Functions

func EvaluateQuery

func EvaluateQuery(env envs.Environment, query *ContactQuery, queryable Queryable) (bool, error)

EvaluateQuery evaluates the given parsed query against a queryable object

func NewErrorListener

func NewErrorListener() *errorListener

Types

type BoolCombination

type BoolCombination struct {
	// contains filtered or unexported fields
}

BoolCombination is a AND or OR combination of multiple conditions

func NewBoolCombination

func NewBoolCombination(op BoolOperator, children ...QueryNode) *BoolCombination

NewBoolCombination creates a new boolean combination

func (*BoolCombination) Children

func (b *BoolCombination) Children() []QueryNode

Children returns the children of this boolean combination

func (*BoolCombination) Evaluate

func (b *BoolCombination) Evaluate(env envs.Environment, queryable Queryable) (bool, error)

Evaluate returns whether this combination evaluates to true or false

func (*BoolCombination) Operator

func (b *BoolCombination) Operator() BoolOperator

Operator returns the type of boolean operator this combination is

func (*BoolCombination) String

func (b *BoolCombination) String() string

type BoolOperator

type BoolOperator string

BoolOperator is a boolean operator (and or or)

const (
	// BoolOperatorAnd is our constant for an AND operation
	BoolOperatorAnd BoolOperator = "and"

	// BoolOperatorOr is our constant for an OR operation
	BoolOperatorOr BoolOperator = "or"
)

type Comparator

type Comparator string

Comparator is a way of comparing two values in a condition

const (
	ComparatorEqual              Comparator = "="
	ComparatorNotEqual           Comparator = "!="
	ComparatorContains           Comparator = "~"
	ComparatorGreaterThan        Comparator = ">"
	ComparatorLessThan           Comparator = "<"
	ComparatorGreaterThanOrEqual Comparator = ">="
	ComparatorLessThanOrEqual    Comparator = "<="
)

supported comparators

type Condition

type Condition struct {
	// contains filtered or unexported fields
}

Condition represents a comparison between a keywed value on the contact and a provided value

func (*Condition) Comparator

func (c *Condition) Comparator() Comparator

Comparator returns the type of comparison being made

func (*Condition) Evaluate

func (c *Condition) Evaluate(env envs.Environment, queryable Queryable) (bool, error)

Evaluate evaluates this condition against the queryable contact

func (*Condition) PropertyKey

func (c *Condition) PropertyKey() string

PropertyKey returns the key for the property being queried

func (*Condition) PropertyType

func (c *Condition) PropertyType() PropertyType

PropertyType returns the type (attribute, scheme, field)

func (*Condition) String

func (c *Condition) String() string

func (*Condition) Validate

func (c *Condition) Validate() error

Validate checks that this condition is valid (and thus can be evaluated)

func (*Condition) Value

func (c *Condition) Value() string

Value returns the value being compared against

type ContactQuery

type ContactQuery struct {
	// contains filtered or unexported fields
}

func ParseQuery

func ParseQuery(text string, redaction envs.RedactionPolicy, fieldResolver FieldResolverFunc) (*ContactQuery, error)

ParseQuery parses a ContactQL query from the given input

func (*ContactQuery) Evaluate

func (q *ContactQuery) Evaluate(env envs.Environment, queryable Queryable) (bool, error)

func (*ContactQuery) Root

func (q *ContactQuery) Root() QueryNode

func (*ContactQuery) String

func (q *ContactQuery) String() string

type FieldResolverFunc

type FieldResolverFunc func(string) assets.Field

FieldResolverFunc resolves a query property key to a possible contact field

type PropertyType

type PropertyType string

PropertyType is the type of the lefthand side of a condition

const (
	// PropertyTypeAttribute is builtin property
	PropertyTypeAttribute PropertyType = "attribute"

	// PropertyTypeScheme is a URN scheme
	PropertyTypeScheme PropertyType = "scheme"

	// PropertyTypeField is a custom contact field
	PropertyTypeField PropertyType = "field"
)

type QueryNode

type QueryNode interface {
	fmt.Stringer
	Evaluate(envs.Environment, Queryable) (bool, error)
}

QueryNode is the base for nodes in our query parse tree

type Queryable

type Queryable interface {
	QueryProperty(envs.Environment, string, PropertyType) []interface{}
}

Queryable is the interface objects must implement queried
