Class: OrdScheme

baja. OrdScheme


new OrdScheme()

ORD Scheme.

An ORD is made up of a series of ORD Queries separated by the '|' character.
Each ORD Query has an ORD Scheme name (e.g. 'slot') and a body (e.g.
'/Drivers/ModbusNetwork').

Methods


<static> lookup()

Return the ORD Scheme for the given scheme name.

Returns:
Type
baja.OrdScheme

equals(obj)

Indicates whether some other object is equal to this one.

Parameters:
Name Type Description
obj Object

the reference object with which to compare.

Inherited From:
Returns:

true if this object is the same as the obj argument; false otherwise.

Type
Boolean

equivalent(obj)

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.

Parameters:
Name Type Description
obj
Inherited From:
Returns:
Type
Boolean

getAgents( [is], batch)

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

Parameters:
Name Type Argument Description
is Array.<String> <optional>

An optional array of filters to add to the
agent query.

batch baja.comm.Batch

An optional object used to batch network
calls together.

Inherited From:
See:
Returns:

A promise that will resolve with the Agent Info.

Type
Promise

getIcon()

Return the Object's Icon.

Inherited From:
Returns:
Type
baja.Icon

getType()

Get the type of this instance.

Inherited From:
Returns:
Type
Type

parse()

Return an ORD Query for the scheme.

Returns:
Type
baja.OrdQuery

<abstract> resolve(target, query, cursor, options)

All extended ORD Schemes must implement this method so an ORD can be resolved!

Parameters:
Name Type Description
target module:baja/ord/OrdTarget

the current ORD Target

query baja.OrdQuery

the ORD Query used in resolving the ORD

cursor module:baja/ord/OrdQueryListCursor

the ORD Query List
cursor used for helping to asynchronously resolve the ORD

options Object

options used for resolving an ORD


toString( [cx])

Returns the String representation of this Object.

When implementing toString() on one of your own Objects, it should
adhere to the following contract.

  • When called with no arguments, it must return a string directly.
  • It can also be called with an object literal. In this case, it may
    return a Promise to be resolved with a string, or it may return a string
    directly as normal. This case is sort of analogous to
    javax.baja.sys.Localizable#toString(Context).

Therefore, when calling toString() on an Object of unknown Type using an
object literal as an argument, it's important to wrap the call in
Promise.resolve().

Parameters:
Name Type Argument Description
cx Object <optional>

optional context information to be used when
formatting the string

Inherited From:
Returns:

a string (if no context passed), or
either a string or a Promise (if context passed).

Type
String | Promise.<String>
Examples

When no context is passed, toString() must always return a string directly.

var bool = comp.get('boolean');
baja.outln(bool.toString()); // 'false'

When a context is passed, some Objects may return a Promise.

var bool = comp.get('boolean');
bool.toString({ trueText: 'Yes', falseText: 'No' })
  .then(function (str) {
    baja.outln(str); // 'No'
  });

If you don't know the type of the Object, use Promise.resolve() for safety.

var displayFacets = comp.get('displayFacets'),
    value = comp.get('value');
Promise.resolve(value.toString(displayFacets.toObject()))
  .then(function (str) {
    baja.outln(str); // formatted according to displayFacets
  });

valueOf()

Return the inner value of the object.

By default the object's instance is returned.

Inherited From:
Returns:

the inner value of the object or just the object's instance.
