Class BearerAbstract

constructor

• new Bearer(): Bearer

  Describes a credential source and creates receivers for it.

  Use a concrete bearer such as StaticBearer, FileBearer, or ServiceAccountBearer. Pass that bearer as SDKOptions.credentials. A bearer can own timers or other resources, so close the SDK when the application shuts down.

  Returns Bearer

acquisitionBudgetMs

• get acquisitionBudgetMs(): number | undefined

  Returns the budget for one token acquisition, in milliseconds.

  Returns string

name

• get name(): string | undefined

wrapped

• get wrapped(): Bearer | undefined

  Returns the next bearer in a wrapper chain, when this bearer wraps another source.
