◆ 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.
