Member Function Documentation
◆ get_approx_size()
|
virtual |
Return approximate size of this termlist.
Implements AllTermsList.
Definition at line 56 of file glass_alltermslist.cc.
◆ get_termfreq()
|
virtual |
Returns the term frequency of the current term.
Either next() or skip_to() must have been called before this method can be called.
Implements AllTermsList.
Definition at line 65 of file glass_alltermslist.cc.
◆ next()
|
virtual |
Advance to the next term in the list.
Implements AllTermsList.

◆ read_termfreq()
|
private |
Read and cache the term frequency.
Definition at line 35 of file glass_alltermslist.cc.
References Assert, LOGCALL_VOID, p, and GlassPostList::read_freqs().
◆ skip_to()
|
virtual |
Advance to the first term which is >= tname.

Member Data Documentation
◆ cursor
|
private |
A cursor which runs through the postlist table reading termnames from the keys.
Definition at line 45 of file glass_alltermslist.h.
◆ database
|
private |
Keep a reference to our database to stop it being deleted.
Definition at line 40 of file glass_alltermslist.h.
◆ prefix
|
private |
The prefix to restrict the terms to.
Definition at line 48 of file glass_alltermslist.h.
◆ termfreq
|
mutableprivate |
The term frequency of the term at the current position.
If this value is zero, then we haven't read the term frequency for the current term yet. We need to call read_termfreq() to read this.
