Properties

Procedures

• CreateZipArchive(): Creates a new ZipArchive instance.
• OpenZipArchive(InputInStream: InStream; OpenForUpdate: Boolean): Creates a ZipArchive instance from the given InStream.
• OpenZipArchive(InputInStream: InStream; OpenForUpdate: Boolean; EncodingCodePageNumber: Integer): Creates a ZipArchive instance from the given InStream.
• OpenZipArchive(TempBlob: Codeunit "Temp Blob"; OpenForUpdate: Boolean): Creates a ZipArchive instance from the given instance of Temp Blob codeunit.
• SaveZipArchive(OutputOutStream: OutStream): Saves the ZipArchive to the given OutStream.
• SaveZipArchive(var TempBlob: Codeunit "Temp Blob"): Saves the ZipArchive to the given instance of Temp Blob codeunit.
• CloseZipArchive(): Disposes the ZipArchive.
• GetEntryList(var EntryList: List of [Text]): Returns the list of entries for the ZipArchive.
• ExtractEntry(EntryName: Text; OutputOutStream: OutStream; var EntryLength: Integer) (obsolete 23.0: This function has been replaced by the function ExtractEntry(EntryName: Text; OutputOutStream: OutStream) which instead returns the entry length.): Extracts an entry from the ZipArchive.
• ExtractEntry(EntryName: Text; OutputOutStream: OutStream): Integer: Extracts an entry from the ZipArchive.
• ExtractEntry(EntryName: Text; var TempBlob: Codeunit "Temp Blob"): Integer: Extracts an entry from the ZipArchive to a TempBlob instance.
• AddEntry(InStreamToAdd: InStream; PathInArchive: Text): Adds an entry to the ZipArchive.
• RemoveEntry(PathInArchive: Text): Removes an entry from the ZipArchive.
• IsGZip(InStream: InStream): Boolean: Determines whether the given InStream is compressed with GZip.
• IsZip(InStream: InStream): Boolean: Determines whether the given InStream is compressed with Zip.
• GZipCompress(InputInStream: InStream; CompressedOutStream: OutStream): Compresses a stream with GZip algorithm. The InStream that contains the content that should be compressed. The OutStream into which the compressed stream is copied to.
• GZipDecompress(InputInStream: InStream; DecompressedOutStream: OutStream): Decompresses a GZipStream. The InStream that contains the content that should be decompressed. The OutStream into which the decompressed stream is copied to.

Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an Object::"Name" argument. Interface dispatch and calls through events are not counted, so the list is not complete.

Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: bcatlas_resolve_node(object_type: "codeunit", object_name: "Data Compression"), then bcatlas_get_procedure_body or bcatlas_get_neighbors on the returned id.
