MAXON_INTERFACE_NONVIRTUAL()

MAXON_INTERFACE_NONVIRTUAL ( GraphLib  , MAXON_REFERENCE_STATIC  , "net.maxon.graph.interface.graphlib"  , MAXON_IMPLEMENTATION_MODULE("net.maxon.nodes")    )

private

CreateAttribute()

static MAXON_METHOD Result<GraphAttribute> CreateAttribute ( const InternedId &  attr, GraphAttributeInterface::FLAGS  flags  )

static

Creates a GraphAttribute with the given name and flags

Parameters

[in]	attr	The name of the attribute.
[in]	flags	The flags of the attribute.

Returns

A new GraphAttribute with the given name and flags.

CreateMessage()

static MAXON_METHOD Result<GraphMessage> CreateMessage ( GraphAttributeInterface::FLAGS  flags, const NodePath &  origin, const ConstDataPtr &  value  )

static

Creates a GraphMessage.

Parameters

[in]	flags	The flags of the message.
[in]	origin	The origin of the message.
[in]	value	The ToString function of value will be called to implement GraphMessageInterface::Format.

Returns

A new GraphMessage for the given parameters.

CreateSimpleGraphModel()

static MAXON_METHOD Result<GraphModelRef> CreateSimpleGraphModel ( )

static

Creates a new instance of a simple implementation of GraphModelInterface. The simple graph model only manages plain nodes, ports and connections, but it doesn't support advanced features like inheritance from base graphs, derived attributes, implicit connections, rollback of transactions or change lists.

Returns

A new GraphModelRef which uses a simple implementation of GraphModelInterface.

WriteGml()

static MAXON_METHOD Result<void> WriteGml ( const GraphModelRef &  graph, UrlOrOutputStream &&  output  )

static

Writes a graph to a GML file (Graph Modeling Language).

Parameters

[in]	graph	The graph to write.
[in]	output	The output stream to write to.

CreatePathFormatter()

static MAXON_METHOD ErrorInterface::PartFormatter CreatePathFormatter ( const GraphModelRef &  graph )

static

Returns a PartFormatter which formats NodePath and GraphNode parts using their effective names. Also DataType parts are formatted with the help of DataTypeBuilderInterface::GetDataTypeName.

Parameters

[in]

graph

The graph to use for name lookup.

Returns

A PartFormatter which can be used to format node-related error messages.

ExtractNodePath()

static MAXON_METHOD Result<NodePath> ExtractNodePath ( const String &  message )

static

Extracts a node path from the given message. If the message was formatted by the formatter created by CreatePathFormatter, this function will find the first occurrence of a formatted node path and return its original NodePath. Otherwise it will return an empty node path (unless the message happens to contain a substring which matches a formatted node path).

Parameters

[in]

message

An error message created by CreatePathFormatter.

Returns

The NodePath of the first path contained in the message, or an empty path if no path can be found.
