Send

Description

Send worker data, event, and/or file through a channel.

Conceptually, this is like performing a Set at the other end of the channel, though whether it is actually a Set or another action depends on the process at the other partner.

The Send could be achieved using a Call, but Send is simpler for sending worker data and events.

The send is configured with a merge of config properties and properties in the "data" request parameter, request parameter overriding the configuration properties.

The configuration parameters/request parameters available for Set when show is false are passed through the channel, together with an action property. The following properties are also available.

remoteAction

The action which should be used at the remote end. This is used to create an action parameter in the data, overwriting any existing action parameter.

This is required if the set has been called remotely, where the action parameter will already be set.

Can be set in config or the the data parameter.

This is mandatory.

role

The role reference for the channel to which the data should be sent.

Can be set in config or the the data parameter.

This is mandatory.

dataReferenceFrom

Reference from which data should be read. This can be used to pass data from a data node, rather than from a request parameter. Use this to send data from one party to another.

Can be set in config or the the data parameter.

dataReferenceFrom is ignored if the data property is set.

dataPropertyFrom

Extract just one property from the data. This can be used to extract just data from a form, for example.

Can be set in config or the the data parameter.

remote

This has the same meaning as remote in set. It applies to the send itself, not the remotely-requested send. Setting this allow a channel partner to request that data is sent to them, i.e. allows a channel partner to retrieve data.

Can only be set in config.

permit

Same usage as set step, indicates which properties can be passed in the parameters. As well as the parameters for set, this supports remoteAction, channel, dataReferenceFrom and dataPropertyFrom.

Can only be set in config.

Send supports runtime placeholders.
