy::ReadBufferFromPasteboard(index, pasteboardType), Messages::WebPasteboardProxy::ReadBufferFromPasteboard::Reply(handle, size), 0);
if (handle.isNull())
return nullptr;
RefPtr<SharedMemory> sharedMemoryBuffer = SharedMemory::map(handle, SharedMemory::Protection::ReadOnly);
return SharedBuffer::create(static_cast<unsigned char *>(sharedMemoryBuffer->data()), size);
}示例2: create
PassRefPtr<WebCore::SharedBuffer> WebPlatformStrategies::bufferForType(const String& pasteboardType, const String& pasteboardName)
{
SharedMemory::Handle handle;
uint64_t size = 0;
WebProcess::shared().connection()->sendSync(Messages::WebContext::GetPasteboardBufferForType(pasteboardName, pasteboardType),
Messages::WebContext::GetPasteboardBufferForType::Reply(handle, size), 0);
if (handle.isNull())
return 0;
RefPtr<SharedMemory> sharedMemoryBuffer = SharedMemory::create(handle, SharedMemory::ReadOnly);

}示例3: adoptVector
RefPtr<WebCore::SharedBuffer> WebPlatformStrategies::bufferForType(const String& pasteboardType, const String& pasteboardName)
{
// First check the overrides.
Vector<char> overrideBuffer;
if (WebPasteboardOverrides::sharedPasteboardOverrides().getDataForOverride(pasteboardName, pasteboardType, overrideBuffer))
return SharedBuffer::adoptVector(overrideBuffer);
// Fallback to messaging the UI process for native pasteboard content.
SharedMemory::Handle handle;
uint64_t size = 0;
