all_tags()

Returns a hash tagname => array of feis of all the tags set in the process instance.

all_variables()

Returns a hash fei => variable_hash containing all the variable bindings (expression by expression) of the process instance.

current_tree()

Returns the current version of the process definition tree. If no manipulation (gardening) was performed on the tree, this method yields the same result as the original_tree method.

launched_time()

Returns a Time instance indicating when the process instance was launched.

original_tree()

Returns the process definition tree as it was when this process instance was launched.

root_expression()

Returns the expression at the root of the process instance.

root_expression_for(fei)

Given an expression id, returns the root (top ancestor) for its expression.

root_expressions()

Returns a list of all the expressions that have no parent expression. The list is sorted with the deeper (closer to the original root) first.

Returns a hash tagname => fei of tags set at the root of the process instance.

variables()
