Class Ssa :: ImplicitCallDefinition

An SSA definition representing the potential definition of a variable via a call.

Import path

import csharp

Direct supertypes

Indirect supertypes

Predicates

getAPossibleDefinition

Gets one of the definitions that may contribute to this implicit call definition. That is, a definition that can be reached from the target of this call following zero or more additional calls, and which targets the same assignable as this SSA definition.
getCall

Gets the underlying call.
getLocation

Gets the location of this SSA definition.
toString

Gets a textual representation of this SSA definition.

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

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:

 		from Definition
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:

 		from Definition
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:

 		from Definition
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:

 		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

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:

 		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, 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.

 		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

Gets the callable to which this SSA definition belongs.

 		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

Holds if this SSA definition assigns to out/ref parameter p, and the parameter may remain unchanged throughout the rest of the enclosing callable.
