It supports a wealth of additional functions for string processing and conversion. Operators are provided so that strings can virtually be treated as a basic type.<p>An important feature of the string class, which is not present in other container classes, is that when the string contents is changed, that is resized or elements set, the string is "dereferenced", and a duplicate made of its contents. That is this instance of the array is disconnected from all other references to the string data, if any, and a new string array contents created. For example consider the following: \begin{verbatim} PString s1 = "String"; // New array allocated and set to "String" PString s2 = s1; // s2 has pointer to same array as s1 and reference count is 2 for both s1[0] = 's'; // Breaks references into different strings \end{verbatim} at the end s1 is "string" and s2 is "String" both with reference count of 1.<p>The functions that will "break" a reference are <a class="el" href="classPString.html#z235_0">SetSize()</a>#, SetMinSize()#, GetPointer()#, SetAt()# and operator[]#.<p>Note that the array is a '\0' terminated string as in C strings. Thus the memory allocated, and the length of the string may be different values.<p>Also note that the PString is inherently an 8 bit string. The character set is not defined for most operations and it may be any 8 bit character set. However when conversions are being made to or from 2 byte formats then the PString is assumed to be the UTF-8 format. The 2 byte format is nominally UCS-2 (aka BMP string) and while it is not exactly the same as UNICODE they are compatible enough for them to be treated the same for most real world usage. <p><hr><h2>Member Enumeration Documentation</h2><a name="z231_0" doxytag="PString::ConversionType"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> enum PString::ConversionType </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p><dl compact><dt><b>Enumeration values: </b></dt><dd><table border=0 cellspacing=2 cellpadding=0><tr><td valign=top><em><a name="z231_0s0" doxytag="Pascal"></a><em>Pascal</em></em> </td><td></td></tr><tr><td valign=top><em><a name="z231_0s1" doxytag="Basic"></a><em>Basic</em></em> </td><td></td></tr><tr><td valign=top><em><a name="z231_0s2" doxytag="Literal"></a><em>Literal</em></em> </td><td></td></tr><tr><td valign=top><em><a name="z231_0s3" doxytag="Signed"></a><em>Signed</em></em> </td><td></td></tr><tr><td valign=top><em><a name="z231_0s4" doxytag="Unsigned"></a><em>Unsigned</em></em> </td><td></td></tr><tr><td valign=top><em><a name="z231_0s5" doxytag="Decimal"></a><em>Decimal</em></em> </td><td></td></tr><tr><td valign=top><em><a name="z231_0s6" doxytag="Exponent"></a><em>Exponent</em></em> </td><td></td></tr><tr><td valign=top><em><a name="z231_0s7" doxytag="Printf"></a><em>Printf</em></em> </td><td></td></tr><tr><td valign=top><em><a name="z231_0s8" doxytag="NumConversionTypes"></a><em>NumConversionTypes</em></em> </td><td></td></tr></table></dl> </td> </tr></table><hr><h2>Constructor & Destructor Documentation</h2><a name="z231_1" doxytag="PString::PString"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> PINLINE PString::PString </td> <td class="md" valign="top">( </td> <td class="mdname1" valign="top" nowrap> </td> <td class="md" valign="top">) </td> <td class="md" nowrap></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Construct an empty string.
