SecureUberspector (Apache Velocity 2.4 API)

java.lang.Object
- org.apache.velocity.util.introspection.UberspectImpl
- - org.apache.velocity.util.introspection.SecureUberspector

All Implemented Interfaces:

Uberspect, RuntimeServicesAware
```
public class SecureUberspector
extends UberspectImpl
```
Use a custom introspector that prevents classloader related method calls. Use this introspector for situations in which template writers are numerous or untrusted. Specifically, this introspector prevents creation of arbitrary objects or reflection on objects.
To use this introspector, set the following property:
```
 introspector.uberspect.class = org.apache.velocity.util.introspection.SecureUberspector
 
```

public SecureUberspector()
```
- Method Detail
  - init
```
public void init()
```
    init - generates the Introspector. As the setup code makes sure that the log gets set before this is called, we can initialize the Introspector using the log object.
    
    Specified by:
    
    init in interface Uberspect
    
    Overrides:
    
    init in class UberspectImpl
  - getIterator
```
public Iterator getIterator(Object obj,
                            Info i)
```
    Get an iterator from the given object. Since the superclass method this secure version checks for execute permission.
    
    Specified by:
    
    getIterator in interface Uberspect
    
    Overrides:
    
    getIterator in class UberspectImpl
    
    Parameters:
    
    obj - object to iterate over
    
    i - line, column, template info
    
    Returns:
    
    Iterator for object
