SzCoreConfig.hpp

Go to the documentation of this file.

// SzCoreConfig.hpp -- native-backed SzConfig implementation.
//
// Ports core/SzCoreConfig.cs. An SzCoreConfig is an in-memory configuration
// document, represented (as in C#) by its exported JSON config definition
// string rather than a live native handle. Each mutating/reading operation
// loads the definition into a native config handle (SzConfig_load_helper),
// performs the work, re-exports the (possibly updated) definition, and closes
// the handle. Native config handles are freed by SzConfig_close_helper, NOT
// SzHelper_free; a RAII guard guarantees the handle always closes.
//
// Constructed only by SzCoreConfigManager (obtain via
// SzConfigManager::CreateConfig); not constructed directly by SDK users.
