Example 1 with ReadFieldsFirst

use of org.apache.flink.api.java.functions.FunctionAnnotation.ReadFieldsFirst in project flink by apache.

the class SemanticPropUtil method getSemanticPropsDual.

public static DualInputSemanticProperties getSemanticPropsDual(Set<Annotation> set, TypeInformation<?> inType1, TypeInformation<?> inType2, TypeInformation<?> outType) {
    if (set == null) {
        return null;

Example 2 with ReadFieldsFirst

use of org.apache.flink.api.java.functions.FunctionAnnotation.ReadFieldsFirst in project flink by apache.

the class SemanticPropUtil method getSemanticPropsSingle.

    if (set == null) {
        return null;
    }
    Iterator<Annotation> it = set.iterator();

        }
    }
    if (forwarded != null || nonForwarded != null || read != null) {
        SingleInputSemanticProperties result = new SingleInputSemanticProperties();
        getSemanticPropsSingleFromString(result, forwarded, nonForwarded, read, inType, outType);
