Class Ssa :: Definition

A static single assignment (SSA) definition. Either an explicit variable definition (ExplicitDefinition), an implicit variable definition (ImplicitDefinition), or a phi node (PhiNode).

Predicates

getAFirstRead	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 definition or read. Example:
getAFirstReadAtNode	Gets a read of the source variable underlying this SSA definition at control flow node `cfn` that can be reached from this SSA definition without passing through any other SSA definition or read. Example:
getALastRead	Gets a last read of the source variable underlying this SSA definition. That is, a read that can reach the end of the enclosing callable, or another SSA definition for the source variable, without passing through any other read. Example:
getALastReadAtNode	Gets a last read of the source variable underlying this SSA definition at control flow node `cfn`. That is, a read that can reach the end of the enclosing callable, or another SSA definition for the source variable, without passing through any other read. Example:
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:
getAReadAtNode	Gets a read of the source variable underlying this SSA definition at control flow node `cfn` that can be reached from this SSA definition without passing through any other SSA definitions. Example:
getAnUltimateDefinition	Gets a definition that ultimately defines this SSA definition and is not itself a phi node. Example:
getControlFlowNode	Gets the control flow node of this SSA definition, if any. Phi nodes are examples of SSA definitions without a control flow node, as they are modeled at index `-1` in the relevant basic block.
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.
getEnclosingCallable	Gets the callable to which this SSA definition belongs.
getLocation	Gets the location of this SSA 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.
isLiveOutRefParameterDefinition	Holds if this SSA definition assigns to `out`/`ref` parameter `p`, and the parameter may remain unchanged throughout the rest of the enclosing callable.

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
getBasicBlock	Gets the basic block to which this SSA definition belongs.	from Definition
getSourceVariable	Gets the source variable underlying this SSA definition.	from Definition
toString	Gets a textual representation of this SSA definition.	from Definition
