Member Function Documentation
◆ at_end()
|
inlinevirtual |
Return true if the current position is past the last term in this list.
Implements Xapian::TermIterator::Internal.
Definition at line 232 of file matchspy.cc.
References Assert.
◆ get_approx_size()
|
inlinevirtual |
Return approximate size of this termlist.
Implements Xapian::TermIterator::Internal.
Definition at line 237 of file matchspy.cc.
References unsupported_method().
◆ get_termfreq()
|
inlinevirtual |
Return the term frequency for the term at the current position.
Implements Xapian::TermIterator::Internal.
Definition at line 208 of file matchspy.cc.
References Assert.
◆ get_termname()
|
inlinevirtual |
Return the termname at the current position.
Implements Xapian::TermIterator::Internal.
Definition at line 202 of file matchspy.cc.
References Assert.
◆ get_wdf()
|
inlinevirtual |
Return the wdf for the term at the current position.
Implements Xapian::TermIterator::Internal.
Definition at line 238 of file matchspy.cc.
References unsupported_method().
◆ init()
|
inline |
init should be called after the values have been set, but before iteration begins.
Definition at line 197 of file matchspy.cc.
◆ next()
|
inlinevirtual |
Advance the current position to the next term in the termlist.
The list starts before the first term in the list, so next(), skip_to() or check() must be called before any methods which need the context of the current position.
- Returns
- If a non-NULL pointer is returned, then the caller should substitute the returned pointer for its pointer to us, and then delete us. This "pruning" can only happen for a non-leaf subclass of this class.
Implements Xapian::TermIterator::Internal.
Definition at line 214 of file matchspy.cc.
References Assert.
◆ positionlist_begin()
|
inlinevirtual |
Return a PositionIterator for the current position.
Implements Xapian::TermIterator::Internal.
Definition at line 239 of file matchspy.cc.
References unsupported_method().
◆ positionlist_count()
|
inlinevirtual |
Return the length of the position list for the current position.
Implements Xapian::TermIterator::Internal.
Definition at line 243 of file matchspy.cc.
References unsupported_method().
◆ skip_to()
|
inlinevirtual |
Skip forward to the specified term.
If the specified term isn't in the list, position ourselves on the first term after tname (or at_end() if no terms after tname exist).
Implements Xapian::TermIterator::Internal.
