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

getConversionHandler

public TypeConversionHandler getConversionHandler()

setRuntimeServices

public void setRuntimeServices(RuntimeServices rs)

sets the runtime services

Specified by:

setRuntimeServices in interface RuntimeServicesAware

Parameters:

rs - runtime services

setLog

public void setLog(org.slf4j.Logger log)

Deprecated. logger is now set by default to the namespace logger "velocity.rendering".

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

Parameters:

log - The logger instance to use.

Since:

1.5

getIterator

public Iterator getIterator(Object obj,
                            Info i)

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.

getMethod

public VelMethod getMethod(Object obj,
                           String methodName,
