public Map<String,Object> getExpressionObjects()
IProcessingContext
Returns the map of expression objects that should be made available to every expression evaluation operation (whenever variable evaluation is available). In OGNL and SpringEL expressions, these will be available as #object1, #object2, etc.
This method cannot return null, and must return a modifiable Map object (which will, in fact, be modified).

public IContext getContext()
IProcessingContext
Returns the current context specified for template processing.

public Object getExpressionEvaluationRoot()
IProcessingContext
Returns the current evaluation root. This is the object on which expressions (normal expressions, like those specified in the standard dialect with ${...}) are executed.
getExpressionEvaluationRoot
in interface IProcessingContext
public Object getExpressionSelectionEvaluationRoot()
IProcessingContext
Returns the current selection evaluation root. This is the object on which selection expressions (like those specified in the standard dialect with *{...}) are executed.

public boolean hasSelectionTarget()
IProcessingContext
Returns whether there currently is a selection going on (e.g. th:object in standard dialect).

public Object getSelectionTarget()
IProcessingContext
Returns the selection target object, and raises an exception if there isn't any.
Meant for internal use.
