Going Deep: JSF Custom Components - JSF and HTML5 - page 150

On the component we will also have to implement getters and setters for the attributes that we want to expose
and collect from the page author. The attributes with description and default values can be found in Table 6-1 .

Table 6-1. Attributes for the Random Text Component

Attribute Description Default

textType Type of random text to generate gibberish

outputTag Type of HTML to generate. Either p for paragraphs or ul for unordered list. P

count Number of paragraphs or items to return 10

minWords Minimum number of words to return in each paragraph or item. 5

maxWords Maximum number of words to return in each paragraph or item. 10

Lastly, we will need a method for obtaining the random text. The method will collect the attributes and invoke
the RandomTextAPI. A complete listing of the RandomTextComponent can be found in Listing 6-3.
