== Description ==&lt;br /&gt;
This method is guaranteed to preserve the current data in the&lt;br /&gt;
buffer. If you need only to write to the buffer, use the&lt;br /&gt;
Write method. Use this method when you need read and write&lt;br /&gt;
access to the data for writing. If you just need to read the&lt;br /&gt;
data, use Read instead! Read is faster, as Modify may result&lt;br /&gt;
in additional memory allocation and copy operations if the&lt;br /&gt;
internal data buffer is shared. Write is faster than the&lt;br /&gt;
Modify method, as it will not perform any copies of the&lt;br /&gt;
existing data.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Example:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;code&amp;gt;&lt;br /&gt;
 var RawData : PByte;&lt;br /&gt;
 &lt;br /&gt;
 RawData := BlockBuffer.Modify();&lt;br /&gt;
&amp;lt;/code&amp;gt;&lt;/div&gt;</summary>
