What do "path", "type", "formatOptions", "constraints" stand for as data binding attributes

Question

I'm reading a tutorial about data binding syntax (SAPUI5). Here is an example of data binding to an oData model:

    <Input value="{
                    path: '/number',
                    type: 'sap.ui.model.type.Integer',
                    formatOptions: {
                                     minIntegerDigits: 3
                                   },
                    constraints: {
                                   maximum: 1000
                                 }
                  }"/>

So, the question is: what those "path", "type", "formatOptions", "constraints" stand for? I mean, I realize - these are some binding attributes. The value property of the Input control is a string. So, the binding attributes will be parsed and interpreted somewhere inside of the control, but they are not semantically a part of the control. So, is it some oData syntax/attributes, or what? And do you know where can I get all the possible options here?

Answer 1

Depending on the given type, different constraints and format options are possible. In your case, the type is integer/number.

Possible parameters for a general property binding are defined in the abstract class sap.ui.base.ManagedObject.

Possible constraints and format options for an Integer type are defined in the class sap.ui.model.type.Integer.

Possible format options for a number (and also for an integer) are defined in the class sap.ui.core.format.NumberFormat.
