Examples with ArrayType com.sun.jdi.ArrayType used on opensource projects

Example 1 with ArrayType

use of com.sun.jdi.ArrayType in project jdk8u_jdk by JetBrains.

the class OomDebugTest method test2.

/*
     * Test case: Array reference as method parameter.
     */
// called via reflection
@SuppressWarnings("unused")
private void test2() throws Exception {
    System.out.println("DEBUG: ------------> Running test2");
    try {
        Field field = targetClass.fieldByName("byteArray");
        ArrayType arrType = (ArrayType) field.type();
        for (int i = 0; i < 15; i++) {
            ArrayReference byteArrayVal = arrType.newInstance(3000000);
            if (byteArrayVal.isCollected()) {
                System.out.println("DEBUG: Object got GC'ed before we can use it. NO-OP.");
                continue;
            }
            invoke("testPrimitive", "([B)V", byteArrayVal);
        }
    } catch (VMOutOfMemoryException e) {
        defaultHandleOOMFailure(e);
    }
}

Example 2 with ArrayType

use of com.sun.jdi.ArrayType in project che by eclipse.

the class Evaluator method isAssignable.

private boolean isAssignable(Type from, Type to) {
    if (from.equals(to)) {
        return true;
    }
    if (from instanceof BooleanType) {
        return to instanceof BooleanType;
    }
    if (to instanceof BooleanType) {
        return false;
    }
    if (from instanceof PrimitiveType) {
        return to instanceof PrimitiveType;
    }
    if (to instanceof PrimitiveType) {
        return false;
    }
    if (from instanceof ArrayType) {
        if (to instanceof ArrayType) {
            Type fromArrayComponent;
            Type toArrayComponent;
            try {
                fromArrayComponent = ((ArrayType) from).componentType();
                toArrayComponent = ((ArrayType) to).componentType();
            } catch (ClassNotLoadedException e) {
                return false;
            }
            if (fromArrayComponent instanceof PrimitiveType) {
                return fromArrayComponent.equals(toArrayComponent);
            }
            return !(toArrayComponent instanceof PrimitiveType) && isAssignable(fromArrayComponent, toArrayComponent);
        }
        return to.name().equals("java.lang.Object");
    }
    if (from instanceof ClassType) {
        ClassType superClass = ((ClassType) from).superclass();
        if (superClass != null && isAssignable(superClass, to)) {
            return true;
        }
        for (InterfaceType interfaceType : ((ClassType) from).interfaces()) {
            if (isAssignable(interfaceType, to)) {
                return true;
            }
        }
    }
    for (InterfaceType interfaceType : ((InterfaceType) from).subinterfaces()) {
        if (isAssignable(interfaceType, to)) {
            return true;
        }
    }
    return false;
}

Example 3 with ArrayType

use of com.sun.jdi.ArrayType in project intellij-community by JetBrains.

the class JumpToTypeSourceAction method getObjectType.

@Nullable
private static ReferenceType getObjectType(@NotNull ReferenceType ref) {
    if (!(ref instanceof ArrayType)) {
        return ref;
    }
    final String elementTypeName = ref.name().replace("[]", "");
    final VirtualMachine vm = ref.virtualMachine();
    final List<ReferenceType> referenceTypes = vm.classesByName(elementTypeName);
    if (referenceTypes.size() == 1) {
        return referenceTypes.get(0);
    }
    return null;
}
