Node-Type Steps

Node-Type Steps are CPGQL Steps that traverse nodes based on their type.

Overview #

Step	Description
all	Visits all nodes in the Code Property Graph
block	Visits BLOCK nodes
call	Visits CALL nodes, represent call-sites
comment	Visits COMMENT nodes, COMMENT nodes exist only for source-based Code Property Graphs
file	Visits FILE nodes, in source-based Code Property Graphs, FILE nodes will point both to the actual source code files of the program under analysis and paths to the referenced files from the standard library, for IR-based Code Property Graphs, the nodes representing source code files will not exist
identifier	Visits IDENTIFIER nodes; e.g. occurrences of local variables or class members in method bodies
literal	Visits LITERAL nodes; e.g. numbers or strings
local	Visits LOCAL nodes; represent local variable
member	Visits MEMBER nodes; MEMBER nodes refer to members of complex types like classes or structs
metaData	Visits the META_DATA node
method	Visits METHOD nodes
methodRef	Visits METHOD_REF nodes
methodReturn	Visits METHOD_RETURN nodes; all formal return parameters
modifier	Visits MODIFIER nodes; e.g. public, private, static
namespace	Visits NAMESPACE nodes
namespaceBlock	Visits NAMESPACE_BLOCK nodes
parameter	Visits PARAMETER nodes
returns	Visits RETURN nodes
typeDecl	Visits TYPE_DECL nodes
tag	Visits TAG nodes
typ	Visits TYPE nodes

all #

The all Node-Type Step represents a traversal which visits all nodes of a Code Property Graph. It supports the two only Property Directives which are common to all Node-Type Steps, id and label.

Supported Property Directives

Property Directive	Return Type	Description
id	int	Unique node identifier
label	string	Returns the value of the LABEL property which represents the node type

Supported Node Type Steps

Node Type Step	Description
file	Visits FILE nodes attached to all nodes in the graph
tag	Visits TAG nodes attached to all nodes in the graph

Supported Complex Steps

None.
