Examples with RangeMapFloatFunction org.apache.lucene.queries.function.valuesource.RangeMapFloatFunction used on opensource projects

Example 1 with RangeMapFloatFunction

use of org.apache.lucene.queries.function.valuesource.RangeMapFloatFunction in project lucene-solr by apache.

the class TestValueSources method testRangeMap.

public void testRangeMap() throws Exception {
    assertHits(new FunctionQuery(new RangeMapFloatFunction(new FloatFieldSource("float"), 5, 6, 1, 0f)), new float[] { 1f, 0f });
    assertHits(new FunctionQuery(new RangeMapFloatFunction(new FloatFieldSource("float"), 5, 6, new SumFloatFunction(new ValueSource[] { new ConstValueSource(1f), new ConstValueSource(2f) }), new ConstValueSource(11f))), new float[] { 3f, 11f });
// TODO: what *should* the rules be for exist() ?
// ((source exists && source in range && target exists) OR (source not in range && default exists)) ?
}

Example 2 with RangeMapFloatFunction

use of org.apache.lucene.queries.function.valuesource.RangeMapFloatFunction in project lucene-solr by apache.

the class TestFunctionQueryExplanations method testMapFunction.

public void testMapFunction() throws Exception {
    ValueSource rff = new RangeMapFloatFunction(new ConstValueSource(3), 0, 1, 2, new Float(4));
    Query q = new FunctionQuery(rff);
    qtest(q, new int[] { 0, 1, 2, 3 });
    assertEquals("map(const(3.0),0.0,1.0,const(2.0),const(4.0))", rff.description());
    assertEquals("map(const(3.0),min=0.0,max=1.0,target=const(2.0),defaultVal=const(4.0))", rff.getValues(null, null).toString(123));
    // DefaultValue is null -> defaults to source value
    rff = new RangeMapFloatFunction(new ConstValueSource(3), 0, 1, 2, null);
    assertEquals("map(const(3.0),0.0,1.0,const(2.0),null)", rff.description());
    assertEquals("map(const(3.0),min=0.0,max=1.0,target=const(2.0),defaultVal=null)", rff.getValues(null, null).toString(123));
