Properties

Name Description
CompressionMethod { get; } Gets the algorithm used to compress the chunk data.
Count { get; } Gets the number of metadata properties.
IsCompressed { get; } Gets a value indicating whether the chunk is compressed.
Item { get; } Gets the MetadataProperty with the specified name.
Keys { get; } Gets a collection of the metadata property names.
Keyword { get; } Gets the keyword that indicates the type of information represented by the chunk.
Language { get; } Gets the human language used by the translated keyword and the text.
MetadataType { get; } Gets the metadata type.
PropertyDescriptors { get; } Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
Text { get; } Gets the actual text string represented by the chunk.
TranslatedKeyword { get; } Gets the translated keyword that contains a translation of the keyword into the language indicated by the language property.

Methods

Name Description
virtual AddProperties(Func<MetadataProperty, bool>, PropertyValue) Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
Contains(string) Determines whether the package contains a metadata property with the specified name.
virtual FindProperties(Func<MetadataProperty, bool>) Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well.
GetEnumerator() Returns an enumerator that iterates through the collection.
virtual RemoveProperties(Func<MetadataProperty, bool>) Removes metadata properties satisfying the specified predicate.
virtual Sanitize() Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
virtual SetProperties(Func<MetadataProperty, bool>, PropertyValue) Sets known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. This method is a combination of AddProperties and UpdateProperties. If an existing property satisfies the predicate its value is updated. If there is a known property missing in the package that satisfies the predicate it is added to the package.
virtual UpdateProperties(Func<MetadataProperty, bool>, PropertyValue) Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
