jreflection: Simple helper functions for Java reflection
Description
.jconstructors returns a character vector with all constructors for
a given class or object.
.jmethods returns a character vector with all methods for
a given class or object.
.jfields returns a character vector with all fileds (aka attributes) for a given class or object.
Usage
.jconstructors(o)
.jmethods(o, name = NULL)
.jfields(o)
Arguments
o
Name of a class (either notation is fine) or an object whose
class will be queried
name
Name of the method to look for. May contain regular
expressions except for ^$.
Value
Returns a character vector. Each entry corresponds to
toString() call on the Constructor resp. Method resp. Field
object.
Details
There first two functions are intended to help with finding correct
signatures for methods and constructors. Since the low-level API in rJava doesn't use reflection automatically, it is necessary to provide a proper
signature. That is somewhat easier using the above methods.
