Link Functions

Links can be inserted into dashboard tables using the link function. All link types described in Internal Links can be added to dashboard tables using the link function. In addition to the link function there are convenience functions such as annotation, dashboard, data and stepping that make it easier to supply the required link parameters.

Annotation

DEPRECATED - replaced by fully integrated Stroom annotation functionality and createAnnotation

A helper function to make forming links to annotations easier than using Link. The Annotation function allows you to create a link to open the Annotation editor, either to view an existing annotation or to begin creating one with pre-populated values.

annotation(text, annotationId)
annotation(text, annotationId, [streamId, eventId, title, subject, status, assignedTo, comment])

If you provide just the text and an annotationId then it will produce a link that opens an existing annotation with the supplied ID in the Annotation Edit dialog.

Example

annotation('Open annotation', ${annotation:Id})
> [Open annotation](?annotationId=1234){annotation}
annotation('Create annotation', '', ${StreamId}, ${EventId})
> [Create annotation](?annotationId=&streamId=1234&eventId=45){annotation}
annotation('Escalate', '', ${StreamId}, ${EventId}, 'Escalation', 'Triage required')
> [Escalate](?annotationId=&streamId=1234&eventId=45&title=Escalation&subject=Triage%20required){annotation}

If you don’t supply an annotationId then the link will open the Annotation Edit dialog pre-populated with the optional arguments so that an annotation can be created. If the annotationId is not provided then you must provide a streamId and an eventId. If you don’t need to pre-populate a value then you can use '' or null() instead.

Example

annotation('Create suspect event annotation', null(), 123, 456, 'Suspect Event', null(), 'assigned', 'jbloggs')
> [Create suspect event annotation](?streamId=123&eventId=456&title=Suspect%20Event&assignedTo=jbloggs){annotation}

CreateAnnotation

Since annotation editing is now performed as a primary Stroom feature via a button and context menu on dashboard and query tables we no longer need to create or edit annotations via a hyperlink. There are some remaining use cases where users want to create and initialise some annotation values based on some table row content. The createAnnotation function can be used for this purpose and shows a hyperlink that will open the annotation edit screen pre-populated with the supplied values ready to create a new annotation.

The function takes the arguments:

createAnnotation(text, title, subject, status, assignedTo, comment, eventIdList)

Example:

createAnnotation('Create Annotation', 'My Annotation Title', ${SubjectField}, 'New', 'UserA', 'Look at this thing', '123:2,123444:3')

Dashboard

A helper function to make forming links to dashboards easier than using Link.

dashboard(text, uuid)
dashboard(text, uuid, params)

Example

dashboard('Click Here','e177cf16-da6c-4c7d-a19c-09a201f5a2da')
> [Click Here](?uuid=e177cf16-da6c-4c7d-a19c-09a201f5a2da){dashboard}
dashboard('Click Here','e177cf16-da6c-4c7d-a19c-09a201f5a2da', 'userId=user1')
> [Click Here](?uuid=e177cf16-da6c-4c7d-a19c-09a201f5a2da&params=userId%3Duser1){dashboard}

Data

A helper function to make forming links to data easier than using Link.

data(text, id, partNo, [recordNo, lineFrom, colFrom, lineTo, colTo, viewType, displayType])

Example

data('Quick View', ${StreamId}, 1)
> [Quick View]?id=1234&&partNo=1)

Example of non-segmented raw data section, viewed un-formatted in a stroom tab:

data('View Raw', ${StreamId}, ${partNo}, null(), 5, 1, 5, 342, 'source', 'tab')

Example of a single record (event) from a segmented stream, viewed formatted in a popup dialog:

data('View Cooked', ${StreamId}, 1, ${eventId})

Example of a single record (event) from a segmented stream, viewed formatted in a stroom tab:

data('View Cooked', ${StreamId}, 1, ${eventId}, null(), null(), null(), null(), 'preview', 'tab')

Example of a single event metadata record from a segmented stream, viewed in a popup dialog:

data('View Cooked', ${StreamId}, 1, ${eventId}, null(), null(), null(), null(), 'info')

Link

Create a string that represents a hyperlink for display in a dashboard table.

link(url)
link(text, url)
link(text, url, type)

Example

link('https://www.somehost.com/somepath')
> [https://www.somehost.com/somepath](https://www.somehost.com/somepath)
link('Click Here','https://www.somehost.com/somepath')
> [Click Here](https://www.somehost.com/somepath)
link('Click Here','https://www.somehost.com/somepath', 'dialog')
> [Click Here](https://www.somehost.com/somepath){dialog}
link('Click Here','https://www.somehost.com/somepath', 'dialog|Dialog Title')
> [Click Here](https://www.somehost.com/somepath){dialog|Dialog Title}

Stepping

Open the Stepping tab for the requested data source.

stepping(text, id)
stepping(text, id, partNo)
stepping(text, id, partNo, recordNo)

Example

stepping('Click here to step',${StreamId})
> [Click here to step](?id=1)
