51
52<p><a name="index-lazy-strings-in-python-2186"></a><a name="index-gdb_002eLazyString-2187"></a>
53A <dfn>lazy string</dfn> is a string whose contents is not retrieved or
54encoded until it is needed.
55
56   <p>A <code>gdb.LazyString</code> is represented in <span class="sc">gdb</span> as an
57<code>address</code> that points to a region of memory, an <code>encoding</code>
58that will be used to encode that region of memory, and a <code>length</code>
59to delimit the region of memory that represents the string.  The
60difference between a <code>gdb.LazyString</code> and a string wrapped within
61a <code>gdb.Value</code> is that a <code>gdb.LazyString</code> will be treated
62differently by <span class="sc">gdb</span> when printing.  A <code>gdb.LazyString</code> is
63retrieved and encoded during printing, while a <code>gdb.Value</code>
64wrapping a string is immediately retrieved and encoded on creation.
65
66   <p>A <code>gdb.LazyString</code> object has the following functions:
67
68<div class="defun">
69&mdash; Function: <b>LazyString.value</b> ()<var><a name="index-LazyString_002evalue-2188"></a></var><br>
70<blockquote><p>Convert the <code>gdb.LazyString</code> to a <code>gdb.Value</code>.  This value
71will point to the string in memory, but will lose all the delayed
72retrieval, encoding and handling that <span class="sc">gdb</span> applies to a
73<code>gdb.LazyString</code>. 
74</p></blockquote></div>
75
76<div class="defun">
77&mdash; Variable: <b>LazyString.address</b><var><a name="index-LazyString_002eaddress-2189"></a></var><br>
78<blockquote><p>This attribute holds the address of the string.  This attribute is not
79writable. 
80</p></blockquote></div>
81
82<div class="defun">
83&mdash; Variable: <b>LazyString.length</b><var><a name="index-LazyString_002elength-2190"></a></var><br>
84<blockquote><p>This attribute holds the length of the string in characters.  If the
85length is -1, then the string will be fetched and encoded up to the
86first null of appropriate width.  This attribute is not writable. 
87</p></blockquote></div>
88
89<div class="defun">
90&mdash; Variable: <b>LazyString.encoding</b><var><a name="index-LazyString_002eencoding-2191"></a></var><br>
91<blockquote><p>This attribute holds the encoding that will be applied to the string
92when the string is printed by <span class="sc">gdb</span>.  If the encoding is not
93set, or contains an empty string,  then <span class="sc">gdb</span> will select the
94most appropriate encoding when the string is printed.  This attribute
95is not writable. 
96</p></blockquote></div>
97
98<div class="defun">
99&mdash; Variable: <b>LazyString.type</b><var><a name="index-LazyString_002etype-2192"></a></var><br>
100<blockquote><p>This attribute holds the type that is represented by the lazy string's
101type.  For a lazy string this will always be a pointer type.  To
102resolve this to the lazy string's character type, use the type's
103<code>target</code> method.  See <a href="Types-In-Python.html#Types-In-Python">Types In Python</a>.  This attribute is not
104writable.
