@ExperimentalAppSearchApi
class PropertyDefinedNode : 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.

Summary

Public constructors
`PropertyDefinedNode(propertyPath: PropertyPath)` Constructor for a `PropertyDefinedNode` representing the query function `propertyDefined` that takes in a `PropertyPath`.

Public functions
`Boolean`	`equals(o: Any!)`
`String`	`getFunctionName()` Returns the name of the function represented by `PropertyDefinedNode`.
`PropertyPath`	`getPropertyPath()` Returns the `PropertyPath` representing the property being checked for in the document.
`Int`	`hashCode()`
`Unit`	`setPropertyPath(property: PropertyPath)` Sets the property being checked for in the document, as represented by `PropertyDefinedNode`.
`String`	`toString()` Get the string representation of `PropertyDefinedNode`.
