virtual const char* SWFilter::getHeader ( ) const

inlinevirtualinherited

This method can supply a header associated with the processing done with this filter. A typical example is a suggested CSS style block for classed containers.

Reimplemented in OSISLaTeX, OSISXHTML, ThMLLaTeX, ThMLXHTML, TEIXHTML, GBFLaTeX, and GBFXHTML.
