<module name="IntegerList">
<short>
Provides lists for Integer data types implemented using generics.
</short>
<descr>
<p>
<file>integerlist.pas</file> contains a list for Integer values implemented 
using generics, and provides the same methods and properties for 
<var>Integer</var> types as provided for <var>String</var> types in 
<var>TStringList</var>. Specializations are provided for the Byte, Word, 
Cardinal, Integer, and Int64 types. Each provides an overloaded 
<var>Sort</var> method to ensure that the type for the specialization is 
handled in the method.
</p>
<p>
<file>integerlist.pas</file> is part of the <file>LazUtils</file> package.
</p>
</descr>

<element name="TByteList">
<short>Implements a specialization of TFPGList for the Byte data type.</short>
<descr>
<p>
<var>TByteList</var> provides an overloaded <var>Sort</var> method to ensure 
that values in the list are handled using a compare function that operates on 
Byte values. Internally, it provides a TFPGListEnumerator which is 
specialized for the Byte type used in the implementation.
</p>
<p>
Use the properties and methods defined in the ancestor class to perform 
common operations for Byte values, including:
</p>
<ul>
<li>Add</li>
<li>IndexOf</li>
<li>Insert</li>
<li>Extract</li>
<li>Remove</li>
<li>Sort</li>
<li>AddList</li>
<li>Assign</li>
<li>First</li>
<li>Last</li>
<li>Items</li>
<li>List</li>
</ul>
<p>
Items is the default property, and allows access to values by ordinal 
position or by using an enumerator to traverse the Byte values in List.

<var>TWordList</var> provides an overloaded <var>Sort</var> method to ensure 
that values in the list are handled using a compare function that operates on 
Word values. Internally, it provides a TFPGListEnumerator which is 
specialized for the Word type used in the implementation.
