Predicates

accessesGlobal	Holds if this data flow node accesses the global variable `g`, either directly or through the `window` object.
analyze	Gets type inference results for this data flow node.
asExpr	Gets the expression corresponding to this data flow node, if any.
getABoundFunctionValue	Gets a function value that may reach this node, possibly derived from a partial function invocation.
getAFunctionValue	Gets a function value that may reach this node.
getAFunctionValue	Gets a function value that may reach this node with the given `imprecision` level.
getALocalSource	Gets a source node from which data may flow to this node in zero or more local steps.
getAPredecessor	Gets a data flow node from which data may flow to this node in one local step.
getASuccessor	Gets a data flow node to which data may flow from this node in one local step.
getAstNode	Gets the AST node corresponding to this data flow node, if any.
getBasicBlock	Gets the basic block to which this node belongs.
getContainer	Gets the container in which this node occurs.
getEnclosingExpr	Gets the expression enclosing this data flow node. In most cases the result is the same as `asExpr()`, however this method additionally includes the `InvokeExpr` corresponding to reflective calls.
getEndColumn	Gets the end column of this data flow node.
getEndLine	Gets the end line of this data flow node.
getFile	Gets the file this data flow node comes from.
getImmediatePredecessor	Gets the immediate predecessor of this node, if any.
getIntValue	Gets the integer value of this node, if it is an integer constant.
getStartColumn	Gets the start column of this data flow node.
getStartLine	Gets the start line of this data flow node.
getStringValue	Gets the string value of this node, if it is a string literal or constant string concatenation.
getTopLevel	Gets the toplevel in which this node occurs.
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.
hasUnderlyingType	Holds if this node is annotated with the given named type, or is declared as a subtype thereof, or is a union or intersection containing such a type.
hasUnderlyingType	Holds if this node is annotated with the given named type, or is declared as a subtype thereof, or is a union or intersection containing such a type.
isIncomplete	Holds if the flow information for this node is incomplete.
mayHaveBooleanValue	Holds if this node may evaluate to the Boolean value `b`.
mayHaveStringValue	Holds if this node may evaluate to the string `s`, possibly through local data flow.
mayReferToParameter	DEPRECATED: Use `DataFlow::ParameterNode::flowsTo()` instead. Holds if this expression may refer to the initial value of parameter `p`.
toString	Gets a textual representation of this element.
