Online dirty chat rooms - Invalidating package

You can see the associated compiler error messages with the SQL*Plus command to recompile only the package specification, regardless of whether it is invalid.You might want to recompile a package specification to check for compilation errors after modifying the specification.To redeclare or redefine a package, use the CREATE PACKAGE Statement, or the CREATE PACKAGE BODY Statement with the keyword is required.

Note that the decorator will not work on static methods because of the assumption of two arguments.

The decorated method will take in the name of the module to be loaded as expected for a Note For projects where startup time is critical, this class allows for potentially minimizing the cost of loading a module if it is never used.

A dotted name does not have its parents implicitly imported as that requires loading them and that may not be desired.

To properly import a submodule you will need to import all parent packages of the submodule and use the correct argument to then it will be called to perform the invalidation.

For projects where startup time is not essential then use of this class is heavily discouraged due to error messages created during loading being postponed and thus occurring out of context. This example will show you how to register your own importers so that import will use them (for creating an importer for yourself, read the documentation for the appropriate classes defined within this package): Import itself is implemented in Python code, making it possible to expose most of the import machinery through importlib.

statement explicitly recompiles a package specification, body, or both.When writing to the path fails because the path is read-only (Returns a combined list of strings representing all file suffixes for modules recognized by the standard import machinery.This is a helper for code which simply needs to know if a filesystem path potentially refers to a module without needing any details on the kind of module (for example, argument is a variable number of 2-item tuples each containing a loader and a sequence of file suffixes the loader recognizes.The return value is the module object (which can be different if re-importing causes a different object to be placed in There are a number of other caveats: When a module is reloaded, its dictionary (containing the module’s global variables) is retained.Redefinitions of names will override the old definitions, so this is generally not a problem.If the new version of a module does not define a name that was defined by the old version, the old definition remains.
