build

public java.lang.Object build(DirectiveBuilder builder,
                              BuildContext bc)
                       throws BuildException

Description copied from class: Directive

Directives must implement a build() method. The build method should examine the directive arguments (available through the DirectiveBuilder) and return a macro describing the built directive. In most cases, build() will just set up the directive's private fields and return 'this', but in some cases, no macro needs be returned (such as directives with only side effects on the build context) or some other macro may be returned (such as in the case of "#if (true) { }" -- no IfDirective object need be returned, just return the block.)

Specified by:

build in class Directive

Throws:

BuildException

write

public void write(FastWriter out,
                  Context context)
           throws PropertyException,
                  java.io.IOException

Description copied from interface: Macro

Interpret the directive and write it out, using the values in the supplied context as appropriate.

Throws:

java.io.IOException - if we could not successfully write to out

PropertyException - if required data was missing from context
