Predicates

getAnInput	Gets an input of this pseudo-definition.
getKind	INTERNAL: Do not use.

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
getAFirstUse	Gets the first instruction that the value of this `SsaDefinition` can reach without passing through any other instructions, but possibly through phi nodes.	from SsaDefinition
getBasicBlock	Gets the basic block to which this SSA definition belongs.	from Definition
getLocation	Gets the location of this SSA definition.	from Definition
getRoot	Gets the innermost function or file to which this SSA definition belongs.	from SsaDefinition
getSourceVariable	Gets the source variable underlying this SSA definition.	from Definition
getVariable	Gets the SSA variable defined by this definition.	from SsaDefinition
hasLocationInfo	DEPRECATED: Use `getLocation()` instead.	from SsaDefinition
toString	Gets a textual representation of this SSA definition.	from PhiNode
