Fields

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.

toString

Gets a textual representation of this element.

Inherited predicates

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
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
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
asPartialDefinition

Gets the expression that is partially defined by this node, if any.

from Node
asUninitialized

DEPRECATED: See UninitializedNode.

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
getEnclosingCallable

INTERNAL: Do not use.

from InstructionNode
getFunction

Gets the function to which this node belongs, if any.

from InstructionNode
getInstruction

Gets the instruction corresponding to this node.

from InstructionNode
getLocation

Gets the location of this element.

from InstructionNode
getType

Gets the type of this node.

from InstructionNode
getTypeBound

Gets an upper bound on the type of this node.

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.
