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.

• Readonlyincludes: (a: string, b: string) => boolean

  Reports whether the first expression selects every key the second one selects.

• Readonlyintersects: (a: string, b: string) => boolean

  Reports whether two key expressions share at least one key, the relation Zenoh routes by.

• ReadonlyisCanon: (key: string) => boolean

  Reports whether a key expression is already in its canonical form, the only form a Zenoh session accepts.

• ReadonlyisValid: (key: string) => boolean

  Reports whether a key expression is well formed.

• Readonlyjoin: (prefix: string, suffix: string) => string | null

  Joins two key expressions with a / and canonizes the result, or returns null if either side is empty or the joined expression is malformed.

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

  Reports whether a pattern selects a concrete key.
