public class HtmlStyleCollection

extends java.lang.Object

The HtmlStyleCollection is used to create HtmlCellStyles and to convert these cell styles into Cascading StyleSheet code.

The collection reuses previously generated styles to create optimized code.

Created StyleSheets are stored in the collection and can be used as keys to lookup the name of that style in the global style sheet.
