Member Function Documentation

◆ constructValueType()

QVariant QQmlValueTypeProvider::constructValueType ( QMetaType targetMetaType,
const QMetaObject * targetMetaObject,
int ctorIndex,
void ** args )
static

Definition at line 798 of file qqmlglobal.cpp.

◆ createValueType() [1/4]

QVariant QQmlValueTypeProvider::createValueType ( const QJSValue & s,
QMetaType metaType )
static

Definition at line 819 of file qqmlglobal.cpp.

◆ createValueType() [2/4]

QVariant QQmlValueTypeProvider::createValueType ( const QString & s,
QMetaType metaType )
static

Definition at line 826 of file qqmlglobal.cpp.

◆ createValueType() [3/4]

QVariant QQmlValueTypeProvider::createValueType ( const QV4::Value & s,
QMetaType metaType,
QV4::ExecutionEngine * engine )
static

Definition at line 842 of file qqmlglobal.cpp.

◆ createValueType() [4/4]

QVariant QQmlValueTypeProvider::createValueType ( const QVariant & s,
QMetaType metaType,
QV4::ExecutionEngine * engine )
static

This should only be called with either builtin types or wrapped QJSValues as source.

Definition at line 888 of file qqmlglobal.cpp.

◆ heapCreateValueType()

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

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

Definition at line 776 of file qqmlglobal.cpp.

◆ populateValueType() [1/2]

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

◆ populateValueType() [2/2]

bool QQmlValueTypeProvider::populateValueType ( QMetaType targetMetaType,
void * target,
QMetaType sourceMetaType,
void * source,
