Methods

fetch

fetch(key, opts?): Promise<undefined | MediaBlob>
Parameters
- key: string | MediaBlob
- opts: BlobStoreFetchOptions = {}
Returns Promise<undefined | MediaBlob>
Inherited from BlobStore.fetch
- Defined in libs/langchain-google-common/src/experimental/utils/media_core.ts:409

hasValidPath

hasValidPath(path, _opts?): Promise<boolean>
Is the path supported by this BlobStore?

Although this is async, this is expected to be a relatively fast operation (ie - you shouldn't make network calls).
Parameters
- path: string
  The path to check
- Optional_opts: BlobStoreStoreOptions
Returns Promise<boolean>
If the path is supported
Overrides BlobStore.hasValidPath

mdelete

mdelete(_keys): Promise<void>
Abstract method to delete multiple keys.
Parameters

- A Promise that resolves when the operation is complete.
Overrides BlobStore.mdelete
- Defined in libs/langchain-google-common/src/experimental/utils/media_core.ts:580

mget

mget(keys): Promise<(undefined | MediaBlob)[]>
Abstract method to get multiple values for a set of keys.
Parameters
- keys: string[]
  An array of keys.
Returns Promise<(undefined | MediaBlob)[]>
- A Promise that resolves with array of values or undefined if key not found.
Overrides BlobStore.mget
- Defined in libs/langchain-google-common/src/experimental/utils/media_core.ts:575

mset

mset(_keyValuePairs): Promise<void>
Abstract method to set a value for multiple keys.
Parameters
- _keyValuePairs: [string, MediaBlob][]
Returns Promise<void>
- A Promise that resolves when the operation is complete.
Overrides BlobStore.mset
- Defined in libs/langchain-google-common/src/experimental/utils/media_core.ts:584

store

store(blob, opts?): Promise<undefined | MediaBlob>
Parameters
- blob: MediaBlob
- opts: BlobStoreStoreOptions = {}
Returns Promise<undefined | MediaBlob>
Inherited from BlobStore.store
- Defined in libs/langchain-google-common/src/experimental/utils/media_core.ts:372

yieldKeys

yieldKeys(_prefix): AsyncGenerator<string, any, unknown>
Abstract method to yield keys optionally based on a prefix.
Parameters
- _prefix: undefined | string
Returns AsyncGenerator<string, any, unknown>
- An asynchronous generator that yields keys on iteration.
