FunctionNode

Kotlin |Java

@ExperimentalAppSearchApi
interface FunctionNode : Node

Known direct subclasses

`GetSearchStringParameterNode`	`FunctionNode` that represents the getSearchStringParameter function.
`HasPropertyNode`	`FunctionNode` representing the `hasProperty` query function.
`PropertyDefinedNode`	`FunctionNode` representing the `propertyDefined` query function.
`SearchNode`	`FunctionNode` that represents the search function.
`SemanticSearchNode`	`FunctionNode` that represents the semanticSearch function.

Node that represents a function.

Every function node will have a function name and some arguments represented as fields on the class extending FunctionNode.

FunctionNode should be implemented by a node that implements a specific function.
