Interface Summary
Interface	Description
ActionProvider<T>	An `ActionProvider` usually performs a CRUD-action on a domain object.
ApplicationConfigProvider	Provides the basic configuration of a `Application`, which is the `ApplicationInfo` parsed from the `application-info.xml` and all defined `PageDefinition`s, `Event`s, `Action`s, `Datasource`s and also the `ApplicationRootConfig`.
ApplicationController	Provides methods to startup and shutdown a `Application`.
AttachmentWebservice	Enhancement of a `Webservice` which is used to provide a file as an attachment.
DataProvider	An `DataProvider` usually retrieves some data from the persistence layer and returns it as a `DataContainer`.
Environment	The `Environment` is able to set, read and remove attributes of a certain `Scope`.
FieldConverter	A `FieldConverter` is responsible for converting a property of an bindclass-instance to its `String`-representation inside of a `Datafield` (see `FieldConverter.setString(FieldWrapper)`) a parameter from a `RequestContainer` to its object-representation (see `FieldConverter.setObject(FieldWrapper, RequestContainer)`)
FieldProcessor	A `FieldProcessor` keeps track of the `MetaData` and `Linkpanel`s defined in the `DataConfig` of a `Datasource`.
FormProcessProvider	When using the appNG-Taglibrary to define a HTLM-form inside a JSP, a `FormProcessProvider` is used to handle the submitted data.
FormValidator	Interface that can be implemented by an `ActionProvider` or the formBean that is used by an `ActionProvider` .
GlobalTaglet	A `GlobalTaglet` is a specialized kind of a `Taglet`.
GlobalXMLTaglet	A `GlobalXMLTaglet` is a specialized kind of a `XMLTaglet`.
MessageParam	A `MessageParam` provides a message key and optionally some message arguments which can be used when formatting a message with `MessageFormat.format(String, Object...)`.
Option	A single option which was created from a `BeanOption` of a `Bean` .
Options	`Options` are created from the `BeanOption`s of a `Bean` and contain several `Option`s.
PageProcessor	Interface that optionally can be implemented by a `Taglet` `GlobalTaglet` `XMLTaglet` `GlobalXMLTaglet` If `PageProcessor.processPage()` returns `false`, the rest of the JSP-page will be skipped.
ParameterSupport	Supports finding and replacing parameters inside a `String`.
Path	A `Path` provides informations about the `Site` to which the current `HttpServletRequest` belongs to.
PermissionProcessor	Checks the `Permission`s owned by a `PermissionOwner`.
Request	A `Request` is the framework-internal representation of a `HttpServletRequest`, wrapping the afore mentioned and adding framework-specific methods.
RequestSupport	Provides commonly used methods for supporting request-processing and filling bindobjects.
ResultService	Provides methods to transform a bindobject to a `Result` and a `Page` of bindobjects to a `Resultset`.
ScheduledJob	A `ScheduledJob` is a (periodically or manually triggered) task that can be defined by an `Application`.
SoapService	This interface has to be implemented for creating SOAP-webservices based on JAXB and Spring-WS.
Taglet	A `Taglet` can be used inside a JSP-Page to embed (static or dynamic) content that is retrieved from a `Application`. A `Taglet` is used as follows (`method` refers to bean name of the implementing class):
ValidationProvider	Provides some validation-related methods.
Webservice	A `Webservice` usually returns some text-based data like XML, JSON or even plain text, which can directly be displayed/processed by the client.
XMLTaglet	Similar to a `Taglet`, a `XMLTaglet` can be used inside a JSP-Page to embed (static or dynamic) content that is retrieved from a `Application`.

Class Summary
Class	Description
DataContainer	A container for the data returned by a `DataProvider`.
FieldConverter.DatafieldOwner	A `DatafieldOwner` owns several `Datafield`s and also `Linkpanel`s.
FieldConverter.FieldDefOwner	/** A `DatafieldOwner` owns several `FieldDef`s and also `Linkpanel`s.
FieldWrapper	A `FieldWrapper` extends a `FieldDef` and adds the ability to read and set the field's string-representation ( `FieldWrapper.getStringValue()`/`FieldWrapper.setStringValue(String)`) and also the object-representation ( `FieldWrapper.getObject()`/ `FieldWrapper.setObject(Object)`).
FormDataBinder<T>	A `DataBinder` that uses a `Form` to bind its values to the target object.
MessageConstants
PathInfo	Default `Path`-implementation
PermissionOwner	This is a container for a set of `Permission`s, making it easier for a `PermissionProcessor` to check those.
Platform	Utility class providing platform-wide used constants.
RequestDataBinder<T>	A `DataBinder` that uses a `Request` to bind its values to the target object. This class is especially useful inside a `Webservice`, as shown below:
RequestUtil	Utility-class for mapping requests to `Site`s.
ScheduledJobResult	A `ScheduledJobResult` can be provided by a `ScheduledJob`.
Session	Utility-class providing constants used for accessing an `Session.Environment`-attribute with `Scope.SESSION`.
Session.Environment
SiteProperties	Utility-class providing constants for the names of a `Site`'s `Properties`.
SoapClient	A simple SOAP-client for JAXB-based webservices.
ValidationMessages	Utility class providing constants for the message-keys used in validation-annotations.
XPathProcessor	An `XPathProcessor` is used the create a `Document` from an `URL` or `InputStream` and then to extract `NodeList`s, `Node`s, `Element`s, `Attr`ibutes etc.

Enum Summary
Enum	Description
FileUpload.Unit	the unit to use for validating uploads by their size
ScheduledJobResult.ExecutionResult	simple enum reflecting the results a `ScheduledJob` execution can have.
Scope	Enum type defining the possible scopes of an `Environment`-attribute.
VHostMode	Enum type for the host-configuration of appNG.

Exception Summary
Exception	Description
ApplicationException	A `RuntimeException` to be used inside business logic.
BusinessException	An `Exception` to be used inside business logic.
InvalidConfigurationException	An `InvalidConfigurationException` is a checked exception thrown by the platform whenever something goes wrong during `Application`-execution. Some examples: a `Application` could not be found a `Resource` could not be found there was an error while reading a `Resource`, e.g.
ProcessingException	A checked exception that is thrown by `CallableAction` and `CallableDataSource`, to indicate an error occurred while assembling the `PageReference`.

Annotation Types Summary
Annotation Type	Description
FileUpload	Used to validate the size, filetype(s) and amount of a (`Collection`) of) `FormUpload`(s).
NotBlank	Checks whether the annotated element is not null and not blank by combining `@NotNull` and `@Size(min = 1)`.
