The ZstdRootPackage type exposes the following members:
| Method | Description |
|---|---|
| add_properties | Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. (inherited from MetadataPackage) |
| add_properties_func | (inherited from MetadataPackage) |
| contains | Returns True if the package contains a metadata property with the specified name; otherwise, False. (inherited from MetadataPackage) |
| contains_file | (inherited from MetadataPackage) |
| contains_string | (inherited from MetadataPackage) |
| find_properties | Finds metadata properties that satisfy the specified predicate, searching recursively through all nested packages. (inherited from MetadataPackage) |
| find_properties_func | (inherited from MetadataPackage) |
| get | (inherited from MetadataPackage) |
| get_enumerator | Returns an enumerator that iterates through the collection. (inherited from MetadataPackage) |
| get_file | (inherited from MetadataPackage) |
| get_string | (inherited from MetadataPackage) |
| remove_properties | Removes metadata properties satisfying the specified predicate. (inherited from MetadataPackage) |
| remove_properties_func | (inherited from MetadataPackage) |
| sanitize | Removes writable metadata properties from the package recursively, affecting all nested packages as well. (inherited from RootMetadataPackage) |
| set_properties | Sets known metadata properties satisfying the specified predicate. (inherited from MetadataPackage) |
| set_properties_func | (inherited from MetadataPackage) |
| update_properties | Updates known metadata properties that satisfy the specified predicate, recursively affecting all nested packages. (inherited from MetadataPackage) |
| update_properties_func | (inherited from MetadataPackage) |
| Property | Description |
|---|---|
| zstd_package | The ZSTD metadata package. |
| count | The number of metadata properties. (inherited from MetadataPackage) |
| file_type | The file type metadata package. (inherited from RootMetadataPackage) |
| keys | The collection of metadata property names. (inherited from MetadataPackage) |
| know_property_descriptors | The collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine. (inherited from MetadataPackage) |
| metadata_type | The metadata type of the package. (inherited from MetadataPackage) |
| property_descriptors | The collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine. (inherited from MetadataPackage) |
