         color: #3E576F;
        Type Parameters:
        K - type for the key

        if style was set using setStyle(String), type will be String

        if style was set using setStyle(Map), type will be the same as the type from the key of the map

        V - type for the value

        if style was set using setStyle(String), type will be String

        if style was set using setStyle(Map), type will be the same as the type from the key of the map

      • setStyle

        public void setStyle​(String style)
        Sets shared generic CSS styles for all labels.

        This method allows simple settings like 

        
 label.setStyle("fontWeight: 'bold'; color: 'white'; textShadow: '0px 1px 2px black'");

        In the format of CSS key:value, and ";" separating multiple key:value pairs, if you have more a complex CSS styling, we recommend using setStyle(Map)

        Parameters:
        style - one or many CSS key:value pairs in a single line string format

      • setStyle

        public <K,​V> void setStyle​(Map<K,​V> style)
        Sets shared generic CSS styles for all labels.

        This method allows complex styling like: 

         
 Map<String, Object> styles = new HashMap<String, Object>();
 styles.put("fill", "#E8E8EA");
 styles.put("stroke", "#6E6E78");
 styles.put("stroke-width", "1");
 styles.put("r", "0");
 Map<String, Object> states = new HashMap<String, Object>();
 Map<String, String> hover = new HashMap<String, String>();
 hover.put("fill", "#F4F4F6");
 hover.put("stroke", "#6E6E78");
 hover.put("stroke-width", "1");
 hover.put("r", "0");
 states.put("hover", hover);
 styles.put("states", states);
 Map<String, String> style = new HashMap<String, String>();
 style.put("color", "#4D5663");
 style.put("fontSize", "12px");
 style.put("fontFamily", "'Arial'");
 style.put("fontWeight", "normal");
 style.put("padding", "10px");
 styles.put("style", style);
        which will generate the final results like: 
        
 {
     "fill": "#E8E8EA",
     "stroke": "#6E6E78",
     "stroke-width": "1",
     "r": "0",
     "states":
     {
         "hover":
         {
             "fill": "#F4F4F6",
             "stroke": "#6E6E78",
             "stroke-width": "1",
             "r": "0"
         }
     },
     "style":
     {
         "color": "#4D5663",
         "fontSize": "12px",
         "fontFamily": "'Arial'",
         "fontWeight": "normal",
         "padding": "10px"
     }
 }
        Type Parameters:
        K - Type for the key, usually String
        V - Type for the value, usually String. For nested maps, use Object or any other type.
