Method Detail

getPriority

int getPriority()

The priority of execution relative to the other Macros. The lowest values have the highest priorities and execute first. For example a Macro with a priority of 100 will execute before one with a priority of 500.

Returns:

the execution priority

getDescriptor

MacroDescriptor getDescriptor()

Returns:

the macro descriptor

supportsInlineMode

boolean supportsInlineMode()

Returns:

true if the macro can be inserted in some existing content such as a paragraph, a list item etc. For example if I have == hello {{velocity}}world{{/velocity}} then the Velocity macro must support the inline mode and not generate a paragraph.

execute

List<Block> execute(P parameters,
                    String content,
                    MacroTransformationContext context)
                    throws MacroExecutionException

Executes the macro.

Parameters:

parameters - the macro parameters in the form of a bean defined by the Macro implementation

content - the content of the macro

context - the context of the macros transformation process

Returns:

the result of the macro execution as a list of Block elements

Throws:

MacroExecutionException - error when executing the macro
