Reference Card

Step	Description
`all`	All nodes
`argument`	All arguments (actual parameters)
`call`	All call sites
`comment`	All comments (only source-based CPGs)
`file`	All source files
`identifier`	All identifiers, e.g. occurrences of local variables or class members in method bodies
`literal`	All literals, e.g. numbers or strings
`local`	All local variables
`member`	All members of complex types, e.g. classes, structs
`metaData`	The meta data node
`method`	All methods
`methodRef`	All method references
`methodReturn`	All formal return paramters
`namespace`	All namespaces
`namespaceBlock`	All namespace blocks
`parameter`	All parameters
`returns`	All actual return parameters
`typeDecl`	All declarations of types
`tag`	All tags
`types`	All used types

Step	Description
`clone`	Create a deep copy of the traversal
`dedup`	Deduplicate results in a traveral
`map`	Transform the traversal by a given function
`sideEffect`	Extend the traversal with a side-effect step by applying a function

Step	Description
`and`	The and step is a filter with multiple and related filter traversals.
`filter`	Traversal proceeds for steps with non-empty returns for the provided `predicate`
`filterNot`	Traversal proceeds for steps with empty returns for the provided `predicate`
`where`	Keep nodes for which the provided `predicate` returns true
`whereNonEmpty`	Keep nodes for which the provided `predicate` returns a non-empty result
`or`	The or step is a filter with multiple or related filter traversals.

Step	Description
`repeat`	Repeat the given traversal. This step can be combined with the until and emit steps to provide a termination and emit criteria.
`until`	Termination criteria for a repeat step. If used before the repeat step it as "while" characteristics. If used after the repeat step it as "do-while" characteristics.
`times`	Modifier for repeat steps. Configure the amount of times the repeat traversal is executed.
`emit`	Emit is used with the repeat step to emit the elements of the repeatTraversal after each iteration of the repeat loop.

Step	Description
`callee`	List all nodes representing Call Graph callees of the traversed nodes
`caller`	List all nodes representing Call Graph callers of the traversed nodes
`callIn`	List all nodes representing Call Graph parent call-sites of the traversed nodes
`controlledBy`	Returns only those dataflows that are wrapped by a given AST control condition (>, <, =, etc.)
`dump`	Execute the traversal and return the CODE property with syntax highlighting
`dumpRaw`	Execute the traversal and return the CODE property without syntax highlighting
`inCall`	Lists all nodes representing surrounding Call Graph call-sites of the traversed nodes
`locations`	List of all locations nodes traversed in a given dataflow
`notControlledBy`	Returns only those flows that are NOT wrapped by a given AST control condition (>, <, =, etc.)
`passesNot`	Returns only those dataflows that DO NOT pass through a given function/condition as defined in predicate
`passes`	Returns only those dataflows that pass through a given function/condition as defined in predicate
`reachableBy`	Find if a given source node is reachable by a sink via a dataflow
`sink`	List of all nodes identified as potential sensitive sinks the natured of methods, literals, types etc. associated with them
`source`	List of all nodes identified as sensitive/attacker-controlled due to the natured of methods, literals, types etc. associated with them
`tagList`	Execute the traversal and return TAG nodes connected to each of the nodes

Directive	Description
`toList`	Execute the traversal and convert the result to a list
`l`	Shorthand for `toList`
`toJson`	Execute the traversal and convert the result to JSON
`toJsonPretty`	Execute the traversal and convert the result to prettified JSON
`p`	Execute the traversal and pretty print the results
`size`	Execute the traversal and return the size of the array of nodes

Ocular Query Component	Description
`help`	Print help based on the current element type

Directive	Description
`newTagNode`	Tag node with a specific name
`newTagNodePair`	Tag node with a specific name and value
`store`	Store changes in the current DiffGraph
