Member Function Documentation

◆ allDependenciesDone()

void QQmlTypeData::allDependenciesDone ( )
overrideprotectedvirtual

Called when all blobs waited for have completed.

This occurs regardless of whether they are in error, or complete state.

The default implementation does nothing.

Reimplemented from QQmlDataBlob.

Definition at line 872 of file qqmltypedata.cpp.

◆ backupSourceCode()

SourceCodeData QQmlTypeData::backupSourceCode ( ) const
inline

Definition at line 64 of file qqmltypedata_p.h.

◆ compilationUnit()

QV4::CompiledData::CompilationUnit * QQmlTypeData::compilationUnit ( ) const

Definition at line 49 of file qqmltypedata.cpp.

◆ dataReceived()

void QQmlTypeData::dataReceived ( const SourceCodeData & )
overrideprotectedvirtual

Invoked when data for the blob is received.

Implementors should use this callback to determine a blob's dependencies. Within this callback you may call setError() or addDependency().

Implements QQmlDataBlob.

Definition at line 717 of file qqmltypedata.cpp.

◆ done()

void QQmlTypeData::done ( )
overrideprotectedvirtual

Invoked once data has either been received or a network error occurred, and all dependencies are complete.

You can set an error in this method, but you cannot add new dependencies. Implementors should use this callback to finalize processing of data.

The default implementation does nothing.

XXX Rename processData() or some such to avoid confusion between done() (processing thread) and completed() (main thread)

Reimplemented from QQmlDataBlob.

Definition at line 523 of file qqmltypedata.cpp.

◆ initializeFromCachedUnit()

void QQmlTypeData::initializeFromCachedUnit ( const QQmlPrivate::CachedQmlUnit * unit)
