getABasicBlockSuccessor	Gets an immediate successor of basic block `bb`, if any.
getBlockId1	Gets an ideally unique integer for `bb`. If it is undesirable to make this unique, then `getBlock2` must provide a tiebreaker, such that the pair `(getBlockId1(bb),getBlockId2(bb))` becomes unique.
getExprType	Gets the type of an expression.
getSsaType	Gets the type of an SSA variable.

SsaExplicitUpdate	An SSA variable representing the value of an explicit update of the source variable.
SsaPhiNode	A phi node in the SSA form. A phi node is a kind of node in the SSA form that represents a merge point where multiple control flow paths converge and the value of a variable needs to be selected according to which control flow path was taken. For example, in the following Ruby code: `rb if b x = 0 else x = 1 end puts x` A phi node for `x` is inserted just before the call `puts x`, since the value of `x` may come from either `x = 0` or `x = 1`.
SsaVariable	A static single-assignment (SSA) variable.

BasicBlock	A basic block, that is, a maximal straight-line sequence of control flow nodes without branches or joins.
ConditionalExpr	A conditional expression of the form `a ? b : c`, where `a` is the condition, `b` is the expression that is evaluated if the condition evaluates to `true`, and `c` is the expression that is evaluated if the condition evaluates to `false`.
ConstantIntegerExpr	An expression that always has the same integer value.
Expr	A common super-class that represents all kinds of expressions.
RelationalExpr	A comparison expression.
Type	A common abstraction for all Java types, including primitive, class, interface and array types.
additionalValueFlowStep	Holds if `e1 + delta` equals `e2`.
conversionCannotOverflow	Holds if a cast from `fromtyp` to `totyp` can be ignored for the purpose of range analysis.
