Predicates

getResultType	Gets the type of the result of this instruction, if any.
getResultVariable	Gets the result variable being assigned.
getRhs	Gets the instruction computing the value this instruction writes.
getRoot	Gets the innermost function or file to which this node belongs.
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.
toString	Gets a textual representation of this control flow node.

isJoin	Holds if this is a node with more than one predecessor.	from Node
isPlatformIndependentConstant	Holds if the result of this instruction is known at compile time, and is guaranteed not to depend on the platform where it is evaluated.	from Instruction
reads	Holds if this instruction reads the value of variable or constant `v`.	from Instruction
readsElement	Holds if this instruction reads the value of element `index` on the value of `base`.	from Instruction
readsField	Holds if this instruction reads the value of field `f` on the value of `base`.	from Instruction
readsMethod	Holds if this instruction looks up method `m` on the value of `receiver`.	from Instruction
writes	Holds if this instruction updates variable or constant `v` to the value of `rhs`.	from WriteInstruction
writesElement	Holds if this instruction updates the value of element `index` on the value of `base`.	from Instruction
writesField	Holds if this instruction updates the value of field `f` on the value of `base`.	from Instruction
