Class Writers::FileWriter

A DataFlow::CallNode that reads data from the filesystem using the IO or File classes. For example, the write and puts calls in:

# writes the string `hello world` to the file `foo.txt`
IO.write("foo.txt", "hello world")

# appends the string `hello again\n` to the file `foo.txt`
File.new("foo.txt", "a").puts("hello again")

Predicates

getADataNode	Gets a node that represents data written to the file system by this access.
getAPathArgument	Gets an argument to this file system access that is interpreted as a path.

Inherited predicates

asCallable	Gets the callable corresponding to this block, lambda expression, or call to `proc` or `lambda`.	from Node
asExpr	Gets the expression corresponding to this node, if any.	from Node
asParameter	Gets the parameter corresponding to this node, if any.	from Node
backtrack	Gets a node that may flow into this one using one heap and/or interprocedural step.	from LocalSourceNode
backtrack	Starts backtracking from this node using API graphs.	from Node
flowsTo	Holds if this `LocalSourceNode` can flow to `nodeTo` in one or more local flow steps.	from LocalSourceNode
getADataNodeImpl	Gets a node representing the data read or written by this call	from IOOrFileWriteMethodCall

getALocalUse	Gets a node to which data may flow from this node in zero or more local data-flow steps.	from LocalSourceNode
getAMethodCall	Gets a method call where this node flows to the receiver.	from LocalSourceNode
getAMethodCall	Gets a call to a method named `name`, where this node flows to the receiver.	from LocalSourceNode
getAPathArgumentImpl		from IOOrFileMethodCall
getAPredecessor	Gets a data flow node from which data may flow to this node in one local step.	from Node

getATarget	Gets a potential target of this call, if any.	from CallNode
getAnAttributeRead	Gets a call `obj.name` with no arguments, where this node flows to `obj`.	from LocalSourceNode
getAnAttributeWriteValue	Gets a value assigned to `name` on this object, such as the `x` in `obj.name = x`.	from LocalSourceNode
getAnElementRead	Gets an access to an element on this node, such as `obj[key]`.	from LocalSourceNode
getAnElementRead	Gets an access to the element `key` on this node, such as `obj[:key]`.	from LocalSourceNode
getAnElementWriteValue	Gets a value stored as an element on this node, such as the `x` in `obj[key] = x`.	from LocalSourceNode
getAnElementWriteValue	Gets the `x` in `obj[key] = x`, where this node flows to `obj`.	from LocalSourceNode
getApi	Gets the API used to perform this call, either “IO” or “File”	from IOOrFileWriteMethodCall
getArgument	Gets the data-flow node corresponding to the `n`th argument of the call corresponding to this data-flow node	from CallNode
getBlock	Gets the block of this call.	from CallNode
getConstantValue	Gets the constant value of this expression, if any.	from Node
getEnclosingMethod	Gets the enclosing method, if any.	from Node
getExprNode	Gets the expression corresponding to this node.	from ExprNode
getKeywordArgument	Gets the data-flow node corresponding to the named argument of the call corresponding to this data-flow node	from CallNode
getKeywordArgumentIncludeHashArgument	Gets the data-flow node corresponding to the named argument of the call corresponding to this data-flow node, also including values passed with (pre Ruby 2.0) hash arguments.	from CallNode
getLocation	Gets the location of this node.	from Node
getMethodName	Gets the name of the method called by the method call (if any) corresponding to this data-flow node	from CallNode
getNumberOfArguments	Gets the number of arguments of this call.	from CallNode
getPositionalArgument	Gets the `n`th positional argument of this call. Unlike `getArgument`, this excludes keyword arguments.	from CallNode
getReceiver	Gets the data-flow node corresponding to the receiver of the call corresponding to this data-flow node	from CallNode
getReceiverKind	Gets a string representation of the receiver kind, either “class” or “instance”.	from IOOrFileWriteMethodCall
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
isSuperCall	Holds if this is a `super` call.	from CallNode
spawnsSubprocess	Holds if this call appears to read/write from/to a spawned subprocess, rather than to/from a file.	from IOOrFileMethodCall
toString	Gets a textual representation of this node.	from Node
track	Starts tracking this node forward using API graphs.	from LocalSourceNode
track	Gets a node that this node may flow to using one heap and/or interprocedural step.	from LocalSourceNode
