This class implements a minor node in the libdevinfo devicetree. This is an internal class to Solaris::DeviceTree::Libdevinfo. There should be no need to generate instances of this class in an application explicitly. Instances are generated only from Solaris::DeviceTree::Libdevinfo::minor_nodes().
The following methods are available:
Return the name of the minor node. This is used e.g. as suffix of the device filename. For disks this is something like ':a' or ':a,raw'.
Return the complete physical path including the minor node
Returns the major and minor device number as a list for the node. The major numbers should be the same for all minor nodes returned by a Solaris::DeviceTree::Libdevinfo node.
Returns the nodetype of the minor node. Legal return values can be taken from <sys/sunddi.h>. With this call you can differentiate between pseudo nodes, displays and stuff.
Returns the type of the minor node. Returns raw for a raw device block for a block device
Returns true if the minor node is a raw device.
Returns true if the minor node is a block device.
Returns the associated Solaris::DevinfoTree::Libdevinfo node. One treenode can (and usually does) have multiple minor nodes.
