SFormatLevelDef

Description

The SFormatLevelDef component  defines SFormats that returns data for all objects that are related to the level immediately above it.

Implementation

• Add an SFormatLevelDef in a Hierachy inside the HierarchyService

• Define the SFormat used to search the children elements

• You can add more Sformats using the "+" button

• The matching child level elems will be displayed in the hierarchy (you might need to refresh the tree node)

Properties

• Query Context:The current location is one item that could be placed in the query context. The facet value is compared with the value of the context tag on a device or point at a lower level in the navigation tree. The query context can hold anything to be used in LevelDef queries. It is comparable to a hierarchy scoped variable. You could create multiple copies of such a hierarchy definition and then customize each copy with the query context of the specific hierarchy.

• Repeat Relation:
  

  • When true, the specified SFormat is evaluated until there are no further results. For example, if the SFormat “{origin.rel('out', 'n:child')}” is specified, the SFormat level def would be repeatedly evaluated until an Entity is reached that has no children

  • When false, the SFormat level def will only be evaluated once

• Caching Repeat Limit: The number of times this level def will be repeated, if possible, when the hierarchy is cached. This limit does not affect expansion of a non-cached hierarchy. This property is only relevant when the repeatRelation property is true.

• Sort: Determines the order in which results display

• Formats: SFormat values used to build the hierarchy.

Examples



used SFormats:

• {relations('in','b:isIn').filter('[{tag('b:level').lessThan(5)}]')}

• {relations('in','b:strSourceOf').filter('[{outRel('b:eqtSourceOf').isNull.not}]')}

• 'b:eqtSubSourceOf').filter('[{outRel('b:ptSourceOf').tag('b:definition').equals('pointType')}]')}

• {infoSource.relations('in', 'b:eqtSubSourceOf').relations('in', 'b:eqtSubSourceOf').filter('[{outRel('b:ptSourceOf').tag('b:definition').equals('pointType')}]')}

• {infoSource.relations('in', 'b:eqtSubSourceOf').relations('in', 'b:eqtSubSourceOf').relations('in', 'b:eqtSubSourceOf').filter('[{outRel('b:ptSourceOf').tag('b:definition').equals('pointType')}]')}
