Method Detail

getObjectCode

public byte getObjectCode()

Description copied from class: oracle.javatools.assembly.ObjectFactory

Implementation-specific method for fetching a constant defining this object. This object code is inserted into the binary data (i.e., at the beginning) to uniquely tag this object in the binary data - this is used for verification upon reassembly from the binary data. Implementations are encouraged to return their own unique code here.

Implementations should not change the object code for their objects between binary data versions, but should use the getDisassemblyVersion() instead for returning versioning information.

Overrides:

getObjectCode in class oracle.javatools.assembly.ObjectFactory

Returns:

a unique object code for tagging this object in the binary data

assembleImpl

public java.lang.Object assembleImpl(java.io.DataInput input)
                              throws java.io.IOException,
                                     oracle.javatools.assembly.AssemblyException

Description copied from class: oracle.javatools.assembly.ObjectFactory

Implementation-specific method for assembling an Object from the input stream. The returned object cannot be null.

Specified by:

assembleImpl in class oracle.javatools.assembly.ObjectFactory

Parameters:

input - the input stream to assemble from

Returns:

the non-null object assembled

Throws:

java.io.IOException - if an error occurred reading from the stream

oracle.javatools.assembly.AssemblyException - if assembly failed

disassembleImpl

public void disassembleImpl(java.lang.Object object,
                            java.io.DataOutput output)
                     throws java.io.IOException,
                            java.lang.ClassCastException,
                            oracle.javatools.assembly.AssemblyException

Description copied from class: oracle.javatools.assembly.ObjectFactory

Implementation-specific method for disassembling a non-null Object to the output stream.

Specified by:

disassembleImpl in class oracle.javatools.assembly.ObjectFactory

Parameters:

object - the non-null object to disassemble

output - the output stream to disassemble to

Throws:

java.io.IOException - if an error occurred writing to stream

java.lang.ClassCastException - if the object is not of type expected by this factory

oracle.javatools.assembly.AssemblyException - if disassembly failed
