CodeQL library for C#

codeql/csharp-all 6.0.2 (changelog, source)

Class Ssa::PhiNode

DEPRECATED: Use SsaPhiDefinition instead.

An SSA phi node, that is, a pseudo definition for a variable at a point in the flow graph where otherwise two or more definitions for the variable would be visible.

Predicates

getAnInput	Gets an input of this phi node. Example:
hasInputFromBlock	Holds if `inp` is an input to this phi node along the edge originating in `bb`.

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	DEPRECATED: Use `ssaGetAFirstUse` instead.	from Definition
getAFirstReadAtNode	DEPRECATED: Use `ssaGetAFirstUse` instead.	from Definition
getARead	Gets a read of the source variable underlying this SSA definition that can be reached from this SSA definition without passing through any other SSA definitions. Example:	from Definition
getAReadAtNode	DEPRECATED: Use `getARead()` instead.	from Definition
getAnUltimateDefinition	Gets a definition that ultimately defines this SSA definition and is not itself a phi node. Example:	from Definition
getBasicBlock	Gets the basic block to which this SSA definition belongs.	from Definition
getControlFlowNode	Gets the control flow node of this SSA definition.	from Definition
getElement	Gets the syntax element associated with this SSA definition, if any. This is either an expression, for example `x = 0`, a parameter, or a callable. Phi nodes have no associated syntax element.	from Definition
getEnclosingCallable	DEPRECATED: Use `getSourceVariable().getEnclosingCallable()` instead.	from Definition
getLocation	Gets the location of this SSA definition.	from Definition
getSourceVariable	Gets the source variable underlying this SSA definition.	from Definition
isLiveAtEndOfBlock	Holds if this SSA definition is live at the end of basic block `bb`. That is, this definition reaches the end of basic block `bb`, at which point it is still live, without crossing another SSA definition of the same source variable.	from Definition
isLiveOutRefParameterDefinition	DEPRECATED.	from Definition
toString	Gets a textual representation of this SSA definition.	from PhiNode
