Method Details

setLastElement

void setLastElement(Element element)

Sets the latest target element of this response. This method is called repeatedly by the engine to make it possible to trace which elements have been processed.

Parameters:

element - an element that has been executed in the context of this response

Since:

1.0

getLastElement

Element getLastElement()

Retrieves the element that was last processed with

Returns:

the last element

Since:

1.0

enableTextBuffer

void enableTextBuffer(boolean enabled)

Enables or disabled the text output buffer.

The buffer is enabled by default and its buffered contents will be flushed when the buffer is disabled.

Parameters:

enabled - true to enable the text buffer; or

false to disable it

Since:

1.0

isTextBufferEnabled

boolean isTextBufferEnabled()

Indicates whether the text output buffer is enabled.

Returns:

true when the text buffer is enabled; or

false when it is disabled.

Since:

1.0

print

void print(Template template)
    throws EngineException

Prints the content of a template to the request text output.

Parameters:

template - the template that will be printed

Throws:

EngineException - if an error occurs during the output of the template content

Since:

1.0

• print(Collection)
• print(Object)

print

void print(Collection<CharSequence> deferredContent)
    throws EngineException

Prints a list of text snippets to the request text output.

Parameters:

deferredContent - the text snippets that will be printed

Throws:

EngineException - if an error occurs during the output of the text snippets // * @see #print(Template)

Since:

1.0

See Also:

• print(Object)

print

void print(Object value)
    throws EngineException

Prints the string representation of an object to the request text output. The string representation will be created through a String.valueOf(value) call.

Parameters:

value - the object that will be output

Throws:

EngineException - if an error occurs during the output of the content // * @see #print(Template)

Since:

1.0
