AbstractRangeQueryNode

open class AbstractRangeQueryNode<T : FieldValuePairQueryNode<*>> : QueryNodeImpl, RangeQueryNode<FieldValuePairQueryNode<*>>

This class should be extended by nodes intending to represent range queries.

Type Parameters

T

the type of the range query bounds (lower and upper)

Inheritors

PointRangeQueryNode

TermRangeQueryNode

Properties

override val children: MutableList<QueryNode>?

open override var field: CharSequence?

Returns the field associated with this node.

override val isLeaf: Boolean

verify if a node is a Leaf node

isLowerInclusive

open override val isLowerInclusive: Boolean

Returns whether the lower bound is inclusive or exclusive.

isUpperInclusive

open override val isUpperInclusive: Boolean

Returns whether the upper bound is inclusive or exclusive.

open override val lowerBound: T

Returns the lower bound node.

override val parent: QueryNode?

override val tagMap: Map<String, Any>

Returns a map containing all tags attached to this query node.

open override val upperBound: T

Returns the upper bound node.

Functions

override fun add(children: List<QueryNode>)

override fun add(child: QueryNode)

open override fun clone(): QueryNode

open override fun cloneTree(): QueryNode

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

open override fun containsTag(tagName: String): Boolean

verify if a node contains a tag

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

Returns object stored under that tag name

open override fun removeChildren(childNode: QueryNode)

Remove a child node

removeFromParent

open override fun removeFromParent()

Removes this query node from its parent.

override fun set(children: List<QueryNode>)

fun setBounds(lower: T?, upper: T?, lowerInclusive: Boolean, upperInclusive: Boolean)

Sets the lower and upper bounds.

open override fun setTag(tagName: String, value: Any)

Associate the specified value with the specified tagName. If the tagName already exists, the old value is replaced. The tagName and value cannot be null. tagName will be converted to lowercase.

open override fun toQueryString(escapeSyntaxParser: EscapeQuerySyntax): CharSequence

convert to a query string understood by the query parser

open override fun toString(): String

Every implementation of this class should return pseudo xml like this:

open override fun unsetTag(tagName: String)

Unset a tag. tagName will be converted to lowercase.
