An SSA variable that represents an uncertain implicit update of the value.
This is a Call
that might reach a non-local update of the field or one of
its qualifiers.

Predicates
getPriorDef | Gets the immediately preceding definition. Since this update is uncertain the value from the preceding definition might still be valid. |
Inherited predicates
assignsUnknownValue | Holds if this ssa variable might change the value to something unknown. | from SsaImplicitUpdate |
getAFirstUse | Gets an access of the SSA source variable underlying this SSA variable that can be reached from this SSA variable without passing through any other uses, but potentially through phi nodes and uncertain implicit updates. | from SsaVariable |
getANonLocalUpdate | Gets a reachable | from SsaImplicitUpdate |
getAPhiInputOrPriorDef | Gets an SSA variable whose value can flow to this one in one step. This includes inputs to phi nodes, the prior definition of uncertain updates, and the captured ssa variable for a closure variable. | from SsaVariable |
getAUse | Gets an access of this SSA variable. | from SsaVariable |
getAnUltimateDefinition | Gets a definition that ultimately defines this variable and is not itself a phi node. | from SsaVariable |
getBasicBlock | Gets the | from SsaVariable |
getCfgNode | Gets the | from SsaVariable |
getLocation | Gets the source location for this element. | from SsaVariable |
getSourceVariable | Gets the SSA source variable underlying this SSA variable. | from SsaVariable |
isLiveAtEndOfBlock | Holds if this SSA variable is live at the end of | from SsaVariable |
toString | Gets a textual representation of this SSA variable. | from SsaImplicitUpdate |
