Constructor Detail

EvaluatorOutput

public EvaluatorOutput(Evaluator eval)

Method Detail

make

public boolean make()

display

public boolean display(Task obj)

A textual representation of the task (expression, result, etc) to the output area.

Specified by:

display in interface TaskDisplayFilter

display

public boolean display(java.lang.Object el,
                       long num)

Description copied from interface: ObjectDisplayFilter

Display the specified object in a suitable manner assuming that the object is nested within the top-level object being displayed at level level.

Specified by:

display in interface ObjectDisplayFilter

display

public boolean display(java.lang.Object el)

Description copied from interface: ObjectDisplayFilter

Display the given object, assuming it is the top-level object being displayed.

Specified by:

display in interface ObjectDisplayFilter

Following copied from interface: org.omegahat.Environment.IO.ObjectDisplayFilter

See Also:

ObjectDisplayFilter.display(java.lang.Object, long)

writer

public java.io.Writer writer()

Description copied from interface: ObjectDisplayFilter

Obtain the output stream to which the data can be written.

Specified by:

writer in interface ObjectDisplayFilter

toWriter

public java.io.Writer toWriter(java.lang.Object obj)

Description copied from interface: ObjectDisplayFilter

Not sure what I intended for this - write the object to the output stream using the toString() method, or convert the object to the writer and register it.

Specified by:

toWriter in interface ObjectDisplayFilter

toString

public java.lang.String toString(java.lang.Object o)

Description copied from interface: ObjectDisplayFilter

Convert the given object to a String. This is used by other objects when they take over the output of their contents and want to use the services of this filters formatting but change the overall layout of the components, not their content display. For example, we can display the contents of a table by converting each cell to a string and then managing the specification of the table. Alternatively, to embed an object within an HTML link to allow users to re-evaluate the associated expression, or bring up a plot or editor window, we would obtain the representation of the element using this method and then insert it into the link as part of the output stream.

Specified by:

toString in interface ObjectDisplayFilter

createDisplayAttributes

public boolean createDisplayAttributes()
