Method Detail

getInstance

public static GetManagedFieldCount getInstance(ClassEnhancer enhancer)

execute

public void execute()

Method to add the contents of the class method. Usually this method should generate bytecode as: return dnFieldNames.length + superClass.dnGetManagedFieldCount(); but due to initializing issues [ENHANCER-58], we use constants instead, e.g.: return {number of managed fields}+superClass.dnGetManagedFieldCount();
