protected void doWriteTo(StreamOutput out)
                  throws java.io.IOException

Description copied from class: ScoreFunctionBuilder

Write the subclass's components into the stream.

Specified by:

doWriteTo in class ScoreFunctionBuilder<ScriptScoreFunctionBuilder>

Throws:

java.io.IOException

getScript

public Script getScript()

doXContent

public void doXContent(XContentBuilder builder,
                       ToXContent.Params params)
                throws java.io.IOException

Description copied from class: ScoreFunctionBuilder

Convert this subclass's data into XContent.

Specified by:

doXContent in class ScoreFunctionBuilder<ScriptScoreFunctionBuilder>

Throws:

java.io.IOException

getName

public java.lang.String getName()

Description copied from class: ScoreFunctionBuilder

The name of this score function.

Specified by:

getName in class ScoreFunctionBuilder<ScriptScoreFunctionBuilder>

doEquals

protected boolean doEquals(ScriptScoreFunctionBuilder functionBuilder)

Description copied from class: ScoreFunctionBuilder

Check that two instances of the same subclass of ScoreFunctionBuilder are equal. Implementers don't need to check any fields in ScoreFunctionBuilder, just fields that they define.

Specified by:

doEquals in class ScoreFunctionBuilder<ScriptScoreFunctionBuilder>

doHashCode

protected int doHashCode()

Description copied from class: ScoreFunctionBuilder

Hashcode for fields defined in this subclass of ScoreFunctionBuilder. Implementers should ignore fields defined in ScoreFunctionBuilder because they will already be in the hashCode.

Specified by:

doHashCode in class ScoreFunctionBuilder<ScriptScoreFunctionBuilder>

doToFunction

protected ScoreFunction doToFunction(QueryShardContext context)

Description copied from class: ScoreFunctionBuilder

Build the Lucene ScoreFunction for this builder. Implementers should ignore things defined in ScoreFunctionBuilder like weight as they will be handled by the function that calls this one.

Specified by:

doToFunction in class ScoreFunctionBuilder<ScriptScoreFunctionBuilder>

fromXContent

public static ScriptScoreFunctionBuilder fromXContent(XContentParser parser)
                                               throws java.io.IOException,
                                                      ParsingException

Throws:
