Object initialization, setting all the default values.
Optional newData: anythe data to load, optional
Optional options: anycustom options to apply; they will depend on the child resource
Usually, there is no need to implement the constructor; implicitly, it will call the load of the child resource
and therefore loading all the resources with default values.
If needed, this is the suggested implementation:
super();
this.load(x);
// ...
A Label (markdown support) that may contain variables to subsitute (e.g. Here's **@myVar**).
Note: the variable substitution is made on runtime data, based on the section's context.
Return an attribute in a cleaned standard that force-cast the element.
the origin attribute, to cast
the cast function, e.g. Boolean, Number, String, x => new CustomClass(x), etc.
Optional defaultVal: anyif set, the fallback value instead of null
cleaned attribute
Return an array in a cleaned standard that force-cast each element, keeping only the valid ones.
the origin array, to cast and check
the cast function, e.g. x => String(x) or x => new CustomClass(x)
Optional defaultVal: anyif set, the fallback value instead of null
cleaned array
Shortcut to Utils.isEmpty to check the emptiness of a field.
Optional type: isEmptyFieldTypesLoad the attributes from an already existing resource.
the data to load
custom options to apply; they will depend on the child resource
Typical implementation:
super.load(newData);
this.attr = this.clean(newData.attr, String);
this.attr2 = this.clean(newData.attr2, Number, 0);
this.attr3 = this.clean(newData.attr3, a => new Date(a), Date.now());
this.arr = this.cleanArray(arr, String);
// ...
Load the attributes from an already existing resource and then force some attributes to assume safeData values. The function is usually used in the back-end to mix together db data with new data, without the risk of changing ids and other attributes which are managed in appositely curated scenario.
the data to load
the attributes to force to specific values
Optional options: anycustom options to apply; they will depend on the child resource
Typical implementation:
super.safeLoad(newData, safeData);
this.keyAttr = safeData.keyAttr;
this.importantAttr = safeData.importantAttr;
this.isDraft = safeData.isDraft;
// ...
Note well: there is no need to call this.load(), since it's implicitly called from super.safeLoad(),
which will anyway use the child version of the method.
Valide the object's attributes, performing all the checkings.
Optional options: anycustom options to apply; they will depend on the implementations
errors if empty, the checkings are successfully passed.
Typical implementation:
const e = super.validate();
if(this.iE(this.attr)) e.push(`attr`);
// ...
return e;
