Predicates

dominates	Whether this basic block dominates the other
getASuccessor	Gets a successor to this basic block
getASuccessor	Gets an immediate successor of this basic block of a given type, if any.
getImmediateDominator	Gets the basic block that immediately dominates this basic block, if any.
getLocation	Gets the location of this basic block.
inDominanceFrontier	Holds if `df` is in the dominance frontier of this basic block. That is, this basic block dominates a predecessor of `df`, but does not dominate `df` itself. I.e., it is equivaluent to: `this.dominates(df.getAPredecessor()) and not this.strictlyDominates(df)`
length	Gets the length of this basic block.
postDominates	Unsupported. Do not use.
strictlyDominates	Whether this basic block strictly dominates the other
strictlyPostDominates	Unsupported. Do not use.

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
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
firstNode	Gets the first node in this basic block	from BasicBlock
getAFalseSuccessor	Gets a false successor to this basic block	from BasicBlock
getAPredecessor	Gets a predecessor 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
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
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
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
