Method Detail

compile

public static java.util.List<ClassInfo> compile(java.util.List<java.lang.String> srcCodes)
                                         throws java.io.IOException

Given a list of file-scope java code (equivalent to a .java file, including package and import declarations), compile() invokes javac to compile them, produce classfiles and return a list of pairs. compile() dumps the source strings into their respective files, has javac compile them, then reads back the equivalent class files. The name of the source file is gleaned from the string itself; a string containing "public class Foo" is stored in tmpDir/Foo.java (where tmpDir is a temporary directory that's deleted after the compilation), and if no public class or interface is found, the name of the first class in the string is used. Note that the list of returned classes may be larger than list of sources Note: the java compiler api is ill-defined and this class should not be considered production. specifically, the classpath appears to depend on the execution environment, eg command line maven vs IDE vs the java command line

Parameters:

srcCodes - . List of strings.

Returns:

List. className is fully qualified, and byte[] contains the bytecode of the class.

Throws:

java.io.IOException

getClassPath

public static Javac.ClassPath getClassPath(java.lang.Class start,
                                           java.lang.ClassLoader end)

get the class path comprising the paths of URL class loaders ancestors

Parameters:

start - start with the class loader that loaded this object, or null for this method's class

end - the last classloader to consider, or null to include everything up to but not including the system class loader

Returns:

the URLs
