Types

type MultiTag

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

MultiTag is a structure to efficiently query a struct field' tags, regardless of their complexity.

func GetFieldTag

func GetFieldTag(field reflect.StructField) (MultiTag, bool, error)

GetFieldTag directly reads, creates and parses a struct field and returns either a working multiTag, or an error if parsing failed.

func NewMultiTag

func NewMultiTag(v string) MultiTag

NewMultiTag returns a new multi tag from a field tag string. The tags have not been parsed, you must call tag.Parse().

func (*MultiTag) Get

func (x *MultiTag) Get(key string) (string, bool)

Get returns the value of a key, and if this key is set.

func (*MultiTag) GetMany

func (x *MultiTag) GetMany(key string) []string

Get returns the values of a key, and if this key is set.

func (*MultiTag) Parse

func (x *MultiTag) Parse() error

Parse scans the struct tag string for all keys and their values.

func (*MultiTag) Set

func (x *MultiTag) Set(key string, value string)

Set changes the value of a key in the cache.

func (*MultiTag) SetMany

func (x *MultiTag) SetMany(key string, value []string)

SetMany stores some values in the cache, for the given key.
