Class JGrep.JGrepIClassLoader

java.lang.Object

org.codehaus.janino.IClassLoader

org.codehaus.janino.tools.JGrep.JGrepIClassLoader

Enclosing class:

JGrep

private class JGrep.JGrepIClassLoader
extends IClassLoader

A specialized IClassLoader that loads IClasses from the following sources:

1. An already-parsed compilation unit
2. A class file in the output directory (if existant and younger than source file)
3. A source file in any of the source path directories
4. The parent class loader

Notice that the JGrep.JGrepIClassLoader is an inner class of JGrep and heavily uses JGrep's members.

public JGrepIClassLoader(IClassLoader optionalParentIClassLoader)

Parameters:

optionalParentIClassLoader - The IClassLoader through which IClasses are to be loaded

Method Detail

findIClass

protected IClass findIClass(java.lang.String type)

Description copied from class: IClassLoader

Find a new IClass by descriptor; return null if a class for that descriptor could not be found.

Similar ClassLoader.findClass(java.lang.String), this method must

• Get an IClass object from somewhere for the given type
• Call IClassLoader.defineIClass(IClass) with that IClass object as the argument
• Return the IClass object

The format of a descriptor is defined in JVMS 4.3.2. Typical descriptors are:

• I (Integer)
• Lpkg1/pkg2/Cls; (Class declared in package)
• Lpkg1/pkg2/Outer$Inner; Member class

Notice that this method is never called for array types.

Notice that this method is never called from more than one thread at a time. In other words, implementations of this method need not be synchronized.

Specified by:

findIClass in class IClassLoader

Parameters:

type - Field descriptor of the to load, e.g. "Lpkg1/pkg2/Outer$Inner;"

Returns:

null if a class with that descriptor could not be found
