Method Detail

readObject

public OMObject readObject()
                    throws java.io.IOException

Read an OpenMath object.

1. If we are a document then get the nodelist that contains an OMOBJ. Take the first of the list and read that object.

2. Or if we are a document fragment assume the first child is the OMObject.

3. Or just assume the node contains the OMObject.

Returns:

the OpenMath object.

Throws:

java.io.IOException - when a problem arises while reading.
