An SSA phi node.

Import path

import semmle.code.java.dataflow.SSA

Direct supertypes

Indirect supertypes

Predicates

getAPhiInput

Gets an input to the phi node defining the SSA variable.

hasInputFromBlock

Holds if inp is an input to the phi node along the edge originating in bb.

toString

Gets a textual representation of this SSA variable.

Inherited predicates

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
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 BasicBlock in which this SSA variable is defined.

from SsaVariable
getCFGNode

DEPRECATED: Alias for getCfgNode

from SsaVariable
getCfgNode

Gets the ControlFlowNode at which this SSA variable is defined.

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 b.
