sap.ui.model.type.String

The String data type represents a string.

The source value (value given in the model) must be given as a string and is transformed into the type of the bound control property as follows:

• string: No transformation needed
• integer/float: String is parsed accordingly
• boolean: "true" or "X" are interpreted as true, "false" or " " as false

The string type does not have any format options.

Example how a String type can be initialized:

// "TypeString" required from module "sap/ui/model/type/String"

// The source value is given as string. The length of the string must not be greater than 5.
var oType = new TypeString(null, {maxLength: 5});

The String type supports the following validation constraints:

• maxLength (expects an integer number)
• minLength (expects an integer number)
• startsWith (expects a string)
• startsWithIgnoreCase (expects a string)
• endsWith (expects a string)
• endsWithIgnoreCase (expects a string)
• contains (expects a string)
• equals (expects a string)
• search (expects a regular expression)
