InMemoryOpcPackage
Overview
InMemoryOpcPackage is a class in Aspose.Slides FOSS for C++.
In-memory OPC package with ZIP file I/O support. Manages an Open Packaging Conventions package as an in-memory map of part names to byte arrays. Supports loading from and saving to ZIP archives (file paths or streams), preserving unknown parts for round-trip fidelity.
This class provides 14 methods for working with InMemoryOpcPackage objects in C++ programs.
Available methods include: InMemoryOpcPackage, close, create_new, delete_part, get_part, get_part_names, has_part, open, save, set_part, source_path.
All public members are accessible to any C++ application after installing the Aspose.Slides FOSS for C++ package.
Methods
| Signature | Description |
|---|---|
InMemoryOpcPackage() | |
open(path: std::filesystem::path) → InMemoryOpcPackage | Open an OPC package from a file path. |
open(stream: std::istream) → InMemoryOpcPackage | Open an OPC package from a file path. |
create_new() → InMemoryOpcPackage | Create a new empty OPC package. |
save(path: std::filesystem::path) | Save the package to a file path as a ZIP archive. |
save(stream: std::ostream) | Save the package to a file path as a ZIP archive. |
get_part(part_name: std::string_view) → std::optional<std::vector<uint8_t>> | Retrieve a part’s content by name. Returns nullopt if the part does not exist. |
set_part(part_name: std::string_view, content: std::vector<uint8_t>) | Store (or overwrite) a part with the given content. |
set_part(part_name: std::string_view, content: std::string_view) | Store (or overwrite) a part with the given content. |
has_part(part_name: std::string_view) → bool | Check whether a part exists in the package. |
delete_part(part_name: std::string_view) → bool | Delete a part from the package. |
get_part_names() → std::vector<std::string> | Get a list of all part names in the package. |
source_path() → std::optional<std::string> | Get the original file path if the package was loaded from a file. |
close() | Close the package and release resources. Clears all in-memory part data. The package should not be used after closing. |
