Имя (Name)
babeltrace2-query-babeltrace.support-info - Babeltrace 2's
support info query object
Описание (Description)
The babeltrace.support-info Babeltrace 2 query object indicates,
for a given source component class, whether or not its instance
can handle a given input, and if so, what's the confidence of
this support.
Said input can be a simple string, an existing file path, or an
existing directory path. Components which expect some form of URI
can handle a string input, while components which expect an
existing file or directory can handle a file/directory path
input.
When the source component class's query method replies that its
component can handle a given input, it can also specify the name
of a group in which to put that input. All the inputs of a given
group, for a given component class, should be passed when
instantiating the component class as its inputs initialization
parameter (array of strings).
The babeltrace2-convert(1) command queries this object from
specific source component classes to find the most appropriate
for a given non-option argument.
Параметры (Parameters)
input=INPUT [string]
Check input INPUT.
Depending on the type parameter, this is a simple string, a
file path, or a directory path.
type=(string | file | directory) [string]
Input type, one of:
string
input parameter is a simple string.
file
input parameter is a file path.
directory
input parameter is a directory path.
It is expected that the query method does not recurse
into this directory: the result object indicates whether
or not the component class supports this specific
directory (input).
RESULT OBJECT
The result object can be one of:
• A simple real value which is the weight, between 0 and 1, of
the support by the component class for the given input.
A weight of 0 means the input is unsupported while a weight
of 1 means it's fully supported. Any value in between shows
how confident the component class is about the support of the
given input.
• A map with a weight and an optional group name.
When it's a map, the expected entries are:
group=GROUP-NAME [optional string]
Put the given input into a group named GROUP-NAME for this
component class.
If this entry is missing, then the given input gets its own,
unique group.
weight=WEIGHT [real]
Weight, between 0 and 1, of the support by the component
class for the given input.
The semantics are the same as when the result object is a
simple real value.
