Field Detail

MILLISECOND

public static javax.units.Unit MILLISECOND
Unit for milliseconds. Usefull for conversion from and to Date objects.

Constructor Detail

DefaultTemporalCRS

public DefaultTemporalCRS(org.opengis.referencing.crs.TemporalCRS crs)
Constructs a new temporal CRS with the same values than the specified one. This copy constructor provides a way to wrap an arbitrary implementation into a Geotools one or a user-defined one (as a subclass), usually in order to leverage some implementation-specific API. This constructor performs a shallow copy, i.e. the properties are not cloned.

Since:
2.2

DefaultTemporalCRS

public DefaultTemporalCRS(java.lang.String name,
                          org.opengis.referencing.datum.TemporalDatum datum,
                          org.opengis.referencing.cs.TimeCS cs)
Constructs a temporal CRS from a name.

Parameters:
name - The name.
datum - The datum.
cs - The coordinate system.

DefaultTemporalCRS

public DefaultTemporalCRS(java.util.Map properties,
                          org.opengis.referencing.datum.TemporalDatum datum,
                          org.opengis.referencing.cs.TimeCS cs)
Constructs a temporal CRS from a set of properties. The properties are given unchanged to the super-class constructor.

Parameters:
properties - Set of properties. Should contains at least "name".
cs - The coordinate system.
datum - The datum.
Method Detail

wrap

public static DefaultTemporalCRS wrap(org.opengis.referencing.crs.TemporalCRS crs)
Wraps an arbitrary temporal CRS into a Geotools implementation. This method is usefull if the user wants to take advantage of toDate(double) and toValue(java.util.Date) methods. If the supplied CRS is already an instance of or is , then it is returned unchanged.


toDate

public java.util.Date toDate(double value)
Convert the given value into a Date object. This method is the converse of toValue(java.util.Date).

Parameters:
value - A value in this axis unit.
Returns:
The value as a date.

toValue

public double toValue(java.util.Date time)
Convert the given date into a value in this axis unit. This method is the converse of toDate(double).

Parameters:
time - The value as a date.
Returns:
value A value in this axis unit.

hashCode

public int hashCode()
Returns a hash value for this geographic CRS.

Overrides:
hashCode in class AbstractSingleCRS
Returns:
The hash code value. This value doesn't need to be the same in past or future versions of this class.
