## Detailed Description

A regmap database is a collection of regmaps or other regmap databases this allows for efficient encapsulation for multiple registers in a hierarchical fashion. A regmap_db does not manage storage for regmaps. It is simply a wrapper.

## Member Typedef Documentation

## ◆ sptr

typedef std::shared_ptr<soft_regmap_db_t> uhd::soft_regmap_db_t::sptr

## Constructor & Destructor Documentation

## ◆ soft_regmap_db_t() [1/2]

uhd::soft_regmap_db_t::soft_regmap_db_t | ( |  | ) |
| inline

Use the default constructor if this is the top-level DB

## ◆ soft_regmap_db_t() [2/2]

uhd::soft_regmap_db_t::soft_regmap_db_t | ( | const std::string & | name | ) |
| inline

Use this constructor if this is a nested DB

## Member Function Documentation

## ◆ add() [1/2]

void uhd::soft_regmap_db_t::add | ( | soft_regmap_db_t & | db | ) |
| inline

Add a level of regmap_db to this map with an identifier "name" and visibility

## ◆ add() [2/2]

void uhd::soft_regmap_db_t::add | ( | soft_regmap_t & | regmap | ) |
| inline

Add a regmap to this map with an identifier "name" and visibility

## ◆ enumerate()

std::vector< std::string > uhd::soft_regmap_db_t::enumerate | ( |  | ) | const
| inline override virtual

Enumerate the paths of all registers that this DB can access

Implements uhd::soft_regmap_accessor_t.

## ◆ get_name()

const std::string & uhd::soft_regmap_db_t::get_name | ( |  | ) | const
| inline override virtual

Get the name of this register map

Implements uhd::soft_regmap_accessor_t.

## ◆ lookup()

soft_register_base & uhd::soft_regmap_db_t::lookup | ( | const std::string & | path | ) | const
| inline override virtual

Lookup a register by path. A path is defined as a string of "/" separated tokens that scope a register. The leaf (last token) is the name of the register The token immediately before the leaf is the name of the register map If a nested regmap_db is used, the token before the regmap is the db name. For every nested db, the path has an additional token. For example: radio0/spi_regmap/spi_control_reg

Implements uhd::soft_regmap_accessor_t.
