Interface ITemplateBoundariesStructureHandler

All Known Implementing Classes:

TemplateBoundariesStructureHandler

public interface ITemplateBoundariesStructureHandler

Structure handler class meant to be used by ITemplateBoundariesProcessor implementations.

Structure handlers allow processors to instruct the engine to perform a series of actions that cannot be done directly from the processors themselves, usually because these actions are applied or have effects on scopes broader than the processed events themselves.

Since:

3.0.0

Method Detail

reset

void reset()

Resets all actions specified so far for the current processor execution.

setLocalVariable

void setLocalVariable(String name,
                      Object value)

Instructs the engine to set a new local variable.

Parameters:

name - the name of the variable.

value - the value of the variable.

removeLocalVariable

void removeLocalVariable(String name)

Instructs the engine to remove a local variable.

Parameters:

name - the name of the variable.

setSelectionTarget

void setSelectionTarget(Object selectionTarget)

Instructs the engine to set a new selection target.

The selection target is the object on which selection expressions (*{...}) are executed. In the Standard Dialect, this selection target is usually modified by means of the th:object attribute, but custom processors can do it too. Note the selection target has the same scope as a local variable, and will therefore be accessible only inside the body of the element being processed.

See ITemplateContext.getSelectionTarget()

Parameters:

selectionTarget - the selection target to be set.

setInliner

void setInliner(IInliner inliner)

Instructs the engine to set a new inliner.

Inliners are used for processing all text nodes (IText events) appearing in the body of the element being processed. This is the mechanism used by the th:inline attribute to enable inlining in any of the specified modes (text, javascript, etc).

See ITemplateContext.getInliner()

Parameters:

inliner - the inliner.

insert

void insert(String text,
            boolean processable)

Instructs the engine to insert the specified text.

If the processed event is a ITemplateStart event, then the text will be inserted at the beginning of the template (just after the template start event). On the other hand, if the processed event is a ITemplateEnd event, then the text will be inserted at the end of the template (just before the template end event).

Parameters:

text - the text to be inserted.

processable - whether the inserted text should be considered processable or not.

insert

void insert(IModel model,
            boolean processable)

Instructs the engine to insert the specified model.

If the processed event is a ITemplateStart event, then the model will be inserted at the beginning of the template (just after the template start event). On the other hand, if the processed event is a ITemplateEnd event, then the model will be inserted at the end of the template (just before the template end event).

Parameters:

model - the model to be inserted.

processable - whether the inserted text should be considered processable or not.
