Where does DisposableBase live in the IronOCR API?

DisposableBase is an abstract class in the DynamicTesseract namespace, shipped in IronOcr.dll. It derives from Object and implements IDisposable, serving as the base for disposable interop types such as ChoiceIterator.

What derives from DisposableBase in IronOCR?

Interop wrappers that hold a native handle derive from it; ChoiceIterator is one such subclass. Each subclass overrides the protected Dispose(Boolean) method to release its own resource, and callers dispose the object through Dispose or a using statement.

Syntax

public abstract class DisposableBase : Object

Deterministic cleanup of native OCR handles is what DisposableBase standardizes across the DynamicTesseract interop layer. Many of those interop types wrap an unmanaged Tesseract or Leptonica resource that must be released promptly, and this abstract base gives them one correct, shared implementation of the dispose pattern instead of each type reinventing it.

A developer rarely names DisposableBase directly; it is the parent that interop wrappers such as ChoiceIterator derive from. What matters when working with any of those subclasses is the contract it defines: IsDisposed reports whether the native resource has already been freed, Dispose releases it, and VerifyNotDisposed guards a member so a call after disposal fails clearly rather than touching a freed handle. The protected Dispose(Boolean) overload is the override point a subclass implements to free its specific handle, and Finalize is the safety net if Dispose is never called. The practical rule is the usual one: dispose any DynamicTesseract object that derives from this base, ideally with a using statement, so native memory is reclaimed at once.

Disposal and lifecycle matter most under load, which the async OCR how-to addresses, and the advanced reading configuration how-to covers deeper engine control.
