class PriorityTreeNodeData

Bases: NamedTuple

PriorityTreeNodeData(result, left, middle, right, minimize)

Methods

clone([result, left, middle, right, minimize])
count(value, /)	Return number of occurrences of value.
index(value[, start, stop])	Return first index of value.
is_empty()
iter_from_right()	This is a helper function to iterate over the right-most statement of the program.
make_empty(state, middle, minimize)
short_str()

Attributes

left	Alias for field number 1
middle	Alias for field number 2
minimize	Alias for field number 4
result	Alias for field number 0
right	Alias for field number 3

__add__(value, /)

Return self+value.

__getitem__(key, /)

Return self[key].

__init__()

__iter__()

Implement iter(self).

__len__()

Return len(self).

__mul__(value, /)

Return self*value.

static __new__(_cls, result, left, middle, right, minimize)

Create new instance of PriorityTreeNodeData(result, left, middle, right, minimize)

Parameters:

• result (CrowPlanningResult3)

• left (Tuple[ScopedCrowExpression, ...])

• middle (CrowBehaviorOrderingSuite | None)

• right (Tuple[ScopedCrowExpression, ...])

• minimize (ValueOutputExpression | None)

clone(result=UNSET, left=UNSET, middle=UNSET, right=UNSET, minimize=UNSET)

Return type:

PriorityTreeNodeData

count(value, /)

Return number of occurrences of value.

index(value, start=0, stop=9223372036854775807, /)

Return first index of value.

Raises ValueError if the value is not present.

is_empty()

Return type:

bool

iter_from_right()

This is a helper function to iterate over the right-most statement of the program.

• When self.left is not empty, this function moves the left program to the right section.

  (L, M, R) <- ([], [], L) || ([], M, R)

• When self.right is not empty, this function simply pops the right-most statement and returns the new planning state.

  ([], M, [R’ | tail]) <- tail || ([], M, R’)

• When self.right is empty, this function iterates over the right-most statement of the middle program.

  ([], (M’ | tail), []) <- tail || ([], M’, [])

Return type:

Iterator[Tuple[PriorityTreeNodeData, CrowBehaviorOrderingSuite | CrowBehaviorForeachLoopSuite | CrowBehaviorWhileLoopSuite | CrowBehaviorConditionSuite | CrowBindExpression | CrowAssertExpression | CrowRuntimeAssignmentExpression | CrowControllerApplicationExpression | CrowAchieveExpression | CrowUntrackExpression | CrowBehaviorApplicationExpression | CrowBehaviorEffectApplicationExpression | CrowBehaviorCommit | MRProgram, CrowBehaviorOrderingSuite | None, int]]
