Methods

Method Description
contains Determines whether the package contains a metadata property with the specified name.
find_properties Finds the metadata properties satisfying a specification.
The search is recursive so it affects all nested packages as well.
update_properties Updates known metadata properties satisfying a specification.
The operation is recursive so it affects all nested packages as well.
remove_properties Removes metadata properties satisfying a specification.
add_properties Adds known metadata properties satisfying the specification.
The operation is recursive so it affects all nested packages as well.
set_properties Sets known metadata properties satisfying the specification.
The operation is recursive so it affects all nested packages as well.
This method is a combination of MetadataPackage.add_properties and MetadataPackage.update_properties.
If an existing property satisfies the specification its value is updated.
If there is a known property missing in the package that satisfies the specification it is added to the package.
sanitize Removes writable metadata properties from the package.
The operation is recursive so it affects all nested packages as well.
