Uses of Helper in org.trimou.handlebars

Classes in org.trimou.handlebars that implement Helper

Modifier and Type	Class and Description
class	AbstractHelper An abstract helper that holds a reference to the TextSupport.
class	AlternativesHelper Selects one object from the set of alternatives (usually helper parameters) and: for variable - renders its Object.toString() value or if no such object exists renders the output of MissingValueHandler.handle(org.trimou.engine.MustacheTagInfo) for section - pushes the object on the context stack or does nothing if no such object exists If no AlternativesHelper.Selector instance is declared the default behavior is: take the first parameter matching the condition (by default not null or not empty for an instance of String).
class	AsyncHelper A simple helper whose content is rendered asynchronously.
class	BasicSectionHelper
class	BasicValueHelper
class	BasicHelper Basic validating helper.
class	CacheHelper Allows to cache template fragments in memory.
class	EachHelper Iterates over the params or the object at the top of the context stack.
class	EmbedHelper Embed the template source.
class	EqualsHelper Renders a block if the first param does/doesn't equal to the second param (by means of Object.equals(Object)).
class	EvalHelper Allows to build the key dynamically and evaluate it afterwards.
class	FormatHelper A simple printf-style format helper.
class	ChooseHelper This helper works similarly as the JSP c:choose tag.
static class	ChooseHelper.OtherwiseHelper
static class	ChooseHelper.WhenHelper The first param is the test condition.
class	IfHelper Renders a block if the param is not "falsy".
class	IncludeHelper Works similarly as partial tag except the name of the template to include may be obtained dynamically.
class	InvokeHelper Invokes public methods with parameters via reflection.
class	IsHelper Renders the second param if the first param is not falsy, or (optionally, i.e. if set) the third param.
class	JoinHelper This helper takes all the objects specified as the parameters and joins the Object.toString() values together with the specified delimiter (optional).
class	LogHelper A simple log helper.
class	NullCheckHelper Renders a block if the param is/isn't null.
class	NumberIsEvenHelper {{isEven iterIndex "evenRow"}} {{isEven iterIndex "evenRow" "oddRow"}} {{#isEven iterIndex}} ...
class	NumberIsOddHelper {{isOdd iterIndex "oddRow"}} {{isOdd iterIndex "oddRow" "evenRow"}} {{#isOdd iterIndex}} ...
class	NumberMatchingHelper An abstract helper for matching Number values.
class	NumericExpressionHelper A simple numeric expression helper.
class	RepeatHelper Allows to repeat the section multiple times: {{#repeat times=3}} Hello three times!
class	SetHelper Works similarly as WithHelper except the current HelperDefinition.getHash() map is pushed on the context stack.
class	SwitchHelper This helper works similarly as the Java switch statement.
static class	SwitchHelper.CaseHelper The first param is the matching value.
static class	SwitchHelper.DefaultHelper
class	TagHelper This helper allows to easily render tags which make use of the same delimiters as Trimou does (i.e. would be normally parsed as mustache tags).
class	UnlessHelper Renders a block if the param is "falsy".
class	WithHelper Nested context.
