getWriteableName in interface NamedWriteable

writeTo

public final void writeTo(StreamOutput out)
                   throws IOException

Specified by:

writeTo in interface Writeable

Throws:

IOException

resolveParams

protected Expression.TypeResolution resolveParams()

Description copied from class: FullTextFunction

Resolves the type for the function parameters, as part of the type resolution for the function

Overrides:

resolveParams in class SingleFieldFullTextFunction

Returns:

type resolution for the function parameters

getFieldDataTypes

protected Set<DataType> getFieldDataTypes()

Description copied from class: SingleFieldFullTextFunction

Returns the set of allowed data types for the field parameter. Each subclass defines which field types it supports.

Specified by:

getFieldDataTypes in class SingleFieldFullTextFunction

getQueryDataTypes

protected Set<DataType> getQueryDataTypes()

Description copied from class: SingleFieldFullTextFunction

Returns the set of allowed data types for the query parameter. Each subclass defines which query types it supports.

Specified by:

getQueryDataTypes in class SingleFieldFullTextFunction

getAllowedOptions

protected Map<String,DataType> getAllowedOptions()

Description copied from class: SingleFieldFullTextFunction

Returns the allowed options map for this function. Keys are option names, values are the expected data types.

Specified by:

getAllowedOptions in class SingleFieldFullTextFunction

info

protected NodeInfo<? extends Expression> info()

Specified by:

info in class Node<Expression>

replaceChildren

public Expression replaceChildren(List<Expression> newChildren)

Specified by:

replaceChildren in class Node<Expression>

replaceQueryBuilder

public Expression replaceQueryBuilder(QueryBuilder queryBuilder)

Description copied from interface: RewriteableAware

Replaces the current query builder with a rewritten iteration. This happens multiple times through the rewrite phase until the final iteration of the query builder is stored.

Specified by:

replaceQueryBuilder in interface RewriteableAware

Parameters:

queryBuilder - QueryBuilder

Returns:

Expression defining the active QueryBuilder

translate

protected Query translate(LucenePushdownPredicates pushdownPredicates,
 TranslatorHandler handler)

Specified by:

translate in class FullTextFunction
