Function Documentation

◆ find_node()

OSSIA_EXPORT ossia::net::node_base* ossia::net::find_node ( node_base dev,
std::string_view  parameter_base 
)

Find a node in a device.

The address is in OSC format, e.g. /foo/bar.

Returns
null if the node was not found.

◆ find_nodes()

OSSIA_EXPORT std::vector<ossia::net::node_base*> ossia::net::find_nodes ( node_base dev,
std::string_view  pattern 
)

Find all nodes matching a pattern in a device.

The address is in OSC pattern match format, e.g. /foo.[0-5]/bar*

Note
If the pattern is known beforehand and may be reused, prefer storing a traversal::path and using the functions in path.hpp.

◆ create_node()

OSSIA_EXPORT node_base& ossia::net::create_node ( node_base dev,
std::string_view  parameter_base 
)

Create a node in a device.

If the node already exists, a new instance will be created. Hence there is no guarantee that the created node name is the same than the one requested; the output should be checked.

◆ create_nodes()

OSSIA_EXPORT std::vector<ossia::net::node_base*> ossia::net::create_nodes ( node_base dev,
std::string_view  pattern 
)

Create nodes according to a brace-expansion-like mechanism.

Only [] and { } are possible. e.g. /foo/{bar,baz}.[0-9][0-9].

See also
ossia::net::is_brace_expansion

◆ find_or_create_node()

OSSIA_EXPORT node_base& ossia::net::find_or_create_node ( node_base dev,
std::string_view  parameter_base 
)

Find a node and create it if it does not exist.

If the node exists, it will be returned, else a new node will be created.

◆ find_parameter_or_create_node()

OSSIA_EXPORT std::vector<parameter_base*> ossia::net::find_parameter_or_create_node ( node_base node,
std::string_view  address,
std::string_view  type 
)

Find a parameter and create it if it does not exist.

Find a node matching the address, if it already has a parameter create a new one (with name incremented by 1), if not create parameter It some matching nodes does not exist, they will be created with a parameter

Parameters
node
address
typeof the parameter
Returns
vector of created parameters

◆ list_all_children()

OSSIA_EXPORT std::vector<ossia::net::node_base*> ossia::net::list_all_children ( ossia::net::node_base node,
unsigned int  depth = 0 
)

list_all_children : list all child nodes recursively

Parameters
node: starting point
Returns
list : vector of children sorted by name then by priority

◆ to_map()

OSSIA_EXPORT ossia::value_map_type ossia::net::to_map ( const ossia::net::node_base n)
noexcept

Converts a node in a map of values.

e.g. given the tree

/foo/bar: 10
/foo/baz
/foo/baz/bux: [1.3, 5.]

then to_map(foo) gives something more or less like:

map{ { "bar", 10 }, { "baz", map{ { "bux", vector{1.3, 5} } } } }
