Detailed Description
Types used by chert backend and the Btree manager.
Definition in file chert_types.h.
Macro Definition Documentation
◆ CHERT_DEFAULT_BLOCK_SIZE
| #define CHERT_DEFAULT_BLOCK_SIZE 8192 |
The default block size to use in a B-tree table.
If this is changed, be sure to update the API documentation correspondingly.
Definition at line 57 of file chert_types.h.
◆ CHERT_MAX_DOCID
| #define CHERT_MAX_DOCID Xapian::docid(0xffffffff) |
The largest docid value supported by chert.
Definition at line 60 of file chert_types.h.
Typedef Documentation
◆ chert_blocksize_t
| typedef unsigned int chert_blocksize_t |
Definition at line 28 of file chert_types.h.
◆ chert_doclen_t
| typedef unsigned int chert_doclen_t |
An integer type for storing the length of a document - ie, the sum of the wdfs of the terms in the document.
Definition at line 51 of file chert_types.h.
◆ chert_revision_number_t
| typedef unsigned int chert_revision_number_t |
A type used to store a revision number for a table.
A table's revision number increases monotonically, incrementing by one each time a modification is applied to the table.
FIXME: ensure that this is of a suitable minimum size - 32 bits is satisfactory in most cases, but in extreme cases could cause the revision number to roll over after a few years. It would be better to use 64 bits (and / or to ensure that rolling over causes no problem).
Definition at line 40 of file chert_types.h.
◆ chert_tablesize_t
| typedef unsigned long long chert_tablesize_t |
A type used to store the number of entries in a table.
Again, this must be of suitable minimum size.
