PropertyDefinedNode

Kotlin |Java

@ExperimentalAppSearchApi
public final class PropertyDefinedNode implements FunctionNode

FunctionNode representing the `propertyDefined` query function.

The `propertyDefined` query function will return all documents of types that define the given property. This will include documents that do not have the property itself, so long as that property is a part of the document's schema.

If you need to restrict to documents that have >=1 value(s) populated for that property, see HasPropertyNode.
