MetadataPackage
The WavPackage type exposes the following members:
Constructors
| Constructor | Description |
|---|---|
__init__(self) |
Initializes a new instance of the WavPackage class. |
Properties
| Property | Description |
|---|---|
| metadata_type | Gets the metadata type. |
| keys | Gets a collection of the metadata property names. |
| property_descriptors | Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine. |
| count | Gets the number of metadata properties. |
| audio_format | Gets the audio format.
PCM = 1 (i.e. Linear quantization). Values other than 1 indicate some form of compression. |
| number_of_channels | Gets the number of channels. |
| sample_rate | Gets the sample rate. |
| byte_rate | Gets the byte rate. |
| block_align | Gets the block align. |
| bits_per_sample | Gets the bits per sample value. |
Methods
| Method | Description |
|---|---|
contains(self, property_name) |
Determines whether the package contains a metadata property with the specified name. |
find_properties(self, specification) |
Finds the metadata properties satisfying a specification.
The search is recursive so it affects all nested packages as well. |
update_properties(self, specification, value) |
Updates known metadata properties satisfying a specification.
The operation is recursive so it affects all nested packages as well. |
remove_properties(self, specification) |
Removes metadata properties satisfying a specification. |
add_properties(self, specification, value) |
Adds known metadata properties satisfying the specification.
The operation is recursive so it affects all nested packages as well. |
set_properties(self, specification, value) |
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(self) |
Removes writable metadata properties from the package.
The operation is recursive so it affects all nested packages as well. |
