Detailed Description

Common ancestor of SQL statements that deal with directory entries.

Member Function Documentation

unsigned catalog::SqlDirent::CreateDatabaseFlags ( const DirectoryEntry & entry ) const

protected

Take the meta data from the DirectoryEntry and transform it into a valid flags field ready to be saved in the database.

Parameters

entry the DirectoryEntry to encode

Returns: an integer containing the bitmap of the flags field

Definition at line 437 of file catalog_sql.cc.

Here is the call graph for this function:

void catalog::SqlDirent::ExpandSymlink ( LinkString * raw_symlink ) const

protected

Replaces place holder variables in a symbolic link by actual path elements.

Parameters

raw_symlink the raw symlink path (may) containing place holders

Returns: the expanded symlink

Expands variant symlinks containing string. Uses the environment variables of the current process (cvmfs2)

Definition at line 524 of file catalog_sql.cc.

Here is the call graph for this function:

uint32_t catalog::SqlDirent::Hardlinks2HardlinkGroup ( const uint64_t hardlinks ) const

protected

Definition at line 507 of file catalog_sql.cc.

uint32_t catalog::SqlDirent::Hardlinks2Linkcount ( const uint64_t hardlinks ) const

protected

The hardlink information (hardlink group ID and linkcount) is saved in one uint_64t field in the CVMFS Catalogs. Therefore we need to do bitshifting in these helper methods.
