class NodeQuery(definition: NodeDefinition, val options: NodeQueryOptions, entries: List<NodeQueryEntry<*>>) : QueryBase<NodeQuery>

Defines a query which fetches Nodes of type definition

Parameters

definition

defines which type of Node is fetched

private val entryLookup: Map<String, List<NodeQueryEntry<*>>>

Lookup to get an entry efficiently by resultKeyPath Each group contains all entries under a specific resultKey Necessary as resultKey may not be unique, as only NodeQueryEntry.resultKeyPath with any element of NodeQueryEntry.onlyOnTypes must be unique

Functions

fun affectsNode(node: Node): Boolean

Checks if any part of this node query affects the given node

open override fun copyWithEntries(entries: List<NodeQueryEntry<*>>): NodeQuery

Copies this query and sets the entries to the given entries

Link copied to clipboard
fun getEntry(resultKey: String, nodeDefinitionProvider: () -> NodeDefinition): NodeQueryEntry<*>

Gets an entry by NodeQueryEntry.resultKeyPath. As multiple subqueries can use the same resultKeyPath if they use different NodeQueryEntry.onlyOnTypes, a list of NodeDefinitions may be necessary to get the correct subquery. This is provided as provider as evaluation is expensive and only necessary in few cases
