| Interface | Description |
|---|---|
| ExpressionVisitor |
An interface for using the Visitor pattern for traversing expressions.
|
| Class | Description |
|---|---|
| AbstractExpressionVisitor |
A default implementation of an expression visitor, that simply visits all
the nodes in the tree.
|
| CircularReferenceFinder |
An expression visitor that looks for circular references in a formula, i.e.
|
| ExpressionBuilder |
A base-class for classes that rebuild expressions.
|
| ExpressionTreePrinter |
A class for printing expressions on multiple lines with indentation.
|
| Interpreter |
A base-class for customized formula interpreters.
|
| ReferenceFetcher |
An expression visitor that collects the references from an expression.
|
| ReferenceTransposer |
An expression visitor that transposes the references in an expression.
|
| Exception | Description |
|---|---|
| CircularReferenceException |
An exception that is thrown if a formula contains a reference (directly or
indirectly) to the cell in which it is contained.
|
| ExpressionVisitorException |
A base-class for exceptions thrown when traversing an expression tree.
|
Provides utilities for performing operations on formulas. Classes that perform
operations on expression trees must implement the ExpressionVisitor
interfacce, either directly or by extending one of the base-classes:
AbstractExpressionVisitor - that simply visits all nodes in the tree
ExpressionBuilder - that copies a given expression
ExpressionVisitors may throw ExpressionVisitorException
s, or sub-classes thereof.
