SimpleRenameMap

public SimpleRenameMap(java.util.List<Attribute> originalAttrList,
                       java.util.List<Attribute> renamedAttrList)

Constructor.

Parameters:

originalAttrList - a list of original attributes

renamedAttrList - a list of renamed attributes

Method Detail

add

public void add(Attribute originalAttribute,
                Attribute renamedAttribute)

Adds the attribute mapping from original to renamed attribute. Attributes are cloned by this method before being stored.

Specified by:

add in interface RenameMap

Parameters:

originalAttribute - original (input) attribute

renamedAttribute - renamed (output) attribute

getOriginalAttribute

public Attribute getOriginalAttribute(Attribute renamedAttribute)
                               throws AmbiguousAttributeException,
                                      AmbiguousMappingException

Get original (input) attribute.

Specified by:

getOriginalAttribute in interface RenameMap

Parameters:

renamedAttribute - renamed (output) attribute

Returns:

original (input) attribute or null if no mapping exists

Throws:

AmbiguousAttributeException - when renamed attribute is not unique in the list of renamed attributes

AmbiguousMappingException - when an attribute could map to several original attributes if we would to ignore positioning

getRenamedAttribute

public Attribute getRenamedAttribute(Attribute originalAttribute)
                              throws AmbiguousAttributeException,
                                     AmbiguousMappingException

Get renamed (output) attribute.

Specified by:

getRenamedAttribute in interface RenameMap

Parameters:

originalAttribute - original (input) attribute

Returns:

renamed attribute or null if no mapping exists

Throws:

AmbiguousAttributeException - when original attribute is not unique in the list of original attributes

AmbiguousMappingException - when an attribute could map to several renamed attributes if we would to ignore positioning (id, id, id) -> (id, id, ident)

getOriginalAttributeList

public java.util.List<Attribute> getOriginalAttributeList()

Get an ordered list of original attributes.

Specified by:

getOriginalAttributeList in interface RenameMap

Returns:
