Handlers are the things that do all the hard work in uSync. A Handler manages the import, export and saving of items to and from Umbraco.

By default, there are handlers for all the things in Umbraco:

<Handlers Group="default" EnableMissing="true">
    <HandlerConfig Name="uSync: DataTypeHandler" Enabled="true" />
    <HandlerConfig Name="uSync: TemplateHandler" Enabled="true" />
    <HandlerConfig Name="uSync: ContentTypeHandler" Enabled="true" />
    <HandlerConfig Name="uSync: MediaTypeHandler" Enabled="true" />
    <HandlerConfig Name="uSync: LanguageHandler" Enabled="true" />
    <HandlerConfig Name="uSync: DictionaryHandler" Enabled="true" />
    <HandlerConfig Name="uSync: MacroHandler" Enabled="true" />
    <HandlerConfig Name="uSync: DataTypeMappingHandler" Enabled="true" />
    <HandlerConfig Name="uSync: MemberTypeHandler" Enabled="false" />

Note: Handlers are enabled by default so if a handler exists on disk but isn't in the config it will be enabled by default

Enabling Handlers

Turning a handler on or off is as simple as setting Enabled="true" or Enabled="false" in the config.

Enabling for actions

In uSync 3.2.2. you can now enable or disable handlers for each of the actions they perform.

By default, handlers manage import, export and save events for each type of items.

You can now turn each of these on/off individually using the Actions="" attribute.

Actions="All" is the default, meaning a handler does all three things.

Possible settings are: any combination of All,Import,Export,Events

for example, if you want to have the DictionaryHandler only manage exports

<HandlerConfig Name="uSync: DictionaryHandler" Enabled="true" Actions="Export"/>

Handler Groups

Handlers can also be grouped. with the Group="" setting.

Note: at this time uSync only processes the Default group - this setting is for future enhancements
