JavaDialectRuntimeData

public JavaDialectRuntimeData()

Method Detail

writeExternal

public void writeExternal(ObjectOutput stream)
                   throws 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 Externalizable

Throws:

IOException

readExternal

public void readExternal(ObjectInput stream)
                  throws IOException,
                         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 Externalizable

Throws:

IOException

ClassNotFoundException
