The Boolean data type represents a string.
The source value (value given in the model) must be given as boolean and is transformed into the type of the bound control property:
boolean: No transformation neededstring: "true" or "X" are interpreted as true, "false" and "" as false
The Boolean type has no format or validation constraint options.
Example how a Boolean type can be initialized:
// "TypeBoolean" required from module "sap/ui/model/type/Boolean"
// The source value is given as boolean.
var oType = new TypeBoolean();For more information, see the API Reference: sap.ui.model.type.Boolean.
