Step

Implementation of a step

class DIRAC.Core.Workflow.Step.StepDefinition(step_type=None, obj=None, parent=None)

Bases: DIRAC.Core.Workflow.Parameter.AttributeCollection

__init__(step_type=None, obj=None, parent=None)

x.__init__(…) initializes x; see help(type(x)) for signature

addModule(module)
addParameter(opt, prefix='', postfix='')
addParameterLinked(opt, prefix='', postfix='')
clear() → None. Remove all items from D.
compare(s)

Custom Step comparison operation

compareParameters(s)
copy() → a shallow copy of D
createCode()

Create Step code

createModuleInstance(module_type, name)

Creates module instance of type ‘type’ with the name ‘name’

findParameter(name_or_ind)
findParameterIndex(ind)
fromkeys(S[, v]) → New dict with keys from S and values equal to v.

v defaults to None.

get(k[, d]) → D[k] if k in D, else d. d defaults to None.
getBody()
getDescrShort()
getDescription()
getName()
getOrigin()
getParent()
getRequired()
getType()
getVersion()
has_key(k) → True if D has a key k, else False
items() → list of D's (key, value) pairs, as 2-tuples
iteritems() → an iterator over the (key, value) items of D
iterkeys() → an iterator over the keys of D
itervalues() → an iterator over the values of D
keys() → list of D's keys
linkUp(opt, prefix='', postfix='', objname='self')
pop(k[, d]) → v, remove specified key and return the corresponding value.

If key is not found, d is returned if given, otherwise KeyError is raised

popitem() → (k, v), remove and return some (key, value) pair as a

2-tuple; but raise KeyError if D is empty.

removeAllParameters()
removeModuleInstance(name)

Remove module instance specified by its name

setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D
toXML()
toXMLFile(outFile)
toXMLString()
update([E, ]**F) → None. Update D from dict/iterable E and F.

If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

updateParent(parent)
values() → list of D's values
viewitems() → a set-like object providing a view on D's items
viewkeys() → a set-like object providing a view on D's keys
viewvalues() → an object providing a view on D's values
