/**
* JList, JTable and JTree are three data-rich components. They can be used to display a huge amount of data so
* searching function will be very a useful feature in those components. Searchable is such a class that
* can make JList, JTable and JTree searchable. User can simply type in any string they want to search for and use arrow
* keys to navigate to next or previous occurrence.
*
* Searchable is a base abstract class. ListSearchable, TableSearchable and
* TreeSearchable are implementations to make JList, JTable and JTree searchable respectively. For each
* implementation, there are five methods need to be implemented. protected abstract int
* getSelectedIndex() protected abstract void setSelectedIndex(int index, boolean incremental)
* protected abstract int getElementCount() protected abstract Object getElementAt(int
* index) protected abstract String convertElementToString(Object element)
*
* Please look at the javadoc of each method to learn more details.
*
* The keys used by this class are fully customizable. Subclass can override the methods such as {@link
* #isActivateKey(java.awt.event.KeyEvent)}, {@link #isDeactivateKey(java.awt.event.KeyEvent)}, {@link
* #isFindFirstKey(java.awt.event.KeyEvent)},{@link #isFindLastKey(java.awt.event.KeyEvent)}, {@link
* #isFindNextKey(java.awt.event.KeyEvent)}, {@link #isFindPreviousKey(java.awt.event.KeyEvent)} to provide its own set
* of keys.
*
* In addition to press up/down arrow to find next occurrence or previous occurrence of particular string, there are
* several other features that are very handy.
*
* Multiple selection feature - If you press CTRL key and hold it while pressing up and down arrow, it will find
* next/previous occurrence while keeping existing selections.
Select all feature - If you type in a searching text
* and press CTRL+A, all the occurrences of that searching string will be selected. This is a very handy feature. For
* example you want to delete all rows in a table whose name column begins with "old". So you can type in "old" and
* press CTRL+A, now all rows beginning with "old" will be selected. Pressing delete will delete all of them.
Basic
* regular expression support - It allows '?' to match any letter or digit, or '*' to match several letters or digits.
* Even though it's possible to implement full regular expression support, we don't want to do that. The reason is the
* regular expression is very complex, it's probably not a good idea to let user type in such a complex expression in a
* small popup window. However if your user is very familiar with regular expression, you can add the feature to
* Searchable. All you need to do is to override {@link #compare(String, String)} method and implement by
* yourself.
*
* As this is an abstract class, please refer to to javadoc of {@link ListSearchable},{@link TreeSearchable}, and {@link
* TableSearchable} to find out how to use it with JList, JTree and JTable respectively.
*
* This component has a timer. If user types very fast, it will accumulate them together and generate only one searching
* action. The timer can be controlled by {@link #setSearchingDelay(int)}.
*
* By default we will use lightweight popup for the sake of performance. But if you use heavyweight component which
* could obscure the lightweight popup, you can call {@link #setHeavyweightComponentEnabled(boolean)} to true so that
* heavyweight popup will be used.
*
* When a Searchable is installed on a component, component.getClientProperty(Searchable.CLIENT_PROPERTY_SEARCHABLE)
* will give you the Searchable instance. You can use static method {@link #getSearchable(javax.swing.JComponent)} to
* get it too.
*
* Last but not the least, only one Searchable is allowed on a component. If you install another one, it will remove the
* first one and then install the new one.
