Predicates

isLt	Holds if this `SsaDefinition` is guarded such that `this(var) < gt + k` is `testIsTrue` in `block`.

Inherited predicates

definedByParameter	Holds if the SSA variable `(this, p)` is defined by parameter `p`.	from SsaDefinition
getAPhiInput	Holds if the SSA variable `(result, v)` is an input to the phi definition `(this, v)`.	from SsaDefinition
getAPrimaryQlClass	Gets the name of a primary CodeQL class to which this element belongs.	from ElementBase
getAUse	Gets a use of the SSA variable represented by the pair `(this, v)`.	from SsaDefinition
getAVariable	Gets a variable corresponding to an SSA StackVariable defined by this definition.	from SsaDefinition
getAnUltimateDefiningValue	Gets a possible defining expression for `v` at this SSA definition, recursing backwards through phi definitions. Not all definitions have a defining expression—see the documentation for `getDefiningValue`.	from SsaDefinition
getAnUltimateSsaDefinition	Gets a definition that ultimately defines this variable and is not itself a phi node.	from SsaDefinition
getBasicBlock	Gets the `BasicBlock` containing this definition.	from SsaDefinition
getDefiningValue	Gets the expression assigned to the SSA variable `(this, v)`, if any, when it is not a phi definition. The following is an exhaustive list of expressions that may be the result of this predicate.	from SsaDefinition
getDefinition	Gets the control-flow node for this definition. This will usually be the control-flow node that assigns to this variable as a side effect, but there are some exceptions. If `this` is defined by initialization, the result is the value of `Initializer.getExpr()` for that initialization. If `this` is a function parameter (see `definedByParameter`), the result will be the function entry point. If `this` variable is defined by being passed as a reference in a function call, including overloaded operators, the result will be the `VariableAccess` expression for this parameter. If `this` is a phi node (see `isPhiNode`), the result will be the node where control flow is joined from multiple paths.	from SsaDefinition
getLocation	Gets the location of this definition.	from SsaDefinition
getPrimaryQlClasses	Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs.	from ElementBase
isPhiNode	Holds if this definition is a phi node for variable `v`.	from SsaDefinition
reachesEndOfBB	Holds if `(this, v)` reaches the end of basic block `b`.	from SsaDefinition
toString	Gets a textual representation of this element.	from ElementBase
toString	Gets a string representation of the SSA variable represented by the pair `(this, v)`.	from SsaDefinition
