Beginning in version 1.3 of Infusion, these Framework Functions will be documented in our new Documentation space. This migration is currently in progress, and will be complete in time for the 1.3 release. At that time, this page will be deprecated in favor of the new pages.

If you have any comments on the new documentation format, feel free to let us know by emailing the infusion-users mailing list.

The Fluid framework includes a number of functions and utilities that component developers can avail themselves of. These are described below.

fluid.js

NEW DOCUMENTATION: Please visit our new documentation space for updated documentation on fluid.accumulate

fluid.accumulate(list, fn, arg)


Description

Scans through a list of objects, "accumulating" a value over them (may be a straightforward "sum" or some other chained computation). The results will be added to the initial value passed in by "arg" and returned.

To a Google developer, this would be "reduce", from the "map/reduce" pairing.

Arguments

  • list {Array}: The list of objects to be accumulated over
  • fn {Function}: An "accumulation function" accepting the signature (object, total, index) where object is the list member, total is the "running total" object (which is the return value form the previous function), and index is the index number.
  • arg {Object}: The initial value for the "running total" object

Return Value

Object: the modified "arg" object

New in v1.3: fluid.allocateGuid()


Please see fluid.allocateGuid in the new Documentation space.

Return Value

String: representing the id

New in v1.3: fluid.arrayToHash()


Please see fluid.arrayToHash in the new Documentation space.


NEW DOCUMENTATION: Please visit our new documentation space for updated documentation on fluid.byId

fluid.byId(id, dokkument)

Return Value

No Return Value

fluid.COMPONENT_OPTIONS


Description

A special "marker object" which is recognized as one of the arguments to fluid:fluid.initSubComponents. This object is recognized by reference equality - where it is found, it is replaced in the actual argument position supplied to the specific subcomponent instance, with the particular options block for that instance attached to the overall "that" object.

In essence, it tells fluid.initSubComponents to look at the parent component's options block. If options were specified for this subComponent, they will be merged in for use by that subcomponent.

Constant Value

Constant: {}

fluid.initSubcomponent(that, className, args)


Description

Provides a generic way of instantiating and configuring any "subcomponents" that may be a part of, or used by, a parent component. For example, this function is used by the Inline Edit component to instantiate the Undo decorator, a subcomponent that provides Undo functionality to components that support it.

Arguments

  • that {Component}: The top-level component for which subcomponents are to be instantiated. It contains specifications for these subcomponents in its options structure.
  • className {String}: The "class name" or "category" for the subcomponents to be instantiated. A class name specifies an overall "function" for a class of subcomponents and represents a category which accept the name signature of instantiation arguments.
  • args {Array of Object}: The instantiation arguments to be passed to each constructed subcomponent. These will typically be members derived from the top-level "that" or perhaps globally discovered from elsewhere. One of these arguments may be fluid.COMPONENT_OPTIONS in which case this placeholder argument will be replaced by instance specific options configured into the member of the top-level options structure named for the className.

Return Value

Component: a single component

Reference

See: Subcomponents, fluid:fluid.initSubcomponents

fluid.initSubcomponents(that, className, args)


Description

Initialize all the "subcomponents" which are configured to be attached to the supplied top-level component, which share a particular "class name".

  • className {String}: The "class name" or "category" for the sub-components to be instantiated. A class name specifies an overall "function" for a class of sub-components and represents a category which accept the name signature of instantiation arguments.
  • args {Array of Object}: The instantiation arguments to be passed to each constructed sub-component. These will typically be members derived from the top-level "that" or perhaps globally discovered from elsewhere. One of theses arguments may be fluid.COMPONENT_OPTIONS in which case this placeholder argument will be replaced by instance specific options configured into the member of the top-level options structure named for the className.

Return Value

Array: of sub-components

Reference

See also: fluid:fluid.COMPONENT_OPTIONS, fluid:fluid.initSubcomponent

  • container {jQueryable}: A specifier for the single root "container node" in the DOM which will house all the markup for this component. Can be an element, selector, function that returns an element, or a jQuery.
  • userOptions {Object}: The configuration options for this component.

Return Value

Component: the initialized component

fluid.instantiateFirers(that, options)

  2. A unicast event, which allows only one listener to be registered
  3. A preventable event.

Arguments

  • that {Object}: The component
  • options {Object}: The component's options structure, containing the declared event names and types.

Return Value

No Return Value

  • args {Array}: An array of arguments to be applied to the function, specified in functionPath
  • environment {Object}: (optional) A hash of root path segments to objects that can be used to override lookups to the global object. This would typically be used by the Fluid framework itself to direct lookups to the correct version of the root fluid object.
