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. |
