TLDR

Classes

ConditionalInterceptor

This class implements the HeapAnalysisInterceptor interface and provides a way to conditionally intercept heap analysis. It takes two parameters:

• delegate: the delegate interceptor that will be run when the condition is met.
• evaluateCondition: a function that determines whether the condition is met or not, based on the HeapAnalysisJob.
