Interface StreamableMacro

All Superinterfaces:

Macro

All Known Implementing Classes:

StreamableMacroAdapter

public interface StreamableMacro
extends Macro

Macro that consumes and produces Streamables instead of Strings. Streamable macros should be more efficient than a regular macro, especially in situations where the body of the macro is likely to be large, and processing on the body is either unnecessary or can be delayed until write time.

Error handling: MacroExecutionExceptions thrown from execute() will be handled normally, and the macro output will be replaced with the appropriate error message. This service is not available to the streamable's writeTo() method. If an error is likely to occur during streaming of the output, the macro must handle processing and displaying the error itself.

Method Detail

executeToStream

Streamable executeToStream(Map<String,String> parameters,
                           Streamable body,
                           ConversionContext context)
                    throws MacroExecutionException

Execute the macro, and produce a streamable that represents its output.

Parameters:

parameters - the parameters with which to execute the macro

body - the body of the macro provided as a streamable, processed according to Macro.getBodyType()

context - the conversion context of the current rendering pipeline

Returns:

a streamable representing the macro output

Throws:

MacroExecutionException - if a processing, parsing or parameter validation error occurs during parsing
