Class ListDirective

java.lang.Object

ch.tocco.nice2.templating.impl.freemarker.directives.ListDirective

All Implemented Interfaces:

Nice2TemplateDirective, freemarker.template.TemplateDirectiveModel, freemarker.template.TemplateModel

public class ListDirective
extends Object
implements Nice2TemplateDirective

A directive that iterates over a TemplateSequenceModel. It contains special handling for EntityListSequenceModel: If the EntityList contains more than DEFAULT_BATCH_SIZE entities, a MemoryEfficientLazyEntityList is used that creates a new Context for each batch. Note: The input should to be a type of EntityList that can provide the keys without loading all entities, like a LazyEntityList (which is for example provided by GroupByMethod, OrderByMethod or QueryDirective). All other TemplateSequenceModel are handled normally. The following parameters are available: - 'source': The TemplateSequenceModel that should be iterated (required) - 'var': The name of the loop variable (default: 'entity') - 'batchSize': Number of entities after which a new context is created (default: 50, applies to EntityListSequenceModel only)
