Method Detail

getKeySize

public int getKeySize()
Returns the number of MappingFields that constitute the "gml:id".

Returns:
the number of MappingFields

getIdFields

public MappingField[] getIdFields()
Returns the MappingFields that are used to build the "gml:id".

Returns:
the id fields

getPrefix

public java.lang.String getPrefix()
Returns the prefix.

Returns:
the prefix

getSeparator

public java.lang.String getSeparator()
Returns the separator.

Returns:
the separator

getIdPartInfo

public MappedGMLId.IDPART_INFO getIdPartInfo()
Returns whether the configuration explicitly defines that the id has to be considered when two features are checked for equality.

Returns:
'identityPart' information

isIdentityPart

public boolean isIdentityPart()
Returns whether the id has to be considered when two features are checked for equality.

Returns:
true, if the feature id is part of the feature's identity

setIdentityPart

public void setIdentityPart(boolean isIdentityPart)
Sets the 'identiyPart' information.

Parameters:
isIdentityPart - set to true, if feature id should determine feature's identity solely

getIdGenerator

public IdGenerator getIdGenerator()
TODO remove this. Just a quick hack to make ParentIdGenerator work...

Returns:
IdGenerator that is used to generate new feature ids

generateFid

FeatureId generateFid(MappedFeatureType ft,
                      DatastoreTransaction ta)
                throws IdGenerationException
Generates a new and unique feature identifier.

Parameters:
ft -
ta -
Returns:
a new and unique feature identifier.
Throws:
IdGenerationException
