PrefixWildcardQueryNode

class PrefixWildcardQueryNode(field: CharSequence?, text: CharSequence?, begin: Int, end: Int) : WildcardQueryNode

A PrefixWildcardQueryNode represents wildcardquery that matches abc* or *. This does not apply to phrases, this is a special case on the original lucene parser. TODO: refactor the code to remove this special case from the parser. and probably do it on a Processor

override fun add(children: List<QueryNode>)

override fun add(child: QueryNode)

clone

open override fun clone(): QueryNode

cloneTree

open override fun cloneTree(): PrefixWildcardQueryNode

Recursive clone the QueryNode tree The tags are not copied to the new tree when you call the cloneTree() method

containsTag

open override fun containsTag(tagName: String): Boolean

verify if a node contains a tag

getFieldAsString

fun getFieldAsString(): String?

returns null if the field was not specified in the query string

getTag

open override fun getTag(tagName: String): Any?

Returns object stored under that tag name

getTextAsString

fun getTextAsString(): String?

removeChildren

open override fun removeChildren(childNode: QueryNode)

Remove a child node

removeFromParent

open override fun removeFromParent()

Removes this query node from its parent.

set
