IIRC "isComponentType" is available only for flow/simple containers.
And if there is any error in "canDelete" script, we consider this as "false".
In other scripts you have only ReflectionUtils class.
But actually all this can be done using ReflectionUtils, see org.eclipse.wb.internal.core.model.generic.ContainerObjectValidators.DEF_functions
[code][ private static final String DEF_functions = StringUtils.join(new String[]{
"def isModelType(model, c) {",
" if (c is String) {",
" return ReflectionUtils.isSuccessorOf((Class) model.description.componentClass, c);",
" } else {",
" return c.isAssignableFrom(model.description.componentClass);",
" }",
"};",
"def isSuccessorOf(o, c) {",
" if (c is String) {",
" return ReflectionUtils.isSuccessorOf(o, c);",
" } else {",
" return o != null && c.isAssignableFrom(o.getClass());",
" }",
"};",
"def isComponentType(c) {",
" return isModelType(component, c);",
"};",
"def isReferenceType(c) {",
" return isModelType(reference, c);",
"};",
"def isContainerType(c) {",
" return isModelType(container, c);",
"};",
"def isContainerThis() {",
" return isSuccessorOf(container.creationSupport, "
+ "'org.eclipse.wb.internal.core.model.creation.ThisCreationSupport');",
"};",}, "\n");
/code]
