    193193Because the enclosing {{{Topology}}} object maintains the {{{interfaces}}} member, it is dangerous to have the same {{{Substrate}}} object in more than one {{{Topology}}}.  Use the {{{clone()}}} method to avoid this.

     195== CPU Class ==
     196
     197This represents a CPU on a computer.  It has the following members:
     198
     199 {{{type}}}::
     200  A string indicating the type of CPU.  These are not yet standardized, but common formats like "i686" or "amd64" are used.
     201 {{{attribute}}}::
     202   A list of [TopdlLibrary#AttributeClass Attribute objects] that are attached to the substrate.  The list may be empty.
     203
     204The constructor takes the member names as named parameters.
     205
     206== !OperatingSystem Class ==
     207
     208This class captures the operating system requirements of a computer.  It has the following members:
     209
     210 {{{name}}}::
     211  A string naming the operating system required.  This is usually the operating system itself, e.g., Linux, FreeBSD, Windows XP.  This may be None, indicating no preference or information.
     212 {{{version}}}::
     213  A string identifying the version of the OS.  For integrates systems like FreeBSD this is the system version.  For distribution-based systems like Linux, this is the kernel version.  See below for distribution versioning.  This may be None, indicating no version information or preference.
     214 {{{distribution}}}::
     215  A string that for operating systems that characterize OS distribution independently of kernel or base system, names the distribution in use, e.g., Ubuntu. This may be None, indicating no information or preference.
     216 {{{distributionversion}}}::
     217  A string that for operating systems that characterize OS distribution independently of kernel or base system, names the version of the distribution in use, e.g., 12.04 for Ubuntu. This may be None, indicating no information or preference.
     218
     219The constructor takes the member names as parameters.  Note that all the members may be None, but an empty {{{!OperatingSystem}}} object is not very useful.  The flexibility is there to allow specifying an operating system version without a distribution or a distribution without a base version.
     220
     221== Storage Class ==
     222
     223The storage requirements or information for a system.  This class characterizes memory or permanent storage.  Its members are:
     224
     225 {{{amount}}}::
     226  A floating point value indicating the number of megabytes of storage being considered.  Values less than 0.000001 are treated as 0.
     227 {{{persistence}}::
     228  A boolean value indicating whether this is persistent storage, such as a disk or SSD, or volitile such as memory. 
     229 {{{attribute}}}::
     230   A list of [TopdlLibrary#AttributeClass Attribute objects] that are attached to the machine.  The list may be empty.
     231
     232Currently there is no field for media type.  Use attributes.
     233
     234The constructor takes the member names as named parameters.
     235
     236== Software Class ==
     237
     238This indicates what software must be installed on a system.  Its members are:
     239
     240 {{{location}}}::
     241  A string containing a URI from which to install the software, e.g., a file: URI pointing to a tarfile.
     242 {{{install}}}::
     243   A string containing location in the local file system to base the software install.  This may be None, indicating that the software distribution format includes this information, e.g., an rpm or debian software file.
     244
     245The constructor takes the member names as named parameters.
