SimpleFieldAwareEscapeAnalysis

trait SimpleFieldAwareEscapeAnalysis extends AbstractEscapeAnalysis

Very simple handling for fields and arrays. This analysis can detect global escapes via assignments to heap objects. Due to the lack of simple may-alias analysis, this analysis can not determine org.opalj.br.fpcf.properties.NoEscape states.
