Class DefaultModelAdaptor

java.lang.Object

com.floreysoft.jmte.DefaultModelAdaptor

All Implemented Interfaces:

ModelAdaptor

public class DefaultModelAdaptor
extends Object
implements ModelAdaptor

Default implementation of the model adapter.

Does the object traversal using the "." operator. Resolved value will be checked if it is either a Processor or a Callable in which case the final resolved value is computed by calling those executable objects.

Inherit from this adapter if you want a slight change of this behavior and set your new adaptor on the engine Engine.setModelAdaptor(ModelAdaptor) .

                       String expression)

Description copied from interface: ModelAdaptor

Gets a value from the model.

Specified by:

getValue in interface ModelAdaptor

Parameters:

context - the current context including the scoped model

token - the token that asks for this value (e.g. used for error reporting)

segments - an already split version of the expression for faster processing

expression - the expression describing the desired value

Returns:

the value

getIterable

public Iterable<Object> getIterable(Object value)

Description copied from interface: ModelAdaptor

Gets an iterable for an arbitrary value.

Specified by:

getIterable in interface ModelAdaptor

Parameters:

value - the value to get the iterable for

Returns:

a matching iterable

getSpecialIteratorVariable

public String getSpecialIteratorVariable()

Description copied from interface: ModelAdaptor

Gets the name of the special iterator variable which will be used as an alternative variable name of the iterator in a foreach loop. E.g. something like it.

Specified by:

getSpecialIteratorVariable in interface ModelAdaptor

Returns:

name of the special iterator variable
