 public  void finish() 
{
        this.pageContext = null;
        this.decoratedObject = null;
}

Called at the end of evaluation to clean up instance variable. A subclass of Decorator can override this method but should always call super.finish() before return

 public Object getDecoratedObject() 
{
        return this.decoratedObject;
}

returns the decorated object.

 public PageContext getPageContext() 
{
        return this.pageContext;
}

returns the page context.

 public boolean hasGetterFor(String propertyName) 
{
        String simpleProperty = propertyName;
        // get the simple (not nested) bean property
        int indexOfDot = simpleProperty.indexOf('.");
        if (indexOfDot  > 0)
        {
            simpleProperty = simpleProperty.substring(0, indexOfDot);
        }
        Boolean cachedResult = (Boolean) propertyMap.get(getClass().getName()
            + CLASS_PROPERTY_SEPARATOR
            + simpleProperty);
        if (cachedResult != null)
        {
            return cachedResult.booleanValue();
        }
        // not already cached... check
        boolean hasGetter = searchGetterFor(propertyName);
        // save in cache
        propertyMap.put(getClass().getName() + CLASS_PROPERTY_SEPARATOR + simpleProperty, BooleanUtils
            .toBooleanObject(hasGetter));
        // and return
        return hasGetter;
}

Check if a getter exists for a given property. Uses cached info if property has already been requested. This method only check for a simple property, if pPropertyName contains multiple tokens only the first part is evaluated

 public  void init(PageContext pageContext,
    Object decorated) 
{
                                
        this.pageContext = pageContext;
        this.decoratedObject = decorated;
}

Initialize the TableTecorator instance.

 public  void init(PageContext pageContext,
    Object decorated,
    TableModel tableModel) 
{
        // temporary used for backward (source) compatibility
        init(pageContext, decorated);
        this.tableModel = tableModel;
}

Initialize the TableTecorator instance.

 public boolean searchGetterFor(String propertyName) 
{
        Class type = null;
        try
        {
            // using getPropertyType instead of isReadable since isReadable doesn't support mapped properties.
            // Note that this method usually returns null if a property is not found and doesn't throw any exception
            // also for non existent properties
            type = PropertyUtils.getPropertyType(this, propertyName);
        }
        catch (IllegalAccessException e)
        {
            // ignore
        }
        catch (InvocationTargetException e)
        {
            // ignore
        }
        catch (NoSuchMethodException e)
        {
            // ignore
        }
        return type != null;
}

Looks for a getter for the given property using introspection.
