Form a denotation by conjoining with denotation that.
Form a denotation by conjoining with denotation that.
NoDenotations are dropped. MultiDenotations are handled by merging parts with same signatures. SingleDenotations with equal signatures are joined as follows:
In a first step, consider only those denotations which have symbols
that are accessible from prefix pre.
If there are several such denotations, try to pick one by applying the following three precedence rules in decreasing order of priority:
If there is exactly one (preferred) accessible denotation, return it.
If there is no preferred accessible denotation, return a JointRefDenotation
with one of the operand symbols (unspecified which one), and an info which
is the intersection (using & or safe_& if safeIntersection is true)
of the infos of the operand denotations.
If SingleDenotations with different signatures are joined, return NoDenotation.
The denotation made up from the alternatives of this denotation that
are accessible from prefix pre, or NoDenotation if no accessible alternative exists.

Resolve overloaded denotation to pick the ones with the given signature

When true, consider only parameter signatures for a match.

Produce a denotation that is valid for the given context.
Produce a denotation that is valid for the given context. Usually called when !(validFor contains ctx.period) (even though this is not a precondition). If the runId of the context is the same as runId of this denotation, the right flock member is located, or, if it does not exist yet, created by invoking a transformer (@See Transformers). If the runId's differ, but this denotation is a SymDenotation and its toplevel owner class or module is still a member of its enclosing package, then the whole flock is brought forward to be valid in the new runId. Otherwise the symbol is stale, which constitutes an internal error.
If this denotation is overloaded, filter with given predicate.
If this denotation is overloaded, filter with given predicate. If result is still overloaded throw a TypeError. Note: disambiguate is slightly different from suchThat in that single-denotations that do not satisfy the predicate are left alone (whereas suchThat would map them to NoDenotation).

Install this denotation to be the result of the given denotation transformer.
Install this denotation to be the result of the given denotation transformer. This is the implementation of the same-named method in SymDenotations. It's placed here because it needs access to private fields of SingleDenotation.

prevDenots.pre does not appear in ownDenots
Return the denotation as seen from pre.
Called from SymDenotations.computeMember. There, ownDenots are the denotations found in
the base class, which shadow any inherited denotations with the same signature.
prevDenots are the denotations that are defined in the class or inherited from
a base type which comes earlier in the linearization.
