public static DualInputSemanticProperties createProjectionPropertiesDual(int[] fields,
                                                         boolean[] isFromFirst,
                                                         TypeInformation<?> inType1,
                                                         TypeInformation<?> inType2)

addSourceFieldOffset

public static SingleInputSemanticProperties addSourceFieldOffset(SingleInputSemanticProperties props,
                                                 int numInputFields,
                                                 int offset)

Creates SemanticProperties by adding an offset to each input field index of the given SemanticProperties.

Parameters:

props - The SemanticProperties to which the offset is added.

numInputFields - The original number of fields of the input.

offset - The offset that is added to each input field index.

Returns:

New SemanticProperties with added offset.

addSourceFieldOffsets

public static DualInputSemanticProperties addSourceFieldOffsets(DualInputSemanticProperties props,
                                                int numInputFields1,
                                                int numInputFields2,

                                                int offset2)

Creates SemanticProperties by adding offsets to each input field index of the given SemanticProperties.

Parameters:

props - The SemanticProperties to which the offset is added.

numInputFields1 - The original number of fields of the first input.

numInputFields2 - The original number of fields of the second input.

offset1 - The offset that is added to each input field index of the first input.

offset2 - The offset that is added to each input field index of the second input.

Returns:

New SemanticProperties with added offsets.
