Variable keyexprConst

Type Declaration

• Readonlycanonize: (key: string) => string | null

  Rewrites a key expression into its canonical form, or null if it is malformed.

  Two expressions that select the same data have one canonical form, so canonizing before comparing or routing avoids treating a/**/**/b and a/**/b as different.

• ReadonlyisCanon: (key: string) => boolean

  Reports whether a key expression is already in its canonical form.

• ReadonlyisValid: (key: string) => boolean

  Reports whether a key expression is well formed.

• Readonlymatches: (pattern: string, key: string) => boolean

  Reports whether a pattern selects a key.
