Constructor Detail

FeatureId

public FeatureId(MappedFeatureType ft,
                 Object[] values)

Creates a new instance of FeatureId from the given parameters.

Parameters:

ft - cannot be null, must not be an abstract feature type

values - cannot be null or empty

FeatureId

public FeatureId(MappedFeatureType ft,
                 String fid)
          throws IdGenerationException

Creates a new instance of FeatureId from the given parameters.

Parameters:

ft - cannot be null, must not be an abstract feature type

fid - cannot be null

Throws:

IdGenerationException

Method Detail

getFeatureType

public MappedFeatureType getFeatureType()

Return the MappedFeatureType of the identified feature.

The feature type is concrete, never abstract.

Returns:

type of the identified feature, never abstract

getFidDefinition

public MappedGMLId getFidDefinition()

Return the underlying MappedGMLId.

Returns:

MappedGMLId

getLength

public int getLength()

Returns the number of components that the key consists of.

Returns:

the number of components that the key consists of

getValues

public Object[] getValues()

Returns all column values of the key.

Returns:

all column values of the key

getValue

public Object getValue(int i)

Returns a certain column value of the key.

Parameters:

i - requested column

Returns:

the requested column value of the key

getAsString

public String getAsString()

Returns the canonical textual representation, i.e. the key components, separated by the separator defined in the associated MappedGMLId.

Returns:

the canonical textual representation

compareTo

public int compareTo(FeatureId that)

Specified by:

compareTo in interface Comparable<FeatureId>

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Returns a string representation of the object.

Overrides:

toString in class Object

Returns:

a string representation of the object

removeFIDPrefix

public static Object removeFIDPrefix(String id,
                                     MappedGMLId idMapping)
                              throws IdGenerationException

Removes the prefix from the given feature id.

The prefix is taken from the given gml:id mapping.

Parameters:

id - feature id (including prefix).

idMapping - target gml:id mapping (where the fid will be stored)

Returns:

feature id (without prefix) as an object of the right type (matching the table column)

Throws:

IdGenerationException - if the given fid does not begin with the expected prefix from the gml:id mapping
