| + | ===== The <attributeAssessment> Element ===== | ||
| + | ==== Definition and Usage ==== | ||
| + | |||
| + | The [[attributeassessment|<attributeAssessment>]] element is used to define a variable to be | ||
| + | evaluated, in [[assessmentstatement|<assessmentStatement>]] elements, against other variable | ||
| + | values or an absolute value. | ||
| + | |||
| + | The variable can be a property specifies in a [[property|<property>]] element, or | ||
| + | can be a (presentation, selection or attribution) event attribute: | ||
| + | occurrences, repetition or state (which has the following values: | ||
| + | "occurring", "paused", or "sleeping"). | ||
| + | |||
| + | The [[attributeassessment|<attributeAssessment>]]element has a //role// attribute, which | ||
| + | has to be unique in the connector role set. This attribute is the connector | ||
| + | interface point, which is associated to node interfaces ([[port|<port>]], | ||
| + | [[area|<area>]], [[property|<property>]] or [[switchport|<switchPort>]] elements) by a [[link|<link>]] | ||
| + | that refers to the connector. | ||
| + | |||
| + | The variable defined by the element depends on its //eventType// | ||
| + | attribute and its //attributeType// attribute: | ||
| + | |||
| + | * If the eventType value is "presentation", the //attributeType// | ||
| + | attribute may specifyas variable:the "occurrences" or "repetition" event | ||
| + | attributes,or the "state" event state. | ||
| + | |||
| + | * If the eventType is "attribution" the //attributeType// may have the | ||
| + | values: "nodeProperty" (specifying a node property), "occurrences", | ||
| + | "repetition" or "state". | ||
| + | |||
| + | * If the eventType value is "selection", the [[attributeassessment|<attributeAssessment>]]can | ||
| + | also define to which selection apparatus (for example, keyboard keys or | ||
| + | remote control keys) it refers, through its //key// attribute. The | ||
| + | //attributeType// attribute may have the values: "occurrences" | ||
| + | (default) or "state". | ||
| + | |||
| + | An offset value may be added to an [[attributeassessment|<attributeAssessment>]] before its | ||
| + | comparison in an [[assessmentstatement|<assessmentStatement>]] element. For example, an offset | ||
| + | may be added to an //attributeassessment// to specify: "the screen | ||
| + | vertical position plus 50 pixels". | ||

| + | | //role// | String. | The //role// attribute defines a connector interface point, which is associated to node interfaces by a link that refers to the connector. The //role// value must be unique within the set of roles of the connector. | | ||
| + | | //eventType// | "presentation", "selection", or "attribution". | The //eventType// attribute identifies the type of event for the action or condition. | | ||
| + | | //key// | At least the following values (case sensitive) must be accepted for the key attribute: "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "*", "#", "MENU", "INFO", "GUIDE", "CURSOR_DOWN", "CURSOR_LEFT", "CURSOR_RIGHT", "CURSOR_UP", "CHANNEL_DOWN", "CHANNEL_UP", "VOLUME_DOWN", "VOLUME_UP", "ENTER", "RED", "GREEN", "YELLOW", "BLUE", "BACK", "EXIT", "POWER", "REWIND", "STOP", "EJECT", "PLAY", "RECORD", and "PAUSE". | The //key// attribute identifies the selection key used for the selection. | | ||
| + | | //attributeType// | <html><p></html>"nodeProperty" (only in the case of //eventType//="attribution"), "occurrences", "repetition", or "state".<html></p></html><html><p></html>The default values are: "nodeProperty" if //eventType//="attribution", or "occurrences" if //eventType//="selection".<html></p></html> | The //attributeType// attribute identifies the variable to be evaluated in a [[assessmentstatement|<assessmentStatement>]] element. | | ||
| + | | //offset// | String. | The //offset// attribute specifies a value to be added to the selected variable before its evaluation in a [[assessmentstatement|<assessmentStatement>]] element. | | ||
