Member Function Documentation

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.

Definition at line 62 of file swfilter.h.

{ return ""; }

virtual const char* SWOptionFilter::getOptionName ( )

inlinevirtualinherited

gets the name of the option of this filter

Returns

option name

Reimplemented in UTF8Transliterator.

Definition at line 72 of file swoptfilter.h.

{ return optName; }

virtual const char* SWOptionFilter::getOptionTip ( )

inlinevirtualinherited

gets a short explanation of the option of this filter; it could be presented to the user in frontend programs

Returns

option tip/explanation

Reimplemented in UTF8Transliterator.

Definition at line 78 of file swoptfilter.h.

{ return optTip; }

const char * SWOptionFilter::getOptionValue ( )

virtualinherited

Returns

The value of the current option.

Reimplemented in UTF8Transliterator.

Definition at line 62 of file swoptfilter.cpp.

                                           {
    return optionValue;
}

virtual StringList SWOptionFilter::getOptionValues ( )

inlinevirtualinherited

returns a list of the possible option values

Returns

list of option values

Reimplemented in UTF8Transliterator.

Definition at line 84 of file swoptfilter.h.

{ return *optValues; }

bool SWOptionFilter::isBoolean ( )

inlineinherited

many options are simple Off/On boolean type, and frontends may wish to show these with checkmarks or the like to the end user. This is a convenience method to allow a frontend to check if this filter has only Off/On values

Definition at line 67 of file swoptfilter.h.

{ return isBooleanVal; }

char ThMLHeadings::processText ( SWBuf &  text, const SWKey *  key = 0, const SWModule *  module = 0  )

virtual

This method processes and appropriately modifies the text given it for a particular filter task

Parameters

text	The text to be filtered/converted
key	Current key That was used.
module	Current module.

Returns

0

Implements SWFilter.

void SWOptionFilter::setOptionValue ( const char *  ival )

virtualinherited

sets the value of the option of this filter, e.g maybe a strong's filter might be set to "On" / "Off" - that would mean to show or not to show the strongs in the text, see also getOptionValues()

Parameters

ival	the new option value

Reimplemented in UTF8Transliterator.
