Class SSA::Ssa::ImplicitDefinition

An SSA definition that does not correspond to an explicit variable definition. Either an implicit initialization of a variable at the beginning of a callable (ImplicitEntryDefinition), an implicit definition via a call (ImplicitCallDefinition), an implicit definition where the qualifier is updated (ImplicitQualifierDefinition), or a definition for a field or property that is not amenable to SSA analysis (ImplicitUntrackedDefinition).

Known direct subtypes

Inherited predicates

definesAt

Holds if this SSA definition is at index i in basic block bb. Phi nodes and entry nodes (captured variables and fields/properties) are considered to be at index -1, while normal variable updates 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 pseudo node. Example:

from Definition
getBasicBlock

Gets the basic block to which this SSA definition belongs.

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. Pseudo nodes have no associated syntax element.

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 is 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.

from Definition
toString

Gets a textual representation of this SSA definition.
