public UberspectImpl()

Method Detail

init

public void init()
          throws Exception

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

Throws:

Exception

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
