The Abstract Syntax Tree represents the structure of source input files.
→ Program Structure Interface

Provides semantic highlighting based on underlying → Program Structure Interface elements.
→ Inspection

Executing in the Blocking Context means executing tasks on a thread without access to a coroutine context.
→ Suspending Context
→ Coroutine Execution Context
→ Coroutine

java.util.concurrent.CancellationException, kotlin.coroutines.cancellation.CancellationException (typealias in stdlib), kotlinx.coroutines.CancellationException (typealias in kotlinx-coroutines)
→ ProcessCanceledException

A Kotlin coroutines execution unit allowing for handling concurrency and asynchronous tasks efficiently with a sequential/imperative code style.

Part of the coroutine context. Determines a thread or a thread pool the corresponding coroutine is executed on. See Coroutine Dispatchers for more details.
→ Coroutine

Executing in the Coroutine Execution Context means executing code (suspending or non-suspending/blocking) from a coroutine.

Coroutine scopes define the lifetime of coroutines and ensure proper handling of coroutine cancellations and structured concurrency.
→ Coroutine

XML DOM API abstracts working with XML files based on a custom semantic model.

The Event Dispatch Thread handles all Swing events. See also Threading Model and EDT Dispatcher.

Most functionality is provided by Using Extension Points provided by the platform or plugins. Plugins can also define their own to allow extensibility.

External System Integration allows integrating external project management systems.

JetBrains internal API to track feature usage in the IDE.

File Based Index allows storing key-value information based on the project's files.

A configuration file written in Kotlin (build.gradle.kts) or Groovy (build.gradle) that describes the build process and dependencies of a plugin.

Supports configurable semantic highlighting.
→ Annotator

Provides an automated fix for commonly encountered code problems.

Communication standard between development tools and Language Servers, see Language Server Protocol (LSP).

A builtin → Version Control System tracking all changes in the project locally.

Defines the visual appearance and behavior of the user interface; see Swing Tutorial.

Represents the project model in External Build process.

The JetBrains Runtime is the default bundled runtime for all IntelliJ Platform-based IDEs by JetBrains.

A → Read Action that is canceled by a → Write Action. See also Read Action Cancellability.

ProcessCanceledException An exception indicating that the currently running operation was terminated and should finish as soon as possible.
→ CancellationException

The Program Structure Interface represents a syntactic and semantic code model of the source input files.
→ Abstract Syntax Tree → Stubs

Allows accessing code-related data structures for reading purposes. See also Threading Model.
→ Non-Blocking Read Action → Write Action

A Run Configuration allows running external processes from within the IDE.

Allows searching and replacing code by defining the structure of the searched code fragments, see Structural Search and Replace Inspections.

A subset of a → Program Structure Interface tree in a binary serialized compact format, see Stub Indexes.

Executing in the Suspending Context means executing tasks in Kotlin coroutines.
→ Blocking Context
→ Coroutine Execution Context
→ Coroutine

A semantic element in some model, e.g., language or framework model, see Symbols.

An abstraction layer on the → Program Structure Interface of different JVM languages.

The API for Version Control System allows accessing builtin as well as adding custom implementations.

A Virtual File represents a file in a → Virtual File System.

A Virtual File System provides a unified API for working with files represented as → Virtual File.

Allows accessing code-related data structures for writing purposes. See also Threading Model.
→ Read Action

A coroutine → Read Action that is canceled by an incoming → Write Action. See Coroutine Read Actions API for details.
→ Suspending Context
→ Coroutine

A coroutine → Read Action that blocks incoming → Write Action. See Coroutine Read Actions API for details.
