Inherited fields

instr		from InstructionDirectParameterNode
node		from InstructionNode

Predicates

isParameterOf	Holds if this node is the parameter of `f` at the specified position. The implicit `this` parameter is considered to have position `-1`, and pointer-indirection parameters are at further negative positions.
toStringImpl	INTERNAL: Do not use.

Inherited predicates

asConvertedExpr	Gets the expression corresponding to this node, if any. The returned expression may be a `Conversion`.	from Node
asConvertedExpr	Gets the expression corresponding to this node, if any. The returned expression may be a `Conversion`.	from Node
asDefiningArgument	Gets the argument that defines this `DefinitionByReferenceNode`, if any. This predicate should be used instead of `asExpr` when referring to the value of a reference argument after the call has returned. For example, in `f(&x)`, this predicate will have `&x` as its result for the `Node` that represents the new value of `x`.	from Node
asDefiningArgument	Gets the argument that defines this `DefinitionByReferenceNode`, if any.	from Node
asDefinition	Gets the definition associated with this node, if any.	from Node
asExpr	Gets the non-conversion expression corresponding to this node, if any. This predicate only has a result on nodes that represent the value of evaluating the expression. For data flowing out of an expression, like when an argument is passed by reference, use `asDefiningArgument` instead of `asExpr`.	from Node
asExpr	INTERNAL: Do not use.	from Node
asIndirectArgument	Gets the the argument going into a function for a node that represents the indirect value of the argument after any non-zero number of loads.	from Node
asIndirectArgument	Gets the the argument going into a function for a node that represents the indirect value of the argument after `index` loads. For example, in: `cpp void f(int); ... int x = ...; f(x);` The node `n` such that `n.asIndirectArgument(1)` represents the value of `x` going into `f`, and the node `n` such that `n.asIndirectArgument(2)` represents the value of `*x` going into `f`.	from Node
asIndirectConvertedExpr	Gets the expression that’s indirectly tracked by this node behind a number of indirections.	from Node
asIndirectConvertedExpr	Gets the expression that’s indirectly tracked by this node behind `index` number of indirections.	from Node
asIndirectConvertedExpr	INTERNAL: Do not use.	from Node
asIndirectDefinition	Gets the indirect definition at some indirection corresponding to this node, if any.	from Node
asIndirectDefinition	Gets the indirect definition at a given indirection corresponding to this node, if any.	from Node
asIndirectExpr	Gets the non-conversion expression that’s indirectly tracked by this node behind a number of indirections.	from Node
asIndirectExpr	Gets the non-conversion expression that’s indirectly tracked by this node under `index` number of indirections.	from Node
asIndirectExpr	INTERNAL: Do not use.	from Node
asIndirectOperand	Gets the operand that is indirectly tracked by this node behind `index` number of indirections.	from Node
asIndirectVariable	Gets an indirection of this node’s underlying variable, if any.	from Node
asIndirectVariable	Gets the `indirectionIndex`’th indirection of this node’s underlying variable, if any.	from Node
asInstruction	Gets the instruction corresponding to this node, if any.	from Node
asOperand	Gets the operands corresponding to this node, if any.	from Node
asParameter	Gets the positional parameter corresponding to this node, if any.	from Node
asParameter	Gets the positional parameter corresponding to the node that represents the value of the parameter after `index` number of loads, if any. For example, in: `cpp void f(int** x) { ... }` - The node `n` such that `n.asParameter(0)` is the parameter `x` represents the value of `x`. - The node `n` such that `n.asParameter(1)` is the parameter `x` represents the value of `x`. - The node `n` such that `n.asParameter(2)` is the parameter `x` represents the value of `*x`.	from Node
asPartialDefinition	Gets the expression that is partially defined by this node, if any.	from Node
asUninitialized	Gets the uninitialized local variable corresponding to this node, if any.	from Node
asVariable	Gets the variable corresponding to this node, if any. This can be used for modeling flow in and out of global variables.	from Node
getBasicBlock	Gets the basic block of this node, if any.	from Node
getEnclosingCallable	INTERNAL: Do not use.	from Node0
getFunction	Gets the function to which this node belongs, if any.	from Node0
getIRVariable	INTERNAL: Do not use.	from InstructionDirectParameterNode
getInstruction	Gets the instruction corresponding to this node.	from InstructionNode
getLocation	Gets the location of this element.	from Node
getLocationImpl	INTERNAL: Do not use.	from Node0
getParameter	Gets the `Parameter` associated with this node, if it exists.	from AbstractParameterNode
getType	Gets the type of this node.	from Node0
getTypeBound	Gets an upper bound on the type of this node.	from Node
hasIndexInBlock	Holds if this node is at index `i` in basic block `block`.	from Node
hasLocationInfo	Holds if this element is at the specified location. The location spans column `startcolumn` of line `startline` to column `endcolumn` of line `endline` in file `filepath`. For more information, see Locations.	from Node
isGLValue	Holds if this node represents a glvalue.	from Node0
toString	Gets a textual representation of this element.	from Node
