IEnumerable<string> Extract()	Raises source adapter events, validates the source and calls ExtractInput().

Inherited Events

Name	Description
ETLSourceAdapterEventHandler OnSourceAdapterStart	Raised when the source adapter starts.
ETLSourceAdapterEventHandler OnExtracting	Raised before the source is extracted.
ETLSourceAdapterEventHandler OnExtracted	Raised when an input is extracted from the source.
ETLSourceAdapterEventHandler OnSourceAdapterEnd	Raised when the source adapter ends.

Remarks

The Extract() implementation performs the following:

1. If set, raises OnSourceAdapterStart.
2. If set, calls SourceValidator.Validate(SourceSpecification). Otherwise, the source is assumed valid.
3. If the source is valid:
   a. If set, raises OnExtracting.
   b. Loops through ExtractInput().
       i. If set, raises OnExtracted.
       ii. Yields the extracted input.
4. If set, raises OnSourceAdapterEnd.
