Field Detail

### log

    protected Log log

  Our runtime logger.

### introspector

    protected Introspector introspector

  the default Velocity introspector

Constructor Detail

### UberspectImpl

    public UberspectImpl()

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`

### setLog

    public void setLog(Log log)

  Sets the runtime logger - this must be called before anything else.

  Specified by:
    `setLog` in interface `UberspectLoggable`
  Parameters:
    `log` - The logger instance to use.
  Since:
    1.5

### setRuntimeLogger

    public void setRuntimeLogger(RuntimeLogger runtimeLogger)

  Deprecated. Use setLog(Log log) instead.

  Specified by:
    `setRuntimeLogger` in interface `UberspectLoggable`
  Parameters:
    `runtimeLogger` -

### getIterator

    public Iterator getIterator(Object obj,
                                Info i)
                         throws Exception

  To support iterative objects used in a `#foreach()` loop.

  Specified by:
    `getIterator` in interface `Uberspect`
  Parameters:
    `obj` - The iterative object.
    `i` - Info about the object's location.
  Returns:
    An `Iterator` object.
  Throws:
    `Exception`

### getMethod

    public VelMethod getMethod(Object obj,
                               String methodName,
                               Object[] args,
                               Info i)
                        throws Exception

    `getMethod` in interface `Uberspect`
  Parameters:
    `obj` -
    `methodName` -
    `args` -
    `i` -
  Returns:
    A Velocity Method.
  Throws:
    `Exception`

### getPropertyGet

    public VelPropertyGet getPropertyGet(Object obj,
                                         String identifier,
                                         Info i)
                                  throws Exception

  Throws:
    `Exception`

### getPropertySet

    public VelPropertySet getPropertySet(Object obj,
                                         String identifier,
                                         Object arg,
