Class VariableNode
A Node
corresponding to a global (or static
local) variable in the
program, as opposed to the value of that variable at some particular point.
This is used to model flow through global variables (and static
local
variables).
There is no VariableNode
for non-static
local variables.

getFunction | Gets the function to which this node belongs, if any. |
getIndirectionIndex | Gets the indirection index of this node. |

Inherited predicates
asConvertedExpr | Gets the expression corresponding to this node, if any. The returned expression may be a | from Node |
asConvertedExpr | Gets the expression corresponding to this node, if any. The returned expression may be a | from Node |
asDefiningArgument | Gets the argument that defines this | from Node |
asDefiningArgument | Gets the argument that defines this | from Node |
asDefinition | Gets the definition associated with this node, if any. | from Node |
asExpr | Gets the non-conversion expression corresponding to this node, if any. This predicate only has a result on nodes that represent the value of evaluating the expression. For data flowing out of an expression, like when an argument is passed by reference, use | from Node |
