Properties

Optional descendantCountProperty

descendantCountProperty?: string

Property holding the number of descendants of a node The descendant count of a node is the number of its descendants in the hierarchy structure of the result considering only those nodes matching any specified $filter and $search. A property holding descendant counts has an integer data type.

Optional drillStateProperty

drillStateProperty?: string

Property holding the drill state of a node The drill state is indicated by one of the following string values: collapsed, expanded, leaf. For an expanded node, its children are included in the result collection. For a collapsed node, the children are included in the entity set, but they are not part of the result collection. Retrieving them requires a relaxed filter expression or a separate request filtering on the parent node ID with the ID of the collapsed node. A leaf does not have any child in the entity set.

Optional externalKeyProperty

externalKeyProperty?: string

Optional id

id?: string

Optional labelProperty

labelProperty?: string

Optional levelProperty

levelProperty?: string

Optional memberTypeProperty

memberTypeProperty?: string

parentNodeProperty

parentNodeProperty: string

Optional preorderRankProperty

preorderRankProperty?: string

Property holding the preorder rank of a node The preorder rank of a node expresses its position in the sequence of nodes created from preorder traversal of the hierarchy structure after evaluating the $filter expression in the request excluding any conditions on key properties. The first node in preorder traversal has rank 0.

Optional siblingRankProperty

siblingRankProperty?: string

Property holding the sibling rank of a node The sibling rank of a node is the index of the node in the sequence of all nodes with the same parent created by preorder traversal of the hierarchy structure after evaluating the $filter expression in the request excluding any conditions on key properties. The first sibling is at position 0.
