Class: CountedList

CountedList(objs, source)

Generic list-ish class for NamedTootCount objects with name and numToots properties. Supports both dictionary and sorted list operations and provides utility methods for filtering, mapping, counting, and muting/removing items by keywords or server-side filters.

Constructor

new CountedList(objs, source)

Parameters:
Name Type Description
objs Array of objects to initialize the list with.
source CountedListSource Source of the list (for logging/context).
Properties:
Name Type Description
length number The number of objects in the list.
logger Logger Logger instance for this list.
maxNumToots number | undefined Current maximum numToots value in the list.
nameDict Record.<string, T> Dictionary mapping object names to objects.
objs Array.<T> The array of objects in the list.
source ListSource The source of the list (for logging/context).

Members

objs

Has side effect of mutating the CountedList.nameDict property.

Methods

addObjs(objs)

Add objects we don't already have. This does NOT set the numToots property on incoming objs!
Parameters:
Name Type Description
objs Array.<T> Array of objects to add to the list.

filter(predicate) → {module:api/counted_list~CountedList.<T>}

Like the standard javascript Array.filter().
Parameters:
Name Type Description
predicate function Function to test each object in the list.
Returns:
A new CountedList containing only the objects that match the predicate.
Type
module:api/counted_list~CountedList.<T>

forEach()

Standard Array.forEach() approximation that invokes a callback for each object in the objs array.

getObj(name) → {T|undefined}

Returns the object in the list with the given name (case-insensitive) if it exists.
Parameters:
Name Type Description
name string The name of the object to retrieve.
Returns:
The object with the specified name, or undefined if not found.
Type
T | undefined

incrementCount(name, newObjDecoratoropt) → {T}

Increment numToots for the given name. If no obj with name exists create a new one and call newObjDecorator() to fill in its properties.
Parameters:
Name Type Attributes Description
name string The name of the object to increment.
newObjDecorator function <optional>
 Optional function to decorate the new object with additional properties.
Returns:
The object with the incremented numToots.
Type
T

map()

Standard map function that applies a callback to each object in this.objs.

maxValue(propertyName) → {number|undefined}

Get the maximum value for a given property across the this.objs array.
Parameters:
Name Type Description
propertyName
Returns:
The maximum value for the specified property, or undefined if none exist.
Type
number | undefined

nameToNumTootsDict() → {StringNumberDict}

Returns a dict of obj.name to obj.numToots.
Returns:
Dictionary mapping object names to their numToots counts.
Type
StringNumberDict

populateByCountingProps(objs, propExtractor)

Populate the objs array by counting the number of times each 'name' (given by propExtractor) appears. Resulting BooleanFilterOptions will be decorated with properties returned by propExtractor().
Parameters:
Name Type Description
objs Array.<U> Array of objects to count properties from.
propExtractor function Function to extract the decorator properties for the counted objects.

removeKeywords(keywords)

Remove any obj whose name matches any of the keywords.
Parameters:
Name Type Description
keywords Array.<string> Array of keywords to match against the object's name.

topObjs(maxObjsopt) → {Array.<T>}

Returns the objs in the list sorted by numAccounts if it exists, otherwise by numToots, and then by name. If maxObjs is provided, returns only the top maxObjs objects.
Parameters:
Name Type Attributes Description
maxObjs number <optional>
 Optional maximum number of objects to return.
Returns:
Objects sorted by numAccounts if it exists, otherwise numToots, then by name
Type
Array.<T>
