Constructor Detail

VectorToken

public VectorToken(org.geotools.data.simple.SimpleFeatureCollection features)
            throws IllegalActionException

Create a new VectorToken from a set of features.

Throws:

IllegalActionException

VectorToken

public VectorToken(org.geotools.data.simple.SimpleFeatureSource source,
                   org.opengis.referencing.crs.CoordinateReferenceSystem defaultCRS)

Create a new VectorToken from a feature source.

Parameters:

source - A data source for the features.

defaultCRS - Coordinate reference system to use if not defined by the source.

VectorToken

public VectorToken(java.lang.String string)

Method Detail

getVectors

public org.geotools.data.simple.SimpleFeatureCollection getVectors()
                                                            throws IllegalActionException

Get the set of features represented in this token. NOTE: if you need to modify the features, make a copy first.

Throws:

IllegalActionException

getFilteredVectors

public org.geotools.data.simple.SimpleFeatureCollection getFilteredVectors(org.opengis.filter.Filter filter)
                                                                    throws IllegalActionException

Get the filtered set of features represented in this token. NOTE: if you need to modify the features, make a copy first.

Parameters:

filter - A filter to select a subset of the features.

Throws:

IllegalActionException

getType

public Type getType()

Get the token type.

Overrides:

getType in class Token

Returns:

BaseType.GENERAL

isEqualTo

public final BooleanToken isEqualTo(Token rightArgument)
                             throws IllegalActionException

Test for equality of the values of this Token and the argument Token. If the value of this token or the value of the rightArgument token is null, then we return False.

Overrides:

isEqualTo in class Token

Parameters:

rightArgument - The Token to test against.

Returns:

A boolean token that contains the value true if the dates are the same.

Throws:

IllegalActionException - Not thrown in this base class.

toString

public java.lang.String toString()

Return a String representation of the VectorToken.

Overrides:

toString in class Token

Returns:

The String "present", unless this token is Token.NIL, in which case return the String "nil".
