Package io.getstream.android.core.lint.detectors

Class KeepInstanceDetector

  • All Implemented Interfaces:
    com.android.tools.lint.detector.api.Detector.UastScanner , com.android.tools.lint.detector.api.FileScanner , com.android.tools.lint.detector.api.SourceCodeScanner 
    
public final class KeepInstanceDetector
extends Detector implements Detector.UastScanner

    Flags when a factory/constructor-like call that yields a type with observable or long-lived state is used inline and not kept (stored or returned).

    WRONG: SomeType(config).state.collect { ... } // call on a temporary instance SomeType(config) // created and discarded

    OK: val obj = SomeType(config); obj.state.collect { ... } return SomeType(config)

    Configure one or more interface/class FQNs via lint.xml:

    <issue id="NotKeepingInstance"> <option name="keepInstanceOf" value="com.example.SomeType, io.getstream.video.android.core.StreamClient"/> </issue>

    Matching is by assignability: the call's expression type (or resolved return type) must be the same as or a subtype/implementation of ANY listed FQN.
