CombinedBinaryExpression is an implementation of BinaryExpression that
specifically attempts to mitigate the issues raised by expressions which
have a very deep leftmost branch. It does so by maintaining a table of
direct references to its subexpressions, and implementing non-recursive
variants of the most significant recursive algorithms of its ancestors.
The subexpressions table only holds intermediate binary expressions. Its
role is to provide the reversed navigation through the left relationship
of BinaryExpression to Expression. To cope with potentially very deep
left branches, an instance of CombinedBinaryExpression is created once in
a while, using variable thresholds held by
Notes:
arityMax
.
As a specific case, the topmost node of all binary expressions that are
deeper than one is a CombinedBinaryExpression, but it has no references
table.Notes:
- CombinedBinaryExpression is not meant to behave in other ways than BinaryExpression in any observable respect;
- visitors that implement their own traversal upon binary expressions should consider taking advantage of combined binary expressions, or else face a risk of StackOverflowError upon deep instances;
- callers that need to change the operator should rebuild the expression from scratch, or else amend the references table as needed to cope with the resulting, separated expressions.

Field Details

arity
public int arityThe number of consecutive binary expressions of this' left branch that bear the same operator as this.
Notes:- the presence of a CombinedBinaryExpression instance resets arity, even when its operator is compatible;
- this property is maintained by the parser.
-
arityMax
public int arityMaxThe threshold that will trigger the creation of the next full-fledged CombinedBinaryExpression. This field is only maintained for the topmost binary expression (it is 0 otherwise). It enables a variable policy, which scales better with very large expressions. -
ARITY_MAX_MAX
public static final int ARITY_MAX_MAXUpper limit forarityMax
.- See Also:
- Constant Field Values
-
ARITY_MAX_MIN
public static final int ARITY_MAX_MINDefault lower limit forarityMax
.- See Also:
- Constant Field Values
-
defaultArityMaxStartingValue
public static int defaultArityMaxStartingValueDefault value for the first term of the series ofarityMax
values. Changing this allows for experimentation. Not meant to be changed during a parse operation. -
referencesTable
A table of references to the binary expressions of this' left branch. Instances of CombinedBinaryExpression are not repeated here. Instead, the left subexpression of referencesTable[0] may be a combined binary expression, if appropriate. Null when this only cares about tracking the expression's arity.

CombinedBinaryExpression
Make a new CombinedBinaryExpression. If arity is strictly greater than one, a references table is built and initialized with the reverse relationship of the one defined byBinaryExpression.left
. arity and left must be compatible with each other (that is, there must be at least arity - 1 consecutive compatible binary expressions into the leftmost branch of left, the topmost of which being left's immediate left expression).- Parameters:
left
- the left branch expressionright
- the right branch expressionoperator
- the operator for this binary expression - only PLUS for nowarity
- the number of binary expressions of a compatible operator that already exist into the leftmost branch of left (including left); must be strictly greater than 0
