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

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

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

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

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

Return

boolean: True if the hash codes are equal and false if they are not equal.

GenerateAttributes()

        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
        use Libraries.Web.Page.Attribute
