Xref
|
This class represents an xref database. An
XrefGraph object represents the relationship between a host
drawing, its externally referenced drawings, and any nested xref
drawings. Within a graph, any database or xref BlockTableRecord is
represented by the XrefGraphNode class. Relationships between
databases are represented by an edge in the graph. These
relationships can be input (databases that are referencing this
node) and output (databases that are referenced by this node). The
relationships can be obtained using the GraphNode.in(idx) and
GraphNode.out(idx) calls.

Methods
| Name | Description | |
|---|---|---|
|
AddRefTo | Creates an outgoing reference, in this GraphNode object, to the
specified GraphNode object. (Inherited from GraphNode) |
|
|
Clear | Clears the specified set flag bits in this GraphNode
object. (Inherited from GraphNode) |
|
|
CreateObjRef | (Inherited from MarshalByRefObject) |
|
|
CycleIn | Returns the specified incoming cyclical reference of this
GraphNode object. (Inherited from GraphNode) |
|
|
CycleOut | Returns the specified outgoing cyclical reference of this
GraphNode object. (Inherited from GraphNode) |
|
DeleteUnmanagedObject | (Inherited from GraphNode) |
|
|
DisconnectAll | Removes all references in and to this GraphNode object. (Inherited from GraphNode) |
|
|
Dispose | (Inherited from DisposableWrapper) |
|
|
Dispose(Boolean) | (Inherited from DisposableWrapper) |
|
|
Equals | Checks objects for equality. (Inherited from DisposableWrapper) |
|
|
Finalize | (Inherited from DisposableWrapper) |
|
|
GetHashCode | Retrieves the object hash code. (Inherited from DisposableWrapper) |
|
|
GetLifetimeService | (Inherited from MarshalByRefObject) |
|
|
GetType | (Inherited from Object) |
|
|
In | Returns the specified incoming reference of this GraphNode
object. (Inherited from GraphNode) |
|
|
InitializeLifetimeService | (Inherited from MarshalByRefObject) |
|
|
IsMarkedAs | Checks whether all the specified set flag bits are set in this
GraphNode object. (Inherited from GraphNode) |
|
|
MarkAs | Sets the specified flag bits set in this GraphNode
object. (Inherited from GraphNode) |
|
|
MarkTree | Marks this GraphNode object and all nested outgoing GraphNode
objects with the specified flags. (Inherited from GraphNode) |
|
|
MemberwiseClone | (Inherited from Object) |
|
|
MemberwiseClone(Boolean) | (Inherited from MarshalByRefObject) |
|
|
Out | Returns the specified outgoing reference of this GraphNode
object. (Inherited from GraphNode) |
|
|
RemoveRefTo | Removes the outgoing reference, in this GraphNode object, to
the specified GraphNode object. (Inherited from GraphNode) |
|
|
SetEdgeGrowthRate | Sets the number of outgoing and incoming edges that are
allocated at a time on a graph node. If the node-to-node
relationship contains many edges, this method should be called to
increase the rate of the outgoing and incoming edges from the
defaults of 4 and 2 respectively. Setting the rates to higher
values increases performance but may increase memory usage. (Inherited from GraphNode) |
