NXgraph_node_set¶
Status:
base class, extends NXobject
Description:
A set of nodes/vertices in space representing members of a graph.
Symbols:
The symbols used in the schema to specify e.g. dimensions of arrays.
d: The dimensionality of the graph. Eventually use one for categorical.
c: The cardinality of the set, i.e. the number of nodes/vertices of the graph.
- Groups cited:
none
Structure:
dimensionality: (optional) NX_POSINT {units=NX_UNITLESS}
cardinality: (optional) NX_POSINT {units=NX_UNITLESS}
identifier_offset: (optional) NX_INT {units=NX_UNITLESS}
Integer which specifies the first index to be used for distinguishing nodes. Identifiers are defined either implicitly or explicitly. For implicit indexing the identifiers are defined on the interval [identifier_offset, identifier_offset+c-1]. For explicit indexing the identifier array has to be defined.
The identifier_offset field can for example be used to communicate if the identifiers are expected to start from 1 (referred to as Fortran-/Matlab-) or from 0 (referred to as C-, Python-style index notation) respectively.
identifier: (optional) NX_INT (Rank: 1, Dimensions: [c]) {units=NX_UNITLESS}
Integer used to distinguish nodes for explicit indexing.
is_a: (optional) NX_CHAR (Rank: 1, Dimensions: [c])
A human-readable qualifier which type or e.g. class instance the node is an instance of. As e.g. a NeXus application definition is a graph, more specifically a hierarchical directed labelled property graph, instances which are groups like NXgraph_node_set could have an is_a qualifier reading NXgraph_node_set.
label: (optional) NX_CHAR (Rank: 1, Dimensions: [c])
A human-readable label/caption/tag of the graph.
