Types

type Builder

type Builder interface {

	// Not makes a resulting Condition negative.
	// May be set for any resulting Condition type.
	Not() Builder

	// All defines the nested Condition set for a resulting GroupCondition with GroupLogicAnd.
	All(children []Condition) Builder

	// Any defines the nested Condition set for a resulting GroupCondition with GroupLogicOr.
	Any(children []Condition) Builder

	// Xor defines the nested Condition set for a resulting GroupCondition with GroupLogicXor.
	Xor(children []Condition) Builder

	// BuildGroupCondition builds a GroupCondition.
	BuildGroupCondition() (c Condition)

	// AttributeKey defines the incoming messages attribute key to match for a resulting KeyCondition.
	// Default is empty string key. For a TextCondition empty key causes the matching against all attribute keys.
	AttributeKey(k string) Builder

	// AnyOfWords defines the text search words (separated by a whitespace) for a resulting TextCondition.
	AnyOfWords(text string) Builder

	// TextEquals enables the exact text matching criteria for a resulting TextCondition.
	TextEquals(text string) Builder

	// BuildTextCondition builds a TextCondition.
	BuildTextCondition() (c Condition)

	// GreaterThan enables the number value matching criteria "x > val" for a NumberCondition.
	GreaterThan(val float64) Builder

	// GreaterThanOrEqual enables the number value matching criteria "x >= val" for a NumberCondition.
	GreaterThanOrEqual(val float64) Builder

	// Equal enables the number value matching criteria "x == val" for a NumberCondition.
	Equal(val float64) Builder

	// LessThanOrEqual enables the number value matching criteria "x <= val" for a NumberCondition.
	LessThanOrEqual(val float64) Builder

	// LessThan enables the number value matching criteria "x < val" for a NumberCondition.
	LessThan(val float64) Builder

	// BuildNumberCondition builds a NumberCondition
	BuildNumberCondition() (c Condition)
