static ArrayKey | addFields (Schema &schema, std::string const &name, std::string const &doc, std::string const &unit, int size) |
Add an array of fields to a Schema, and return an ArrayKey that points to them. More... | |
A FunctorKey used to get or set a ndarray::Array from a sequence of scalar Keys.
ArrayKey operates on the convention that arrays are defined by a set of contiguous scalar fields (i.e. added to the Schema in order, with no interruption) of the same type, with a common field name prefix and "_0", "_1" etc. suffixes.

Construct from a subschema, assuming *_0, *_1, *_2, etc.
subfields
If a schema has "a_0", "a_1", and "a_2" fields, this constructor allows you to construct a 3-element ArrayKey via:
ArrayKey<T> k(schema["a"]);

Add an array of fields to a Schema, and return an ArrayKey that points to them.
[in,out] | schema | Schema to add fields to. |
[in] | name | Name prefix for all fields; "_0", "_1", etc. will be appended to this to form the full field names. |
[in] | doc | String used as the documentation for the fields. Should include a single boost::format template string, which will be substituted with the appropriate element from the docData array to form the full documentation string. |
[in] | unit | String used as the unit for all fields. |
[in] | docData | Vector of values substituted into the doc fields. The length of the vector determines the number of fields added. |
