Method Details

toEvaluator

public static ExpressionEvaluator.Factory toEvaluator(FoldContext foldCtx,
 Expression exp,
 Layout layout)

toEvaluator

public static ExpressionEvaluator.Factory toEvaluator(FoldContext foldCtx,
 Expression exp,
 Layout layout,
 @Nullable
 AnalysisRegistry analysisRegistry)

Provides an ExpressionEvaluator factory to evaluate an expression that does not require shard contexts but may reference functions (e.g. TOP_SNIPPETS) that need the node-level AnalysisRegistry.

toEvaluator

public static ExpressionEvaluator.Factory toEvaluator(FoldContext foldCtx,
 Expression exp,
 Layout layout,
 IndexedByShardId<? extends EsPhysicalOperationProviders.ShardContext> shardContexts)

Provides an ExpressionEvaluator factory to evaluate an expression.

Parameters:

foldCtx - the fold context for folding expressions

exp - the expression to generate an evaluator for

layout - the mapping from attributes to channels

shardContexts - the shard contexts, needed to generate queries for expressions that couldn't be pushed down to Lucene
