<!ELEMENT markerId EMPTY>
<!ATTLIST markerId
markerIdValue CDATA #IMPLIED>
The markerId element is is used to get a custom problem marker for the custom validator implemented using this extension point
This markerId element also needs a corresponding problemMarker extension to be defined bythis validator with the same Id as the makerIdValue for the validator to have its own marker type. Here is an example of the a problemMarker extension defined for a markerIdValue "FooMarker"
<!ELEMENT facet EMPTY>
<!ATTLIST facet
facetId CDATA #IMPLIED>
This element is deprecated and enablement is the new recommended approach to filter validators based on facets.
<!ELEMENT enablement (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate , reference)*>
A generic root element. The element can be used inside an extension point to define its enablement expression. The children of an enablement expression are combined using the and operator.
<!ELEMENT not (not | and | or | instanceof | test | systemTest | equals | count | with | resolve | adapt | iterate | reference)>
This element represent a NOT operation on the result of evaluating it's sub-element expression.
<!ELEMENT and (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate , reference)*>
This element represent an AND operation on the result of evaluating all it's sub-elements expressions.
<!ELEMENT or (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate , reference)*>
This element represent an OR operation on the result of evaluating all it's sub-element expressions.
<!ELEMENT instanceof EMPTY>
<!ATTLIST instanceof
value CDATA #REQUIRED>
This element is used to perform an instanceof check of the object in focus. The expression returns EvaluationResult.TRUE if the object's type is a sub type of the type specified by the attribute value. Otherwise EvaluationResult.FALSE is returned.
<!ELEMENT test EMPTY>
<!ATTLIST test
property CDATA #REQUIRED
args CDATA #IMPLIED
value CDATA #IMPLIED
forcePluginActivation (true | false) >
This element is used to evaluate the property state of the object in focus. The set of testable properties can be extended using the propery tester extension point. The test expression returns EvaluationResult.NOT_LOADED if the property tester doing the actual testing isn't loaded yet and the attribute forcePluginActivation is set to false. If forcePluginActivation is set to true and the evaluation context used to evaluate this expression support plug-in activation then evaluating the property will result in activating the plug-in defining the tester.
<!ELEMENT systemTest EMPTY>
<!ATTLIST systemTest
property CDATA #REQUIRED
value CDATA #REQUIRED>
Tests a system property by calling the System.getProperty method and compares the result with the value specified through the value attribute.
<!ELEMENT equals EMPTY>
<!ATTLIST equals
value CDATA #REQUIRED>
This element is used to perform an equals check of the object in focus. The expression returns EvaluationResult.TRUE if the object is equal to the value provided by the attribute value. Otherwise EvaluationResult.FALSE is returned.
<!ELEMENT count EMPTY>
<!ATTLIST count
value CDATA #REQUIRED>
This element is used to test the number of elements in a collection.
<!ELEMENT with (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate , reference)*>
<!ATTLIST with
variable CDATA #REQUIRED>
This element changes the object to be inspected for all its child element to the object referenced by the given variable. If the variable can not be resolved then the expression will throw a ExpressionException when evaluating it. The children of a with expression are combined using the and operator.
<!ELEMENT resolve (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate , reference)*>
<!ATTLIST resolve
variable CDATA #REQUIRED
args CDATA #IMPLIED>
This element changes the object to be inspected for all its child element to the object referenced by the given variable. If the variable can not be resolved then the expression will throw a ExpressionException when evaluating it. The children of a with expression are combined using the and operator.
<!ELEMENT adapt (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate , reference)*>
<!ATTLIST adapt
type CDATA #REQUIRED>
This element is used to adapt the object in focus to the type specified by the attribute type. The expression returns not loaded if either the adapter or the type referenced isn't loaded yet. It throws a ExpressionException during evaluation if the type name doesn't exist at all. The children of an adapt expression are combined using the and operator.
<!ELEMENT iterate (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate , reference)*>
<!ATTLIST iterate
operator (or|and)
ifEmpty (true | false) >
This element is used to iterate over a variable that is of type java.util.Collection. If the object in focus is not of type java.util.Collection then an ExpressionException will be thrown while evaluating the expression.
<!ELEMENT reference EMPTY>
<!ATTLIST reference
definitionId IDREF #REQUIRED>
This element is used to reference an expression from the org.eclipse.core.expressions.definitions extension point. The expression definition will be evaluated within the current expression element using the current evaluation context.
