Interface Condition

All Superinterfaces:

Iterable<ConditionLeaf>

All Known Subinterfaces:

ConditionLeaf

public interface Condition
extends Iterable<ConditionLeaf>

Represents a condition or a set of conditions for workflow transition.

Condition may be one of three types:

• a conjunction of conditions
• an alternative of conditions
• a leaf that evaluates to true/false

If it's one of the first two types, then you can get the children conditions by calling the getChildren() method.

If it's a leaf, then you can get it using toLeaf() method

The Condition implements Iterable<ClassCondition> so that you can easily inspect all the leaves if you only care about the conditions leaves in separation from the expression structure. The order of iteration is undefined.

Method Detail

getType

Condition.Type getType()

Returns this condition type. Use this method to determine which method to use next: getChildren() or toLeaf().

Returns:

this condition type.

getChildren

io.atlassian.fugue.Maybe<List<Condition>> getChildren()

Returns a list of sub-conditions if this condition is of type Condition.Type.CONJUNCTION or Condition.Type.ALTERNATIVE, otherwise none.

The returned list is immutable.

Returns:

a list of children if this object is not a leaf, otherwise none.

toLeaf

io.atlassian.fugue.Maybe<ConditionLeaf> toLeaf()

Returns itself if this object is a leaf, otherwise none.

Returns:

itself if this object is a leaf, otherwise none.
