---------------------------------------
Summary: Remove deprecated dimension attributes from
OperationMethod
Key: SIS-585
URL: https://issues.apache.org/jira/browse/SIS-585
Project: Spatial Information Systems
Issue Type: Task
Components: Referencing
Affects Versions: 1.3, 1.2, 1.1
Reporter: Martin Desruisseaux
Assignee: Martin Desruisseaux
Fix For: 1.4
The following methods are derived from {{CC_OperationMethod}} attributes
present in ISO 19111:2007 but removed in ISO 19111:2019 (note that
{{MathTransform}} has attributes of the same name, which are not affected):
* {{getSourceDimensions()}}
* {{getTargetDimensions()}}
Those methods have been deprecated in SIS 1.1, but they were still there in SIS
1.2 and 1.3 because removing those attributes actually implies an amount of
changes much larger than only the {{DefaultOperationMethod}} class. Now it is
time to remove those attributes, because they are blocking other tasks such as
SIS-584. The reason for that is because the management of the number of
dimensions of an {{OperationMethod}} is actually a difficult task, which
required hacks in the way we discover providers with
{{java.util.ServiceLoader}}.
Removing above-cited methods (actually make them returning {{null}} in most
cases but not all) allow the removal of non-trivial code and SQL queries in
{{EPSGFactory}} which were trying to discover the number of dimensions of an
operation method. Various other classes got significant complexity removal too.
