Listeners receive notifications when entries in a region change, or when changes occur to the region attributes themselves. Entry events are `create`, `update`, `invalidate`, and `destroy`. Region events are `invalidate` and `destroy`. Multiple events can cause concurrent invocation of `ICacheListener` methods. If event A occurs before event B, there is no guarantee that their corresponding ICacheListener method invocations will occur in the same order. - - http://git-wip-us.apache.org/repos/asf/geode-native/blob/de0559be/geode-docs/nativeclient/dotnet-caching-api/extending-pdx-autoserializer.html.md.erb ---------------------------------------------------------------------- diff --git a/geode-docs/nativeclient/dotnet-caching-api/extending-pdx-autoserializer.html.md.erb b/geode-docs/nativeclient/dotnet-caching-api/extending-pdx-autoserializer.html.md.erb deleted file mode 100644 index bc1b765..0000000 --- a/geode-docs/nativeclient/dotnet-caching-api/extending-pdx-autoserializer.html.md.erb +++ /dev/null @@ -1,59 +0,0 @@ ---- -title: Extend the PDX Autoserializer ---- - -This example code demonstrates how to extend the autoserializer to customize serialization. - -## Extending the Autoserializer - -``` pre -public class AutoSerializerEx : ReflectionBasedAutoSerializer -{ - public override object WriteTransform(FieldInfo fi, Type type, object originalValue) { - if (fi.FieldType.Equals(Type.GetType("System.Guid"))) { - return originalValue.ToString(); - } else if (fi.FieldType.Equals(Type.GetType("System.Decimal"))) { - return originalValue.ToString(); - } else - return base.WriteTransform(fi, type, originalValue); - } - - public override object ReadTransform(FieldInfo fi, Type type, object serializeValue) { - if (fi.FieldType.Equals(Type.GetType("System.Guid"))) { - Guid g = new Guid((string)serializeValue); - return g; - } else if (fi.FieldType.Equals(Type.GetType("System.Decimal"))) { - return Convert.ToDecimal((string)serializeValue); - } else - return base.ReadTransform(fi, type, serializeValue); - } - - public override FieldType GetFieldType(FieldInfo fi, Type type) { - if (fi.FieldType.Equals(Type.GetType("System.Guid")) || - fi.FieldType.Equals(Type.GetType("System.Decimal"))) - return FieldType.STRING; - return base.GetFieldType(fi, type); - } - - public override bool IsIdentityField(FieldInfo fi, Type type) { - if (fi.Name == "_identityField") - return true; - return base.IsIdentityField(fi, type); - } - - public override string GetFieldName(FieldInfo fi, Type type) { - if (fi.Name == "_nameChange") - return fi.Name + "NewName"; - return fi.Name; - } - - public override bool IsFieldIncluded(FieldInfo fi, Type type) - { - if (fi.Name == "_notInclude") - return false; - return base.IsFieldIncluded(fi, type); - } -} -``` - - http://git-wip-us.apache.org/repos/asf/geode-native/blob/de0559be/geode-docs/nativeclient/dotnet-caching-api/how-igfserializable-works.html.md.erb ---------------------------------------------------------------------- diff --git a/geode-docs/nativeclient/dotnet-caching-api/how-igfserializable-works.html.md.erb b/geode-docs/nativeclient/dotnet-caching-api/how-igfserializable-works.html.md.erb deleted file mode 100644 index 55d7299..0000000 --- a/geode-docs/nativeclient/dotnet-caching-api/how-igfserializable-works.html.md.erb +++ /dev/null @@ -1,19 +0,0 @@ ---- -title: How Serialization Works with IGFSerializable ---- - -When your application puts an object into the cache for distribution, Geode serializes the data by taking these steps. - -1.

For example, if one appdomain calls `cache.close`, it closes the cache for the entire process. Any further cache access operations by the other appdomains return cache closed exceptions. - -**Resolution:** `Cache create`/`close` provides reference counting of `Cache` `create` and `close`.
