Member Function Documentation

u_int64_t zkclient::ZkClientCommon::get_block_group_id ( u_int64_t storage_block_id )

Gets the block group id from the storage block id. i.e. bit 2 ~ bit 48.

Parameters

storage_block_id the given storage block id.

Returns: the block group id.

std::string zkclient::ZkClientCommon::get_block_metadata_path ( u_int64_t block_or_block_group_id )

Given a block or block group id, returns the path to the corresponding metadata. For a non EC block, it is BLOCK_LOCATIONS + ID For an EC block, it is BLOCK_GROUP_LOCATIONS + ID

Parameters

block_or_block_group_id the id of a block or a block group.

Returns: the path to the corresponding metadata.

u_int64_t zkclient::ZkClientCommon::get_index_within_block_group ( u_int64_t storage_block_id )

Gets the index within the block group.

Parameters

storage_block_id the given storage block id.

Returns: the index within the block group.

bool zkclient::ZkClientCommon::is_ec_block ( u_int64_t block_id )

static

true if the highest bit is set to 1. false otherwise.

Parameters

block_id the id of a block (or a block group)

Returns: true or false.
