C++ (Cpp) DataChunk::getSize Examples

Example #1

File: testsDataChunk.cpp Project: cyrinux/eguan

TEST_F(testsDataChunk, DefaultConstructor) {
    DataChunk empty;
    EXPECT_TRUE(empty.isReferencing(NULL));
    EXPECT_TRUE(empty.getData() == NULL);
    EXPECT_TRUE(empty.getSize() == 0);
    DataChunk emptyRef;
    emptyRef.reference(empty);
    EXPECT_TRUE(emptyRef.isReferencing(NULL));
    EXPECT_TRUE(emptyRef.getData() == NULL);
    EXPECT_TRUE(emptyRef.getSize() == 0);
    EXPECT_TRUE(emptyRef == empty);
}

Example #2

File: DiskreteEffect.cpp Project: ReDetection/sound-processor

    unsigned short bytePerSample=samples.getFormat()->bitsPerSample()/8;
    unsigned int count=samples.getSize()/bytePerSample; //samples count
    char *data8 = samples.getData();

            break;
        case 2:
