from Node
asInstruction

Gets the IR instruction corresponding to this node, if any.

from InstructionNode
getAPredecessor

Gets a data-flow node from which data may flow to this node in one (intra-procedural) step.

from Node
getASuccessor

Gets a data-flow node to which data may flow from this node in one (intra-procedural) step.

from Node
getBasicBlock

Gets the basic block to which this data-flow node belongs, if any.

from Node
getBoolValue

Gets the Boolean value this data-flow node contains, if any.

from Node
getCallable

Gets the callable that this parameter belongs to.

from ParameterNode
getEnclosingCallable

INTERNAL: Use getRoot() instead.

from Node

Gets the end column of the location of this node.

from Node
getEndLine

Gets the end line of the location of this node.

from Node
getExactValue

getFloatValue

Gets the floating-point value this data-flow node contains, if any.

from Node
getIntValue

Gets the integer value this data-flow node contains, if any.

from Node
getLocation

Gets the location of this node.

from Node
getNodeKind

Gets a textual representation of the kind of this data-flow node.

from InstructionNode
getNumericValue

Gets either getFloatValue or getIntValue.

from Node
getPosition

Gets this parameter’s position.

from ParameterNode
getRoot
