Functions

override fun add(children: List<QueryNode>)

override fun add(child: QueryNode)

open override fun clone(): QueryNode

open override fun cloneTree(): QueryNode

getFieldAsString

fun getFieldAsString(): String?

Returns object stored under that tag name

open override fun removeChildren(childNode: QueryNode)

Remove a child node

removeFromParent
