Package freemarker.template

The fundamental, most commonly used API-s of FreeMarker; start with Configuration (see also the Getting Started in the Manual.)

Interface Summary

Interface	Description
AdapterTemplateModel	A TemplateModel that can be unwrapped and then it considers a provided desired (hint) class.
AttemptExceptionReporter	Used for the attempt_exception_reported configuration setting.
ObjectWrapper	Maps Java objects to the type-system of FreeMarker Template Language (see the TemplateModel interfaces).
ObjectWrapperAndUnwrapper	Experimental - subject to change: Adds functionality to ObjectWrapper that creates a plain Java object from a TemplateModel.
TemplateBooleanModel	"boolean" template language data type; same as in Java; either true or false.
TemplateCollectionModel	"collection" template language data type: a collection of values that can be enumerated, but can't be or not meant to be accessed by index or key, nor the number of elements in it is known.
TemplateCollectionModelEx	"collection" template language data type: Adds size/emptiness querybility to TemplateCollectionModel.
TemplateDateModel	"date", "time" and "date-time" template language data types: corresponds to Date.
TemplateDirectiveBody	Represents the nested content of a directive (TemplateDirectiveModel) invocation.
TemplateDirectiveModel	"directive" template language data type: used as user-defined directives (much like macros) in templates.
TemplateExceptionHandler	Used for the template_exception_handler configuration setting.
TemplateHashModel	"hash" template language data type: an object that contains other objects accessible through string keys (sub-variable names).
TemplateHashModelEx	"extended hash" template language data type; extends TemplateHashModel by allowing iterating through its keys and values.
TemplateHashModelEx2	Adds key-value pair listing capability to TemplateHashModelEx.
TemplateHashModelEx2.KeyValuePair	A key-value pair in a hash; used for TemplateHashModelEx2.KeyValuePairIterator.
TemplateHashModelEx2.KeyValuePairIterator	Iterates over the key-value pairs in a hash.
TemplateMethodModel	Deprecated. Use TemplateMethodModelEx instead.
TemplateMethodModelEx	"extended method" template language data type: Objects that act like functions.
TemplateModel	The common super-interface of the interfaces that stand for the FreeMarker Template Language (FTL) data types.
TemplateModelAdapter	Implemented by classes that serve as adapters for template model objects in some other object model.
TemplateModelIterator	Used to iterate over a set of template models once; usually returned from TemplateCollectionModel.iterator().
TemplateModelWithAPISupport	A TemplateModel on which the ?api operation can be applied.
TemplateNodeModel	"node" template language data type: an object that is a node in a tree.
TemplateNodeModelEx	A TemplateNodeModel that supports navigating to the previous and next sibling nodes.
TemplateNumberModel	"number" template language data type; an object that stores a number.
TemplateScalarModel	"string" template language data-type; like in Java, an unmodifiable UNICODE character sequence.
TemplateSequenceModel	"sequence" template language data type; an object that contains other objects accessible through an integer 0-based index.
TemplateTransformModel	"transform" template language data type: user-defined directives (much like macros) specialized on filtering output; you should rather use the newer TemplateDirectiveModel instead.
TransformControl	An interface that can be implemented by writers returned from TemplateTransformModel.getWriter(java.io.Writer, java.util.Map).

Class Summary

Class	Description
Configuration	The main entry point into the FreeMarker API; encapsulates the configuration settings of FreeMarker, also serves as a central template-loading and caching service.
DefaultArrayAdapter	Adapts an array of a non-primitive elements to the corresponding TemplateModel interface(s), most importantly to TemplateHashModelEx.
DefaultEnumerationAdapter	Adapts an Enumeration to the corresponding TemplateModel interface(s), most importantly to TemplateCollectionModel.
DefaultIterableAdapter	Adapts an Iterable to the corresponding TemplateModel interface(s), most importantly to TemplateCollectionModel.
DefaultIteratorAdapter	Adapts an Iterator to the corresponding TemplateModel interface(s), most importantly to TemplateCollectionModel.
DefaultListAdapter	Adapts a List to the corresponding TemplateModel interface(s), most importantly to TemplateSequenceModel.
DefaultMapAdapter	Adapts a Map to the corresponding TemplateModel interface(s), most importantly to TemplateHashModelEx.
DefaultNonListCollectionAdapter	Adapts a non-List Java Collection to the corresponding TemplateModel interface(s), most importantly to TemplateCollectionModelEx.
DefaultObjectWrapper	The default implementation of the ObjectWrapper interface.
DefaultObjectWrapperBuilder	Gets/creates a DefaultObjectWrapper singleton instance that's already configured as specified in the properties of this object; this is recommended over using the DefaultObjectWrapper constructors.
DefaultObjectWrapperConfiguration	Holds DefaultObjectWrapper configuration settings and defines their defaults.
LocalizedString	An abstract base class for scalars that vary by locale.
MapKeyValuePairIterator	Implementation of TemplateHashModelEx2.KeyValuePairIterator for a TemplateHashModelEx2 that wraps or otherwise uses a Map internally.
ResourceBundleLocalizedString	A concrete implementation of LocalizedString that gets a localized string from a ResourceBundle
SimpleCollection	A simple implementation of TemplateCollectionModel.
SimpleDate	A simple implementation of the TemplateDateModel interface.
SimpleHash	A simple implementation of the TemplateHashModelEx interface, using its own underlying Map or SortedMap for storing the hash entries.
SimpleList	Deprecated. Use SimpleSequence instead.
SimpleNumber	A simple implementation of the TemplateNumberModel interface.
SimpleObjectWrapper	A restricted object wrapper that will not expose arbitrary object, just those that directly correspond to the TemplateModel sub-interfaces (String, Map and such).
SimpleScalar	A simple implementation of the TemplateScalarModel interface, using a String.
SimpleSequence	A simple implementation of the TemplateSequenceModel interface, using its own underlying List for storing the list items.
Template	Stores an already parsed template, ready to be processed (rendered) for unlimited times, possibly from multiple threads.
TemplateModelListSequence	A sequence that wraps a List of TemplateModel-s.
Version	Represents a version number plus the further qualifiers and build info.
WrappingTemplateModel	Convenience base-class for containers that wrap their contained arbitrary Java objects into TemplateModel instances.

Exception Summary

Exception	Description
MalformedTemplateNameException	Indicates that the template name given was malformed according the TemplateNameFormat in use.
Template.WrongEncodingException	Thrown by the Template constructors that specify a non-null encoding whoch doesn't match the encoding specified in the #ftl header of the template.
TemplateException	Runtime exception in a template (as opposed to a parsing-time exception: ParseException).
TemplateModelException	ObjectWrapper-s may throw this when wrapping/unwrapping fails, or TemplateModel methods throw this if the requested data can't be retrieved.
TemplateNotFoundException	Thrown when Configuration.getTemplate(String) (or similar) doesn't find a template.
