Types

type ComparisonOperation

type ComparisonOperation string

const (
	Equals        ComparisonOperation = "="
	NotEquals     ComparisonOperation = "!="
	LessThan      ComparisonOperation = "<"
	LessEquals    ComparisonOperation = "<="
	GreaterEquals ComparisonOperation = ">="
	GreaterThan   ComparisonOperation = ">"
)

type Filterer

type Filterer interface {
	And(other Filterer) *LogicalExpressions
	String() string
}

Filterer interface for both Term and LogicalExpressions.

type LogicalExpression

type LogicalExpression struct {
	Op     LogicalOperation
	Filter Filterer
}

LogicalExpression represents a pair of filter terms joined with a logical operator.

type LogicalExpressions

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

LogicalExpressions represents a list of logical expressions.

func (*LogicalExpressions) And

func (le *LogicalExpressions) And(other Filterer) *LogicalExpressions

func (*LogicalExpressions) String

func (le *LogicalExpressions) String() string

type LogicalOperation

type LogicalOperation string

const (
	And LogicalOperation = "AND"
)

type Term

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

Term helps represent a single filter condition, e.g. "field = value".

func NewTerm

func NewTerm(field string, op ComparisonOperation, value interface{}) *Term

func (*Term) And

func (t *Term) And(other Filterer) *LogicalExpressions

func (*Term) String

func (t *Term) String() string
