A lazy string is a string whose contents is not retrieved or encoded until it is needed.
A gdb.LazyString
is represented in gdb as an
address
that points to a region of memory, an encoding
that will be used to encode that region of memory, and a length
to delimit the region of memory that represents the string. The
difference between a gdb.LazyString
and a string wrapped within
a gdb.Value
is that a gdb.LazyString
will be treated
differently by gdb when printing. A gdb.LazyString
is
retrieved and encoded during printing, while a gdb.Value
wrapping a string is immediately retrieved and encoded on creation.
A gdb.LazyString
object has the following functions:
Convert the
gdb.LazyString
to agdb.Value
. This value will point to the string in memory, but will lose all the delayed retrieval, encoding and handling that gdb applies to agdb.LazyString
.
This attribute holds the address of the string. This attribute is not writable.
This attribute holds the length of the string in characters. If the length is -1, then the string will be fetched and encoded up to the first null of appropriate width. This attribute is not writable.
This attribute holds the encoding that will be applied to the string when the string is printed by gdb. If the encoding is not set, or contains an empty string, then gdb will select the most appropriate encoding when the string is printed. This attribute is not writable.
This attribute holds the type that is represented by the lazy string's type. For a lazy string this is a pointer or array type. To resolve this to the lazy string's character type, use the type's
target
method. See Types In Python. This attribute is not writable.
