Member Function Documentation

compileSource()

static PyObject * PythonQtImport::compileSource ( const QString &  path, const QByteArray &  data  )

static

Given a string buffer containing Python source code, compile it return and return a code object as a new reference.

getCacheFilename()

static QString PythonQtImport::getCacheFilename ( const QString &  sourceFile, bool  isOptimizedFilename  )

static

Returns the filename of the cache file for the given source file, e.g. test.pyc for test.py.

getCodeFromData()

static PyObject * PythonQtImport::getCodeFromData ( const QString &  path, int  isbytecode = 0, int  ispackage = 0, time_t  mtime = 0  )

static

Return the code object for the module named by 'fullname' from the Zip archive as a new reference.

getCodeFromPyc()

static PyObject * PythonQtImport::getCodeFromPyc ( const QString &  file )

static

gets the compiled code for the given *.py file if there is a valid pyc file, otherwise compiles the file and writes the pyc

getLong()

static long PythonQtImport::getLong ( unsigned char *  buf )

static

Given a buffer, return the long that is represented by the first 4 bytes, encoded as little endian. This partially reimplements marshal.c:r_long()

getModuleCode()

static PyObject * PythonQtImport::getModuleCode ( PythonQtImporter *  self, const char *  fullname, QString &  modpath, QString &  cachemodpath  )

static

Get the code object associated with the module specified by 'fullname'. In Python3, modpath will always be the path to the *.py file and cachemodpath the path to the *.pyc file (if it exists).

getModuleInfo()

static ModuleInfo PythonQtImport::getModuleInfo ( PythonQtImporter *  self, const QString &  fullname  )

static

Return if module exists and is a package or a module.

getMTimeOfSource()

static time_t PythonQtImport::getMTimeOfSource ( const QString &  path )

static

get time stamp of file

getSourceFilename()

static QString PythonQtImport::getSourceFilename ( const QString &  cacheFile )

static

Returns the filename of the source file for the given cache file, e.g. test.py for test.pyc.

getSubName()

static QString PythonQtImport::getSubName ( const QString &  str )

static

get the last name of a dot chain (first.second.last)

init()

static void PythonQtImport::init ( )

static

initialize

replaceExtension()

static QString PythonQtImport::replaceExtension ( const QString &  str, const QString &  ext  )

static

replace extension of file

unmarshalCode()

static PyObject * PythonQtImport::unmarshalCode ( const QString &  path, const QByteArray &  data, time_t  mtime  )

static

Given the contents of a .py[co] file in a buffer, unmarshal the data and return the code object. Return None if it the magic word doesn't match (we do this instead of raising an exception as we fall back to .py if available and we don't want to mask other errors). Returns a new reference.

writeCompiledModule()

static void PythonQtImport::writeCompiledModule ( PyCodeObject *  co, const QString &  filename, long  mtime, long  sourceSize  )

static

writes the python code to disk, marshalling and writing the time stamp
