Libraries.Web.Page.WindowAttributeAccepter Documentation
The WindowAttributeAccepter class is designed as a helper to ease adding and removing window event attributes from particular WebTag objects. While there is no harm in creating an object of this type, it is used most commonly by sub-classes that need to use attributes. The example for this class shows how to subclass the WindowAttributeAccepter class.
Example Code
use Libraries.Web.Page.WindowAttributeAccepter
class body is WindowAttributeAccepter, WebGenerator
action Generate returns text
text result = "<body "
result = result + GenerateAttributes()
result = result + ">
"
result = result + me:GenerateNestedTags()
result = result + "</body>"
return result
end
end
Inherits from: Libraries.Web.Page.AttributeAccepter, Libraries.Language.Object

Actions Documentation
Add(Libraries.Web.Page.Attribute attribute)
This action adds an attribute to this object. If an attribute with the same name as
Example Code
use Libraries.Web.Page.AttributeAccepter
use Libraries.Web.Page.Attribute
Attribute attribute
attribute:SetName("src")
attribute:SetValue("http://www.google.com")
AttributeAccepter accept
accept:Add(attribute)
Parameters
- Libraries.Web.Page.Attribute: The attribute that will be stored.
AddAttribute(text name, text value)
This action adds an attribute to this object. This action is a helper action, which essentially does the same thing as the Add(Attribute) action. If an attribute with the same name as
Example Code
use Libraries.Web.Page.AttributeAccepter
use Libraries.Web.Page.Attribute
AttributeAccepter accept
accept:AddAttribute("src", "http://www.google.com")
Parameters
- text name: The name of the attribute functions as a key. For example, in a link, we might have a "src" and an actual address, like google.com. In this case, the name would be equivalent to the src.
- text value: As an example of link, imagine we have a value of "src" and an actual address, like google.com. In this case, the value would be equivalent to google.com.
Compare(Libraries.Language.Object object)
This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.
Example Code
Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)
Parameters
- Libraries.Language.Object: The object to compare to.
Return
integer: The Compare result, Smaller, Equal, or Larger.
Equals(Libraries.Language.Object object)
This action determines if two objects are equal based on their hash code values.
Example Code
use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)
Parameters
- Libraries.Language.Object: The to be compared.
Return
boolean: True if the hash codes are equal and false if they are not equal.
GenerateAttributes()
This action returns a text description of all attributes stored.
Example Code
use Libraries.Web.Page.AttributeAccepter

text result = accept:GenerateAttributes()
Return
text:
GetAttribute(text name)
This action returns an attribute from this object's Attributes object. If no attribute exists for a given key, this action returns undefined.
Example Code
use Libraries.Web.Page.AttributeAccepter

AttributeAccepter accept
//as we have not set any attribute, this would
//return undefined
Attribute attribute = accept:GetAttribute("src")
Parameters
Return
GetAttributeValue(text name)
