Methods

decodeAsync(str, batchopt) → {baja.Simple|Promise.<baja.Simple>}

Description:

  • The string encoding of certain Simples may include Type information, or other data that may
    require asynchronous operations to decode. For instance, some Simples may function as
    "containers" for other Simples, and may include that Type information in the string encoding.
    That Simple would then need to import those Types before it could be fully decoded in the
    browser.

    baja.Facets is a great example of this. A Facets may contain FrozenEnum values that are
    defined by Types, such as baja:Weekday. For a Facets containing a Weekday to be fully
    constructed in the browser, the baja:Weekday Type must be imported first. Since importing
    a Type may require a network call, this Facets instance might not be able to be constructed
    synchronously, using only decodeFromString(). baja.Facets has itself implemented
    decodeAsync() to import any necessary Types.

    When implementing a Type Extension for a Simple, if your Simple references arbitrary Types that
    need to be imported when decoding your Simple, implement decodeAsync() and perform any Type
    imports (or other asynchronous operations) there.

    If you are writing code that decodes Simples from strings - that is, when you have a type spec
    and string encoding, and you need to be able to decode any kind of Simple - favor the use of
    decodeAsync, as it gives the individual Simple a chance to perform async operations to ensure
    that the decoded Simple is fully correct.

    The default implementation just returns decodeFromString directly.

    Prior to Niagara 4.14, decodeAsync() was only used in field editors. In 4.14 and later,
    decodeAsync() will be used by BajaScript itself to support asynchronous decoding of Simples
    when resolving ORDs and retrieving other data from the station.

    (Note: decodeAsync() cannot be used by the framework to decode frozen slots. If you
    have a frozen slot, whose definition is a Simple that would require the use of
    decodeAsync() to construct it, it will not work. The best approach would be to implement a
    Type Extension that would use the baja! plugin to preload all the types referenced by the
    default value of that frozen slot, so that decodeFromString would have all the information
    it needed to construct it synchronously.)

Example
return Promise.resolve(baja.$(simpleTypeSpec).decodeAsync(stringEncoding))
  .then((simpleInstance) => {});
Parameters:
Name Type Attributes Description
str string
batch baja.comm.Batch <optional>

optional batch to use
Returns:

may return the Simple instance
directly, or a Promise resolving to same - so wrap in Promise.resolve()
if unsure.

Type
baja.Simple | Promise.<baja.Simple>

decodeFromString() → {baja.PermissionsMap}

Description:

  • Decode PermissionsMap from a String.

Source:

Returns:
Type
baja.PermissionsMap

encodeToString() → {String}

Description:

  • Encode PermissionsMap to a String.

Source:

Returns:
Type
String

equals(obj) → {Boolean}

Description:

  • Equality test.

Source:

Parameters:
Name Type Description
obj
Returns:
Type
Boolean

equivalent(obj) → {Boolean}

Description:

  • Equivalence test.

    equivalent() is used to compare if two Objects have equivalent
    state, but might not want to return true for equals since it
    it has implied semantics for many operations. The default
    implementation returns the result of baja.Object#equals.

getAgents(isopt, batchopt) → {Promise}

Description:

  • Returns a promise that resolves to the agent list for this Object.

An optional array of filters to add to the
agent query.
batch baja.comm.Batch <optional>

An optional object used to batch network
calls together.

Description:

  • Return the Object's Icon.

Source:

Returns:
Type
baja.Icon

getPermissions(index) → {baja.Permissions}

Description:

  • Given a category index, return the mapped baja.Permissions
    or return baja.Permissions.none if no mapping configured.
    If this is the super user, then always return baja.Permissions.all.

    is automatically granted all permissions in all categories.

Source:

make(permissions) → {baja.PermissionsMap}

Description:

  • Make a PermissionsMap object.
    Make map where category number maps to array index.
    The first item (permissions[0]) is unused. If any
    items in the array are null, then baja.Permissions.none
    is assumed.
