public class AbstractDerivedCRS
A coordinate reference system that is defined by its coordinate conversion from another coordinate reference system (not by a datum).
This class is conceptually abstract, even if it is technically possible to
instantiate it. Typical applications should create instances of the most specific subclass with
Default
prefix instead. An exception to this rule may occurs when it is not possible to
identify the exact type.

"conversionType"
property to be given to the constructor. The value should
be one of PlanarProjection.class
,
CylindricalProjection.class
or
ConicProjection.class
.
This is a Geotools specific property used as a hint for creating a projection of proper type from a defining conversion. In many cases, this hint is not needed since Geotools is often capable to infer it. This hint is used mostly by advanced factories like the EPSG backed one.
DefaultConversion.create(org.opengis.referencing.operation.Conversion, org.opengis.referencing.crs.CoordinateReferenceSystem, org.opengis.referencing.crs.CoordinateReferenceSystem, org.opengis.referencing.operation.MathTransform, java.lang.Class extends org.opengis.referencing.operation.Conversion>)

method. This field
contains a boolean
flag set to true
when a comparaison is in progress.
This lock is necessary because AbstractDerivedCRS
objects contain a
conversionFromBase
field, which contains a AbstractCoordinateOperation.targetCRS
field set to this AbstractDerivedCRS
object.
DO NOT USE THIS FIELD. It is strictly for internal use by equals(org.geotools.referencing.AbstractIdentifiedObject, boolean)
and
AbstractCoordinateOperation.equals(org.geotools.referencing.AbstractIdentifiedObject, boolean)
methods.
