Method Detail

getForwardingTargetFields

public FieldSet getForwardingTargetFields(int input,
                                          int sourceField)

Description copied from interface: SemanticProperties

Returns the indexes of all target fields to which a source field has been unmodified copied by a function.

Specified by:

getForwardingTargetFields in interface SemanticProperties

Overrides:

getForwardingTargetFields in class SingleInputSemanticProperties

Parameters:

input - The input id for the requested source field (0 for first input, 1 for second input)

sourceField - The index of the field for which the target position index is requested.

Returns:

A set containing the indexes of all target fields to which the source field has been unmodified copied.

getForwardingSourceField

public int getForwardingSourceField(int input,
                                    int targetField)

Description copied from interface: SemanticProperties

Returns the index of the source field on the given input from which the target field has been unmodified copied by a function.

Specified by:

getForwardingSourceField in interface SemanticProperties

Overrides:

getForwardingSourceField in class SingleInputSemanticProperties

Parameters:

input - The input id for the requested source field (0 for first input, 1 for second input)

targetField - The index of the target field to which the source field has been copied.

Returns:

The index of the source field on the given index that was copied to the given target field. -1 if the target field was not copied from any source field of the given input.

addForwardedField

public void addForwardedField(int sourceField,
                              int targetField)

Description copied from class: SingleInputSemanticProperties

Adds, to the existing information, a field that is forwarded directly from the source record(s) to the destination record(s).

Overrides:

addForwardedField in class SingleInputSemanticProperties

Parameters:

sourceField - the position in the source record(s)

targetField - the position in the destination record(s)
