Outliers with High or Low Essence

This page presents classes in our corpus with the highest or lowest relative essence. Note that 125640 classes (59%) have zero relative essence. Thus, we only report two small samples of those zero-essence classes. The first sample consists of those zero-essence classes containing the largest number of methods (zero essence, but lots of loop call graph nodes). The second sample constitutes a random sample of zero-essence classes (thus, it is not biased in any way).

High Relative Essence (Classes with Highest Relative Essence)

The classes mostly contain long methods, sometimes accompanied by comments.

Zero Relative Essence (Classes with Largest Number of Methods)

The classes are mostly data classes, middle men, or adapters with default method implementations, or they are machine-generated.

Package Class Methods Comment/Smell/Pattern
net.sf.jasperreports.engine.util. JRStyleResolver 99 all static "decorator" methods, all following almost the same code pattern (if delegate returns null, ask someone else)
org.apache.openejb.jee.oejb2. ObjectFactory 99 (non-abstract) factory
org.jruby.ast.visitor. AbstractVisitor 97 abstract superclass for visitor implementations, provides a large number of default visit methods
org.apache.poi.hssf.record. ExtendedFormatRecord 96 data class that can serialize/deserialize its objects to/from binary representation
org.hibernate.cfg. Settings 95 data class
sandmark.util.newgraph. EditableGraphStyle 94 middle man (acts as a kind of facade on or adapter to NodeAttributes and EdgeAttributes)
com.ibm.as400.vaccess. AS400JDBCDataSourcePaneDataBean 94 data class (a "DataBean", used by GUI to load/store its state)
org.compiere.model. X_M_InOut 94 not human-written, but machine-generated code
org.compiere.model. X_M_Product 94 not human-written, but machine-generated code
