Macro Definition Documentation

◆ GLASS_DEFAULT_BLOCKSIZE

#define GLASS_DEFAULT_BLOCKSIZE   8192

Default B-tree block size.

Definition at line 30 of file glass_defs.h.

Referenced by GlassDatabase::compact(), and GlassDatabase::GlassDatabase().

◆ GLASS_MAX_BLOCKSIZE

#define GLASS_MAX_BLOCKSIZE   65536

Maximum B-tree block size.

Definition at line 36 of file glass_defs.h.

◆ GLASS_MAX_DOCID

#define GLASS_MAX_DOCID   Xapian::docid(0xffffffffffffffff)

The largest docid value supported by glass.

The disk format supports 64-bit docids, but if Xapian::docid is narrower then it's the largest value supported by the type that matters here.

Definition at line 43 of file glass_defs.h.

Referenced by GlassWritableDatabase::add_document(), GlassPostListTable::get_used_docid_range(), and Glass::ValueUpdater::update().

◆ GLASS_MIN_BLOCKSIZE

#define GLASS_MIN_BLOCKSIZE   2048

Minimum B-tree block size.

Definition at line 33 of file glass_defs.h.

Referenced by test_if_single_file_db().

◆ GLASS_TABLE_EXTENSION

#define GLASS_TABLE_EXTENSION   "glass"

Typedef Documentation

◆ glass_block_t

A block number in a glass Btree file.

Definition at line 58 of file glass_defs.h.

◆ glass_revision_number_t

The revision number of a glass database.

Definition at line 61 of file glass_defs.h.

◆ glass_tablesize_t

typedef unsigned long long glass_tablesize_t

How many entries there are in a table.

Definition at line 64 of file glass_defs.h.
