All Implemented Interfaces:

CodeFlowAnalyzer

final class CloseableResourceAnalyzer
extends CodeFlowMap

Tracks closeable resources to detect abandoned resources (Rule 2 - E81056).
A resource is "properly managed" if it meets any of the following criteria:

• Closed via close statement (which also triggers Rule 1 error E81055)
• Escaped (returned, stored in field/collection, passed to method)
• Declared in try-with-resources (automatically managed)

This analyzer extends CodeFlowMap using the "PROPERLY_MANAGED" metadata flag to track whether a closeable resource has been properly handled before going out of scope.
