Parameters

Example

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

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.

Example


use Libraries.Web.Page.AttributeAccepter
use Libraries.Web.Page.Attribute

AttributeAccepter accept
accept:AddAttribute("src", "http://www.google.com")

AddClassAttribute(text value)

Adds to the ClassAttribute attribute. Multiple class names can be listed in the passed text, separated by a space.

Parameters

  • text value: The classes to be added to the element

Example



use Libraries.Web.Page.GlobalAttributeAccepter
use Libraries.Web.Page.Attribute

GlobalAttributeAccepter accept
accept:AddClassAttribute("myClass")

AddNestedTag(Libraries.Web.Page.WebTag tag)

This action adds a WebTag to the list of WebTags contained within the current WebTag.

Parameters

Example

use Libraries.Web.Page.TableRow
use Libraries.Web.Page.TableData


//TableRow and TableData are both WebTags
TableRow row
TableData cell
cell:SetDescription("name")
row:Add(cell)

AddText(text value)

This action sets the description text for this WebTag.

Parameters

  • text value: The text contained in the WebTag.

Example

use Libraries.Web.Page.TableRow
use Libraries.Web.Page.TableData

//TableRow and TableData are both WebTags
TableRow row
TableData cell
cell:AddDescription("name")

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.

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Example

Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Parameters

Return

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

Example

use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)
