heapCreateValueType()

void * QQmlValueTypeProvider::heapCreateValueType ( const QQmlType & targetType, const QV4::Value & source )

static

Specialization that constructs the value type on the heap using new and returns a pointer to it.

populateValueType() [1/2]

bool QQmlValueTypeProvider::populateValueType ( QMetaType targetMetaType, void * target, const QV4::Value & source )

static

Populate the value type in place at target, which is expected to be allocated and default-constructed, for example the result of a QVariant(QMetaType). This is efficient if we can do byProperties() since it can use the pre-constructed object. It also avoids the creation of a QVariant in most cases. It is not efficient if you're going to create a QVariant anyway.
