class Activity

This is DSL-independent code, focusing only on run-time.

Output

signal: actual signal emitted by the task color: the mapping, where this signal will travel to. This can be e.g. Left=>:success. The polarization when building the graph.

"i am traveling towards :success because ::step said so!"

semantic: the original “semantic” or role of the signal, such as :success. This usually comes from the activity hosting this output.

Public Class Methods

End(semantic) click to toggle source

Builds an {Activity::End} instance.

# File lib/trailblazer/activity/structures.rb, line 52
def self.End(semantic)
  End.new(semantic: semantic)
end

Output(signal, semantic) click to toggle source

Builds an {Activity::Output} instance.

# File lib/trailblazer/activity/structures.rb, line 47
def self.Output(signal, semantic)
  Output.new(signal, semantic).freeze
end

Public Instance Methods

[](*key) click to toggle source

Reader and writer method for an Activity. The writer {dsl = “value”} exposes immutable behavior and will replace the old @state with a new, modified copy.

Always use the accessors to avoid leaking state to other components due to mutable write operations.

# File lib/trailblazer/activity.rb, line 23
def [](*key)
  @schema[:config][*key]
end
