示例1: testAttribute
import org.eclipse.core.expressions.PropertyTester; //导入依赖的package包/类
/**
* Adds a way to check for the app_engine (currently hardcoded) property from this plugin.
*/
@Override
public boolean testAttribute(Object target, String name, String value) {
//For now let's leave it checking only app_engine, but this could grow if needed.
if ("app_engine".equals(name)) {

for (PropertyTester tester : propertyTesters) {
if (tester.test(target, name, null, value)) {

//If we didn't find what we were looking for, use the platform action filter
if (this.platformActionFilter != null) {
return this.platformActionFilter.testAttribute(target, name, value);
}
//if the platform didn't provide it, just return false.
return false;
}
示例2: getPropertyTestersFromPydevCustomizations
import org.eclipse.core.expressions.PropertyTester; //导入依赖的package包/类
/**
* Cache them after the 1st request for a given name.
*
* Gets the property testers in org.python.pydev.customizations that match the passed name.
