public boolean hasStaticFieldRead ( String owner , String methodName , String targetClass , String targetField ) { StaticFieldReadEntry read = new StaticFieldReadEntry ( owner , methodName , targetClass , targetField ) ; return staticFieldReads . contains ( read ) ; }
returns if there is a static field read egde ( getstatic bytecode instruction ) from < owner , methodname > to < targetclass , targetfield > .
