Packages that use QueryNodeProcessor
org.apache.lucene.queryparser.flexible.core | Core classes of the flexible query parser framework.
org.apache.lucene.queryparser.flexible.core.processors | Interfaces and implementations used by query node processors
org.apache.lucene.queryparser.flexible.precedence.processors | Processors used by Precedence Query Parser

Uses of QueryNodeProcessor in org.apache.lucene.queryparser.flexible.core

Methods in org.apache.lucene.queryparser.flexible.core that return QueryNodeProcessor
`QueryNodeProcessor` | `QueryParserHelper.getQueryNodeProcessor()` Returns the processor object used to process the query node tree, it returns `null` if no processor is used.

Methods in org.apache.lucene.queryparser.flexible.core with parameters of type QueryNodeProcessor
`void` | `QueryParserHelper.setQueryNodeProcessor(QueryNodeProcessor processor)` Sets the processor that will be used to process the query node tree.

Constructors in org.apache.lucene.queryparser.flexible.core with parameters of type QueryNodeProcessor
`QueryParserHelper(QueryConfigHandler queryConfigHandler, SyntaxParser syntaxParser, QueryNodeProcessor processor, QueryBuilder builder)` Creates a query parser helper object using the specified configuration, text parser, processor and builder.

Uses of QueryNodeProcessor in org.apache.lucene.queryparser.flexible.core.processors

Classes in org.apache.lucene.queryparser.flexible.core.processors that implement QueryNodeProcessor
`class` | `NoChildOptimizationQueryNodeProcessor` A `NoChildOptimizationQueryNodeProcessor` removes every BooleanQueryNode, BoostQueryNode, TokenizedPhraseQueryNode or ModifierQueryNode that do not have a valid children.
`class` | `QueryNodeProcessorImpl` This is a default implementation for the `QueryNodeProcessor` interface, it's an abstract class, so it should be extended by classes that want to process a `QueryNode` tree.
`class` | `QueryNodeProcessorPipeline` A `QueryNodeProcessorPipeline` class should be used to build a query node processor pipeline.
`class` | `RemoveDeletedQueryNodesProcessor` A `QueryNodeProcessorPipeline` class removes every instance of `DeletedQueryNode` from a query node tree.

Methods in org.apache.lucene.queryparser.flexible.core.processors that return QueryNodeProcessor
`QueryNodeProcessor` | `QueryNodeProcessorPipeline.get(int index)`
`QueryNodeProcessor` | `QueryNodeProcessorPipeline.remove(int index)`
`QueryNodeProcessor` | `QueryNodeProcessorPipeline.set(int index, QueryNodeProcessor processor)`

Methods in org.apache.lucene.queryparser.flexible.core.processors that return types with arguments of type QueryNodeProcessor
`Iterator<QueryNodeProcessor>` | `QueryNodeProcessorPipeline.iterator()`
`ListIterator<QueryNodeProcessor>` | `QueryNodeProcessorPipeline.listIterator()`
`ListIterator<QueryNodeProcessor>` | `QueryNodeProcessorPipeline.listIterator(int index)`
`List<QueryNodeProcessor>` | `QueryNodeProcessorPipeline.subList(int fromIndex, int toIndex)`

Methods in org.apache.lucene.queryparser.flexible.core.processors with parameters of type QueryNodeProcessor
`void` | `QueryNodeProcessorPipeline.add(int index, QueryNodeProcessor processor)`
`boolean` | `QueryNodeProcessorPipeline.add(QueryNodeProcessor processor)`
`QueryNodeProcessor` | `QueryNodeProcessorPipeline.set(int index, QueryNodeProcessor processor)`

Method parameters in org.apache.lucene.queryparser.flexible.core.processors with type arguments of type QueryNodeProcessor
`boolean` | `QueryNodeProcessorPipeline.addAll(Collection<? extends QueryNodeProcessor> c)`
`boolean` | `QueryNodeProcessorPipeline.addAll(int index, Collection<? extends QueryNodeProcessor> c)`

Uses of QueryNodeProcessor in org.apache.lucene.queryparser.flexible.precedence.processors

Classes in org.apache.lucene.queryparser.flexible.precedence.processors that implement QueryNodeProcessor
`class` | `BooleanModifiersQueryNodeProcessor` This processor is used to apply the correct `ModifierQueryNode` to `BooleanQueryNode`s children.
`class` | `PrecedenceQueryNodeProcessorPipeline` This processor pipeline extends `StandardQueryNodeProcessorPipeline` and enables boolean precedence on it.

Uses of QueryNodeProcessor in org.apache.lucene.queryparser.flexible.standard.processors

Classes in org.apache.lucene.queryparser.flexible.standard.processors that implement QueryNodeProcessor
`class` | `AllowLeadingWildcardProcessor` This processor verifies if `StandardQueryConfigHandler.ConfigurationKeys.ALLOW_LEADING_WILDCARD` is defined in the `QueryConfigHandler`.
`class` | `AnalyzerQueryNodeProcessor` This processor verifies if `StandardQueryConfigHandler.ConfigurationKeys.ANALYZER` is defined in the `QueryConfigHandler`.
`class` | `BooleanQuery2ModifierNodeProcessor` This processor is used to apply the correct `ModifierQueryNode` to `BooleanQueryNode`s children.
`class` | `BooleanSingleChildOptimizationQueryNodeProcessor` This processor removes every `BooleanQueryNode` that contains only one child and returns this child.
`class` | `BoostQueryNodeProcessor` This processor iterates the query node tree looking for every `FieldableNode` that has `StandardQueryConfigHandler.ConfigurationKeys.BOOST` in its config.
`class` | `DefaultPhraseSlopQueryNodeProcessor` This processor verifies if `StandardQueryConfigHandler.ConfigurationKeys.PHRASE_SLOP` is defined in the `QueryConfigHandler`.
`class` | `FuzzyQueryNodeProcessor` This processor iterates the query node tree looking for every `FuzzyQueryNode`, when this kind of node is found, it checks on the query configuration for `StandardQueryConfigHandler.ConfigurationKeys.FUZZY_CONFIG`, gets the fuzzy prefix length and default similarity from it and set to the fuzzy node.
`class` | `GroupQueryNodeProcessor` Deprecated. use `BooleanQuery2ModifierNodeProcessor` instead
`class` | `LowercaseExpandedTermsQueryNodeProcessor` This processor verifies if `StandardQueryConfigHandler.ConfigurationKeys.LOWERCASE_EXPANDED_TERMS` is defined in the `QueryConfigHandler`.
`class` | `MatchAllDocsQueryNodeProcessor` This processor converts every `WildcardQueryNode` that is "*:*" to `MatchAllDocsQueryNode`.
`class` | `MultiFieldQueryNodeProcessor` This processor is used to expand terms so the query looks for the same term in different fields.
`class` | `MultiTermRewriteMethodProcessor` This processor instates the default `MultiTermQuery.RewriteMethod`, `MultiTermQuery.CONSTANT_SCORE_AUTO_REWRITE_DEFAULT`, for multi-term query nodes.
`class` | `NumericQueryNodeProcessor` This processor is used to convert `FieldQueryNode`s to `NumericRangeQueryNode`s.
`class` | `NumericRangeQueryNodeProcessor` This processor is used to convert `TermRangeQueryNode`s to `NumericRangeQueryNode`s.
`class` | `OpenRangeQueryNodeProcessor` Processes `TermRangeQuery`s with open ranges.
`class` | `PhraseSlopQueryNodeProcessor` This processor removes invalid `SlopQueryNode` objects in the query node tree.
`class` | `RemoveEmptyNonLeafQueryNodeProcessor` This processor removes every `QueryNode` that is not a leaf and has not children.
`class` | `StandardQueryNodeProcessorPipeline` This pipeline has all the processors needed to process a query node tree, generated by `StandardSyntaxParser`, already assembled.
`class` | `TermRangeQueryNodeProcessor` This processors process `TermRangeQueryNode`s.
`class` | `WildcardQueryNodeProcessor` The `StandardSyntaxParser` creates `PrefixWildcardQueryNode` nodes which have values containing the prefixed wildcard.
