示例1: wrapCodeToMakeItSafe
import org.objectweb.asm.commons.GeneratorAdapter; //導入方法依賴的package包/類
/**
* Wrap the generated code in safe try-catch block.
*
* It creates an equivalent bytecode:
* <pre>
* <code>
* try {
* // Generated code will be here
* } catch (Throwable t) {
* // Ignore
* }
* </code>
* </pre>
*/
public static void wrapCodeToMakeItSafe(GeneratorAdapter mv, Runnable generatedCode) {
if (true) {
// TODO fix it
generatedCode.run();
return;
}
// Create labels and configure try-catch blocks
Label tryLabel = mv.newLabel();
Label catchLabel = mv.newLabel();
Label endLabel = mv.newLabel();
mv.visitTryCatchBlock(tryLabel, catchLabel, catchLabel, null);
// Start try block
mv.mark(tryLabel);
// === GENERATED CODE ===
generatedCode.run();
// === GENERATED CODE ===
// If code is executed successfully, go to the end
mv.goTo(endLabel);
// Start catch block
mv.mark(catchLabel);
// Just ignore this exception
mv.pop();
mv.mark(endLabel);
}
