Predicates

controls	Whether this conditional guard determines that, in block `b`, `l == r + k` if `eq` is true, or `l != r + k` if `eq` is false,
controls	Whether this conditional guard determines that, in block `b`, `l == r + k` if `eq` is true, or `l != r + k` if `eq` is false,
getTest
impliesThat	Whether this conditional guard implies that, in block `b`, the result of `that` is `thatIsTrue`

Inherited predicates

alwaysReaches	Holds if flow from this BasicBlock always reaches `succ`	from BasicBlock
contains	Whether this basic block contains the specified node	from BasicBlock
controls	Basic blocks controlled by this condition, i.e. those BBs for which the condition is testIsTrue	from ConditionBlock
controlsEdge	Holds if this condition controls the edge `pred->succ`, i.e. those edges for which the condition is `testIsTrue`.	from ConditionBlock
dominanceFrontier	Dominance frontier of a node x is the set of all nodes `other` such that `this` dominates a predecessor of `other` but does not strictly dominate `other`	from BasicBlock
dominates	Whether this basic block dominates the other	from BasicBlock
getAFalseSuccessor	Gets a false successor to this basic block	from BasicBlock
getAPredecessor	Gets a predecessor to this basic block	from BasicBlock
getASuccessor	Gets a successor to this basic block	from BasicBlock
getATrueSuccessor	Gets a true successor to this basic block	from BasicBlock
getAnExceptionalSuccessor	Gets an exceptional successor to this basic block	from BasicBlock
getAnUnconditionalSuccessor	Gets an unconditional successor to this basic block	from BasicBlock
getImmediateDominator		from BasicBlock
getImmediatelyControllingBlock	Gets the `ConditionBlock`, if any, that controls this block and does not control any other `ConditionBlock`s that control this block. That is the `ConditionBlock` that is closest dominator.	from BasicBlock
getLastNode	Gets the last node in this basic block	from BasicBlock
getNode	Gets the nth node in this basic block	from BasicBlock
getScope	Gets the scope of this block	from BasicBlock
hasLocationInfo	Holds if this element is at the specified location. The location spans column `startcolumn` of line `startline` to column `endcolumn` of line `endline` in file `filepath`. For more information, see Locations.	from BasicBlock
likelyReachable	Whether (as inferred by type inference) this basic block is likely to be reachable.	from BasicBlock
reaches	Holds if this basic block reaches the other. Is the start of other reachable from the end of this.	from BasicBlock
reachesExit	Whether flow from this basic block reaches a normal exit from its scope	from BasicBlock
strictlyDominates	Whether this basic block strictly dominates the other	from BasicBlock
strictlyReaches	Holds if this basic block strictly reaches the other. Is the start of other reachable from the end of this.	from BasicBlock
toString	Gets a textual representation of this element.	from BasicBlock
unlikelySuccessor	Whether (as inferred by type inference) it is highly unlikely (or impossible) for control to flow from this to succ.	from BasicBlock
