PackageCompilationData

public PackageCompilationData(java.lang.ClassLoader parentClassLoader)

Method Detail

writeExternal

public void writeExternal(java.io.ObjectOutput stream)
                   throws java.io.IOException

Handles the write serialization of the PackageCompilationData. Patterns in Rules may reference generated data which cannot be serialized by default methods. The PackageCompilationData holds a reference to the generated bytecode. The generated bytecode must be restored before any Rules.

Specified by:

writeExternal in interface java.io.Externalizable

Throws:

java.io.IOException

---

readExternal

public void readExternal(java.io.ObjectInput stream)
                  throws java.io.IOException,
                         java.lang.ClassNotFoundException

Handles the read serialization of the PackageCompilationData. Patterns in Rules may reference generated data which cannot be serialized by default methods. The PackageCompilationData holds a reference to the generated bytecode; which must be restored before any Rules. A custom ObjectInputStream, able to resolve classes against the bytecode, is used to restore the Rules.

Specified by:

readExternal in interface java.io.Externalizable

Throws:

java.io.IOException

java.lang.ClassNotFoundException

---

getClassLoader

public java.lang.ClassLoader getClassLoader()

---

read

public byte[] read(java.lang.String resourceName)

---

write

public void write(java.lang.String resourceName,
                  byte[] clazzData)
           throws RuntimeDroolsException

Throws:

RuntimeDroolsException

---

remove

public void remove(java.lang.String resourceName)
            throws RuntimeDroolsException

Throws:

RuntimeDroolsException

---

list

public java.lang.String[] list()

---

reload

public void reload()
            throws RuntimeDroolsException

This class drops the classLoader and reloads it. During this process it must re-wire all the invokeables.

Throws:

CheckedDroolsException

RuntimeDroolsException

---

clear

public void clear()

---

wire

public void wire(java.lang.String className)
          throws java.lang.ClassNotFoundException,

Throws:

java.lang.ClassNotFoundException

java.lang.InstantiationException

java.lang.IllegalAccessException

---

wire

public void wire(java.lang.String className,
                 java.lang.Object invoker)
          throws java.lang.ClassNotFoundException,
                 java.lang.InstantiationException,
                 java.lang.IllegalAccessException

Throws:

java.lang.ClassNotFoundException

---

getInvokers

public java.util.Map getInvokers()

---
