Class | Brakeman::FindCall |
In: |
lib/brakeman/processors/lib/find_call.rb
|
Parent: | Brakeman::BasicProcessor |
Finds method calls matching the given target(s).
#-- This should be deprecated --# #-- Do not use for new code --#
Targets/methods can be:
- nil: matches anything, including nothing - Empty array: matches nothing - Symbol: matches single target/method exactly - Array of symbols: matches against any of the symbols - Regular expression: matches the expression - Array of regular expressions: matches any of the expressions
If a target is also the name of a class, methods called on instances of that class will also be matched, in a very limited way. (Any methods called on Klass.new, basically. More useful when used in conjunction with AliasProcessor.)
Examples:
#To find any uses of this class: FindCall.new :FindCall, nil #Find system calls without a target FindCall.new [], [:system, :exec, :syscall] #Find all calls to length(), no matter the target FindCall.new nil, :length #Find all calls to sub, sub!, gsub, or gsub! FindCall.new nil, /^g?sub!?$/
Returns a list of results.
A result looks like:
s(:result, :ClassName, :method_name, s(:call, ...))
or
s(:result, :template_name, s(:call, ...))
Process the given source. Provide either class and method being searched or the template. These names are used when reporting results.
Use FindCall#matches to retrieve results.
