Class UnityPersistenceBackendActivator

Constructs the PersistenceInstaller configured on a UnityPersistenceBackendDefinition via reflection. Never throws: any resolution or construction failure is logged and reported as a failed TryCreate(UnityPersistenceBackendDefinition, string, string, ILogService, out PersistenceInstaller) call, so callers can fall back to the built-in file backend.

Syntax

public static class UnityPersistenceBackendActivator

Methods

TryCreate(UnityPersistenceBackendDefinition, string, string, ILogService, out PersistenceInstaller)

Attempts to construct the installer described by definition.

Declaration

public static bool TryCreate(UnityPersistenceBackendDefinition definition, string companyName, string productName, ILogService logService, out PersistenceInstaller installer)

Parameters

Type	Name	Description
UnityPersistenceBackendDefinition	definition	The backend definition to activate.
string	companyName	The running app's company name, used when PassCompanyAndProduct is set.
string	productName	The running app's product name, used when PassCompanyAndProduct is set.
ILogService	logService	Log service used to report resolution or construction failures.
PersistenceInstaller	installer	The constructed installer, or null on failure.

Returns

Type	Description
bool	True if the installer was constructed successfully; otherwise false.

UnwrapInvocationException(Exception)

Returns the real failure behind a reflection call: the inner exception when exception is a TargetInvocationException wrapper, the exception itself otherwise. Public because UnitySerenityInstaller.InstallPersistence applies the same unwrap rule when a custom backend's Install throws.

Declaration

public static Exception UnwrapInvocationException(Exception exception)

Parameters

Type	Name	Description
Exception	exception	The caught exception, possibly a reflection wrapper.

Returns

Type	Description
Exception	The root-cause exception to log.
