TaskBatchBase<T extends Object> class abstract

Provides a foundational structure for managing a collection of tasks.

This class handles queue management and provides guards to prevent unsafe modifications. Subclasses are responsible for implementing the execution strategy (e.g., sequential or concurrent).

Constructors

TaskBatchBase.new()

Properties

executionCount → int
The total number of tasks to be executed in the current batch.
no setter
executionIndex → int
The index of the currently executing task. Zero-based.
no setter
executionProgress → double
The execution progress as a value between 0.0 and 1.0. Returns 0.0 if executionCount is zero.
no setter
hashCode → int
The hash code for this object.
no setterinherited
isExecuting → bool
Indicates if the batch is actively processing tasks.
no setter

clearTasks() → bool
Clears all tasks from the queue.
executeTasks() → TResolvableOption<T>
Defines the task execution strategy for the batch.
noSuchMethod(Invocation invocation) → dynamic

inherited
removeFirstTask() → bool
Removes the first task from the queue.
removeLastTask() → bool
Removes the last task from the queue.
removeTask(Task<T> task) → bool
Removes a specific task from the queue.
