<!ELEMENT enablement (not , and , or , instanceof , test , systemTest , equals , count , with , resolve , adapt , iterate)*>
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)>
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)*>
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)*>
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>
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 teh property tester doing the actual testing isn't loaded yet.
<!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)*>
<!ATTLIST with
variable CDATA #REQUIRED>
This element changes the object to be inspected for all its child element to the object referneced 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)*>
<!ATTLIST resolve
variable CDATA #REQUIRED
args CDATA #IMPLIED>
This element changes the object to be inspected for all its child element to the object referneced 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)*>
<!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)*>
<!ATTLIST iterate
operator (or|and) >
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.
