Types

type Kind

type Kind = reflect.Kind

type Pattern

type Pattern string

Pattern is a resource pattern that may contain wildcards and tags.

Pattern("example.resource.>") // Full wild card (>) matches anything that follows
Pattern("example.item.*")     // Wild card (*) matches a single part
Pattern("example.model.$id")  // Tag (starting with $) matches a single part

func (Pattern) IndexWildcard

func (p Pattern) IndexWildcard() int

IndexWildcard returns the index of the first instance of a wild card (*, >, or $tag) in pattern, or -1 if no wildcard is present.

Behavior is undefined for an invalid pattern.

func (Pattern) IsValid

func (p Pattern) IsValid() bool

IsValid returns true if the pattern is valid, otherwise false.

func (Pattern) Matches

func (p Pattern) Matches(s string) bool

Matches tests if the resource name, s, matches the pattern.

The resource name might in itself contain wild cards and tags.

Behavior is undefined for an invalid pattern or an invalid resource name.

func (Pattern) ReplaceTag

func (p Pattern) ReplaceTag(tag string, value string) Pattern

ReplaceTag searches for a given tag (without $) and replaces it with the value.

Behavior is undefined for an invalid pattern.

func (Pattern) ReplaceTags

func (p Pattern) ReplaceTags(m map[string]string) Pattern

ReplaceTags searches for tags and replaces them with the map value for the key matching the tag (without $).

Behavior is undefined for an invalid pattern.

func (Pattern) Values

func (p Pattern) Values(s string) (map[string]string, bool)

Values extracts the tag values from a resource name, s, matching the pattern.

The returned bool flag is true if s matched the pattern, otherwise false with a nil map.

Behavior is undefined for an invalid pattern or an invalid resource name.

type Tokenize

type Tokenize string

Tokenize is a resource Tokenize that may contain wildcards and tags.

Tokenize("example.resource.>") // Full wild card (>) matches anything that follows
Tokenize("example.item.*")     // Wild card (*) matches a single part
Tokenize("example.model.$id")  // Tag (starting with $) matches a single part

func (Tokenize) IndexWildcard

func (p Tokenize) IndexWildcard() int

IndexWildcard returns the index of the first instance of a wild card (*, >, or $tag) in Tokenize, or -1 if no wildcard is present.

Behavior is undefined for an invalid Tokenize.

func (Tokenize) IsValid

func (p Tokenize) IsValid() bool

IsValid returns true if the Tokenize is valid, otherwise false.

func (Tokenize) Matches

func (p Tokenize) Matches(s string) bool

Matches tests if the resource name, s, matches the Tokenize.

The resource name might in itself contain wild cards and tags.

Behavior is undefined for an invalid Tokenize or an invalid resource name.

func (Tokenize) ReplaceTag

func (p Tokenize) ReplaceTag(tag string, value string) Tokenize

ReplaceTag searches for a given tag (without $) and replaces it with the value.

Behavior is undefined for an invalid Tokenize.

func (Tokenize) ReplaceTags

func (p Tokenize) ReplaceTags(m map[string]string) Tokenize

ReplaceTags searches for tags and replaces them with the map value for the key matching the tag (without $).

Behavior is undefined for an invalid Tokenize.

func (Tokenize) Trim

func (p Tokenize) Trim(s string) Tokenize

func (Tokenize) Values

func (p Tokenize) Values(s string) (map[string]string, bool)

Values extracts the tag values from a resource name, s, matching the Tokenize.

The returned bool flag is true if s matched the Tokenize, otherwise false with a nil map.

Behavior is undefined for an invalid Tokenize or an invalid resource name.
