The HelpCallBacks interface provides the functionality required to access the text of a help page.

The EngineCallBacks interface provides the functionality required to transfer general information between the user and Maple evaluation engine, for example, interrupt handling and warning, error, and status messages.

The Engine class is used to start, restart, and stop the Maple session as well as evaluate Maple statements and create new Maple data structures.

The Algebraic class is the parent class of all the classes that represent Maple objects.  Its member functions provide access to all the basic functions that can be performed on an object.

The Numeric class represents numeric objects (integers, fractions, and floats).  The Numeric class has member functions to convert the Maple object to the Java native types.

The ComplexNumeric class represents complex numbers.  Conceptually, a ComplexNumeric object contains two Numeric objects: its real part and its imaginary part.

The Name class represents a Maple name. Name publicly inherits from Algebraic.

The Procedure class represents a procedure. Member functions allow for evaluating the procedure.

The Relation class represents a relation.  Member functions allow for returning the left-hand or right-hand side of the relation or evaluating it to a true/false value.

The Indexable class is the parent class of all the classes that represent Maple collections.  Its member functions provide access to the basic functions that can be performed on a collection, such as querying its size and testing for membership.

The Expseq class represents an expression sequence.  Member functions allow for indexing into the expression sequence and returning its length.

The List class represents a list.  Member functions allow for indexing into the list and returning its length.

The Set class represents a set.  Member functions allow for indexing into the set and returning its length.

The Table class represents a table.  Data can be inserted and removed from the table and a table can be searched for a particular element.

The RTable class represents an rtable. Datatype specific rtables are represented by sub-classes of RTable.  These sub-classes have datatype specific functions.  The RTable member functions perform operations applicable to any rtable.

The AlgebraicRTable class represents an rtable of type anything.  It allows access to individual elements of the rtable as Algebraic objects.

The ByteRTable class represents an rtable of type ${\mathrm{integer}}_1$.  It allows access to individual elements of the rtable as Java bytes.

The ComplexDoubleRTable class represents an rtable of type ${\mathrm{complex}}_8$. It allows access to individual elements of the rtable as pairs of Java doubles.

The ComplexNumericRTable class represents an rtable of type $\mathrm{complex}\left(\mathrm{sfloat}\right)$.  It allows access to individual elements of the rtable as ComplexNumeric objects.

The DoubleRTable class represents an rtable of type ${\mathrm{float}}_8$.  It allows access to individual elements of the rtable as Java doubles.

The FloatRTable class represents an rtable of type ${\mathrm{float}}_4$.  It allows access to individual elements of the rtable as Java floats.

The IntRTable class represents an rtable of type ${\mathrm{integer}}_4$.  It allows access to individual elements of the rtable as Java integers.

The LongRTable class represents an rtable of type ${\mathrm{integer}}_8$.  It allows access to individual elements of the rtable as Java longs.

The NumericRTable class represents an rtable of type $\mathrm{sfloat}$.  It allows access to individual elements of the rtable as Numeric objects.

The ShortRTable class represents an rtable of type ${\mathrm{integer}}_2$.  It allows access to individual elements of the rtable as Numeric objects.

The MapleException class is used when errors are raised within Java Open Maple. See also the ?MapleException class constructor help page.

The HelpCallBacksDefault provides a basic implementation of the HelpCallBacks interface.  This class can be used directly or it can be sub-classed to override the member functions.

The EngineCallBacksDefault provides a basic implementation of the EngineCallBacks interface.  This class can be used directly or it can be sub-classed to override the member functions.

The MString represents a Maple string.  This class provides conversion from Maple strings to Java strings.
