Member Function Documentation

◆ credentials()

virtual std::vector< StorageCredential > iceberg::SupportsStorageCredentials::credentials ( ) const

pure virtual

Return the storage credentials this FileIO holds.

By value because a concurrent install may replace them. An implementation that delegates may report what was installed on it.

Implemented in iceberg::ResolvingFileIO.

◆ InitializeStorageCredentials()

virtual Status iceberg::SupportsStorageCredentials::InitializeStorageCredentials	(	const std::vector< StorageCredential > &	storage_credentials,
		std::shared_ptr< StorageCredentialProvider >	provider
	)

inlinevirtual

Install initial credentials and their refresh source before first use.

The default implementation supports static credentials only.

Reimplemented in iceberg::ResolvingFileIO.

◆ SetStorageCredentials()

virtual Status iceberg::SupportsStorageCredentials::SetStorageCredentials ( const std::vector< StorageCredential > & storage_credentials )
