    getArgument

    getEnclosingCallable

    INTERNAL: Do not use.

    getFunction

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

    hasAddressOperandAndIndirectionIndex

    Gets the underlying operand and the underlying indirection index.

    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
    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
    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
    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
    getLocation

    Gets the location of this element.

    from Node
    getLocationImpl

    INTERNAL: Do not use.

    from Node
    getType

    Gets the type of this node.

    from Node
    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 Node
    toString

    Gets a textual representation of this element.
