PDF page headers/footers definition options

Hai everyone, how to implement this java code below into cfscript?

PD4PageMark footer = new PD4PageMark() {
public String getHtmlTemplate(int pageNumber) {
if ( pageNumber % 2 == 0 ) {
return “some left aligned stuff…”;
} else {
return “some right aligned stuff…”;
}
}
};
pd4ml.setPageFooter(footer);
