Sequence Action Handler - "shareParameters" option
shareParameters allow to share parameters across child actions instead of creating cloned version to split branches.Usage example:
# set default parameters
$parameters:
test: false
'--':
- fn: |-
parameters.test = true
- ctx:
'$.test':
inline: $ref:parameters.test
As a result of execution
ctx.test will have false value, ad -- clones parameters for each of the actions. Meaning fn function that modifies the parameters will have no affect on ctx.But, if we add
$shareParameters metadata, things will change:# set default parameters
$parameters:
test: false
'--':
# tell action to share parameters
shareParameters: true
actions:
- fn: |-
parameters.test = true
- ctx:
'$.test':
inline: $ref:parameters.test
As a result of execution
ctx.test will now have true value.Note: this is actually an anti-pattern:
parameters modification is shadowed and might not be obvious. Make sure to use shareParameters only when necessary.Last modified 4yr ago
