FlowableAstFunctionCreatorAndDelegate, org.flowable.common.engine.api.delegate.FlowableFunctionDelegate, org.flowable.common.engine.api.delegate.FlowableMultiFunctionDelegate, org.flowable.common.engine.impl.el.FlowableAstFunctionCreator

public class ContentItemFunctionDelegate
extends Object
implements org.flowable.common.engine.api.delegate.FlowableMultiFunctionDelegate, FlowableAstFunctionCreatorAndDelegate

The following expressions are valid:

• content:getContentItem(<contentItemId>) - Get the content item with the given id
• content:getContentItemData(<contentItemId>) - Get the binary data of the content item as an InputStream
• content:getMetadataValues(<contentItemId>) - Get all metadata values for the content item with the given id
• content:getMetadataValue(<contentItemId>, <metadataName>) - Get a specific metadata value for the content item with the given id
• content:getRenditionItem(<renditionItemId>) - Get the rendition item with the given id
• content:getRenditionByType(<contentItemId>, <renditionType>) - Get the rendition item for the given content item and rendition type (e.g. pdf, thumbnail, structured)
• content:getRenditionItemData(<renditionItemId>) - Get the binary data of the rendition item as an InputStream
• content:getRenditionItemDataByType(<contentItemId>, <renditionType>) - Get the binary data of the rendition item matching the given type for the content item
