| <H4 class="dtH4">Thread Safety</H4> |
| <P>Public static (<b>Shared</b> in Visual Basic) members of this type are |
| safe for multithreaded operations. Instance members are <b>not</b> guaranteed to be |
| thread-safe.</P> |
| <h4 class="dtH4">Remarks</h4> |
| <p> A configured component that interacts with potentially protected system resources uses a <a href="log4net.Core.SecurityContext.html">SecurityContext</a> to provide the elevated privileges required. If the <b>SecurityContext</b> object has been not been explicitly provided to the component then the component will request one from this <b>SecurityContextProvider</b>. </p> |
| <p> By default the <a href="log4net.Core.SecurityContextProvider.DefaultProvider.html">DefaultProvider</a> is an instance of <b>SecurityContextProvider</b> which returns only <a href="log4net.Util.NullSecurityContext.html">NullSecurityContext</a> objects. This is a reasonable default where the privileges required are not know by the system. </p> |
| <p> This default behavior can be overridden by subclassing the <b>SecurityContextProvider</b> and overriding the <a href="log4net.Core.SecurityContextProvider.CreateSecurityContext.html">CreateSecurityContext</a> method to return the desired <b>SecurityContext</b> objects. The default provider can be replaced by programmatically setting the value of the <b>DefaultProvider</b> property. </p> |
| <p> An alternative is to use the <code>log4net.Config.SecurityContextProviderAttribute</code> This attribute can be applied to an assembly in the same way as the <code>log4net.Config.XmlConfiguratorAttribute"</code>. The attribute takes the type to use as the <b>SecurityContextProvider</b> as an argument. </p> |
