Direct supertypes

Predicates

getAnInput	Gets an input to this phi node.
getLocation	Gets the location of this SSA definition.
hasLastInputRef	Holds if if `def` is an input to this phi node, and a reference to `def` at index `i` in basic block `bb` can reach this phi node without going through other references.

Inherited predicates

definesAt	Holds if this SSA definition defines `v` at index `i` in basic block `bb`. Phi nodes are considered to be at index `-1`, while normal variable writes are at the index of the control flow node they wrap.	from Definition
getAFirstRead	Gets a first read of this SSA definition.	from Definition
getARead	Gets a read of this SSA definition.	from Definition
getAnUltimateDefinition	Gets a definition that ultimately defines this SSA definition and is not itself a phi node.	from Definition
getBasicBlock	Gets the basic block to which this SSA definition belongs.	from Definition
getSourceVariable	Gets the source variable underlying this SSA definition.	from Definition
getVariableUpdate	Gets the underlying variable update, if any.	from Definition
hasAdjacentReads	Holds if `first` and `second` are adjacent reads of this SSA definition.	from Definition
toString	Gets a textual representation of this SSA definition.	from PhiNode
