public class InvokeAssembler
extends DynamoServlet

This droplet acts as an entry point into the Assembler API. The droplet is used to make a request for content from an Endeca application. The droplet has multiple parameters.

Input Parameters

includePath: A path used to return an Endeca 'page'. The path is passed into a ContentInclude ContentItem. An example of an include path is "/browse", used to return a browse page defined in Experience Manager. No other parameters should be used in conjunction with this parameter.

contentCollection: A path used to return an Endeca 'slot' in Experience Manager. The path is passed into a ContentSlotConfig ContentItem. An example of a content collection is "/shared/SearchBoxAutoSuggestContent", used to return a content collection called SearchBoxAutoSuggestContent. This parameter may be used in conjunction with ruleLimit.

contentItemType: A string used to indicate that the handler for a particular content item type should be called directly. For example "ResultsList" will cause the Assembler to try and determine the handler for cartridges of type ResultsList and invoke the handler.

ruleLimit: Used in conjunction with the contentCollection parameter. Indicates how many rules can fire for this particular slot.

Open Parameters

output: Rendered when the Assembler returns content.

error: Rendered when an error occurred. Log files can be used to determine the nature of the error.

Output Parameters

contentItem: The content (ContentItem) assembled by the invocation of the Assembler.

This droplet can be called from a page like so:

Method Detail

getAssemblerTools

public AssemblerTools getAssemblerTools()

Returns:

The assembler tools class

setAssemblerTools

public void setAssemblerTools(AssemblerTools pAssemblerTools)

Set a new assembler tools class

Parameters:

pAssemblerTools -

service

public void service(DynamoHttpServletRequest pRequest,
                    DynamoHttpServletResponse pResponse)
             throws javax.servlet.ServletException,
                    java.io.IOException

Invokes the Assembler and assembles the content specified by the "includePath" input parameter or the "contentCollection" input parameter. The assembled content will be available in the "contentItem" output parameter rendered inside the "output" open parameter. If no content is assembled the "empty" open parameter is rendered. If an error occurs the "error" open parameter is rendered.

Overrides:

service in class DynamoServlet

Parameters:

pRequest - the request to be processed
