Types

type Comparison added in v0.1.13 

type Comparison string

Comparison is used to compare with the flow result Comparison can be string, int or bool TODO: Validation needed

type Condition 

type Condition struct {
	// Name is the name of a Condition, it's unique in a Condition group
	Name string `json:"name"`
	// Type is the data type that Tass workflow condition support
	// It also implicitly shows the result type of the flow
	// Valid values are:
	// - string: The condition type is string
	// - int: The condition type is int
	// - bool: The condition type is boolean
	Type ConditionType `json:"type"`
	// Operator defines the illegal operation in workflow condition statement
	// Valid values are:
	// - eq: The result is equal to the target
	// - ne: The result is not equal to the target
	// - lt: The result is less than the target
	// - le: The result is less than or equal to the target
	// - gt: The result is greater than the target
	// - ge: The result is greater than or equal to the target.
	Operator OperatorType `json:"operator"`
	// Target shows the specific data that the flow result uses to compare with
	// The result of the flow can be a simple type like string, bool or int
	// But it can also be a complex object contains some fileds
	// Whatever the result is, the Flow runtime will wrap the result to a JSON object
	// to unifiy the transmission process.
	// For example, the result of the user code is a string type, let's say "tass",
	// and then it will be wrapped as a JSON object {"$": "tass"} as the result of the Flow.
	//
	// If the result of user code is not a simple type, it can be much more complex
	// For example, the Flow result can be {"$":{"name": "tass","type": "faas"}}
	// So in this case, if we want to use the "type" property
	// to compare with Comparison, the Target value should be "$.type"
	//
	// If users don't specify the Target field,or the Target value is just "$",
	// it means the user code result is just a simple type
	// Otherwise, the user must provide a Target value to claim the property to use
	// One more example to show how to get the key in Flow result
	// Let's say the result is {"$":{"name":"tass","info":{"type":"fn","timeout":60}}}
	// We want the "timeout" key, so the Target value is "$.info.timeout"
	Target string `json:"target,omitempty"`
	// Comparison is used to compare with the flow result
	// Comparison can be a realistic value, like "cash", "5", "true"
	// it can also be a property of the flow result, like "$.b"
	Comparison Comparison `json:"comparison"`
	// Destination defines the downstream Flows based on the condition result
	Destination Destination `json:"destination"`
}

Condition is the control logic of the flow A sample of Condition ```yaml condition: 

 name: root
 type: int
 operator: gt
 target: $.a
 comparison: 50
 destination:
	 isTrue:  # ...
	 isFalse: # ...

``` It is same as: 

if $.a >= 50 {
	 goto isTrue logic
} else {

	 goto isFalse logic
}

func (*Condition) DeepCopy

type ConditionType 

type ConditionType string

ConditionType is the data type that Tass workflow condition support +kubebuilder:validation:Enum=string;int;bool 

const (
	// String means the condition type is string
	String ConditionType = "string"
	// Int means the condition type is int
	Int ConditionType = "int"
	// Bool means the condition type is boolean
	Bool ConditionType = "bool"
)

type Destination 

type Destination struct {
	// IsTrue defines the downstream Flows if the condition is satisfied
	// +optional
	IsTrue Next `json:"isTrue,omitempty"`
	// IsFalse defines the downstream Flows if the condition is not satisfied
	// +optional
	IsFalse Next `json:"isFalse,omitempty"`
}

Destination defines the downstream Flows based on the condition result When a Flow finishes its task, the result of the Flow goes to the downstream Flows After passing a Condition, the Flows where result goes is determinated by Destination field The result can go to the downstream Flows directly, or it needs a new round of Conditions, or both. Here is a sample of Destination: ```yaml destination: 

 isTrue:
 	 flows:
 	 - flow-a       # this is a Flow Name
	 - flow-b
 isFalse:
 	 conditions:
   - condition-a  # this is a Condition name
