Table
OpenMaple representation of a Table
Description
Method Summary
The com.maplesoft.openmaple.Table class represents a Maple table.
Table publicly inherits from Indexable; therefore, it provides all the member functions from the Indexable and Algebraic classes in addition to those listed here.
The Table class implements the java.util.Map interface with Algebraic key and value types.
To create a Table call newTable. The new Table will be empty.
The following methods are defined on Table objects:
void assign( Algebraic index, Algebraic val ) throws MapleException
assign places val into the Table with key index.
Algebraic select( Algebraic index ) throws MapleException
select returns the value associated with key index.
boolean has( Algebraic index ) throws MapleException
has returns true if the Table contains data associated with key index.
List indexEntryPairs( ) throws MapleException
indexEntryPairs returns a List of Relation objects corresponding to key/value pairs in the Table.
void unassign( Algebraic index ) throws MapleException
unassign removes the data associated with index from the Table.
The Table class also includes the following methods which implement the java.util.Map interface:
void clear( )
clear removes all data from the Table.
boolean containsKey( Object key )
containsKey returns true if key is an Algebraic and the Table contains a key identical to key.
This is similar to has except that it accepts an arbitrary Object and does not throw a MapleException.
boolean containsValue( Object value )
containsValue returns true if value is an Algebraic and the Table contains a value identical to value.
This is similar to member except that it accepts an arbitrary Object and does not throw a MapleException.
java.util.Set<Map.Entry<Algebraic,Algebraic>> entrySet( )
entrySet returns a java.util.Set view of the key/value pairs in the Table.
Algebraic get( Object key )
get returns the value associated with key key.
This is similar to select except that it accepts an arbitrary Object and does not throw a MapleException.
java.util.Set<Algebraic> keySet( )
keySet returns a java.util.Set view of the keys in the Table.
Algebraic put( Algebraic key, Algebraic value )
put assigns the value value into in the Table with key key.
This is similar to assign except that it does not throw a MapleException.
Algebraic putAll( Map<? extends Algebraic, ? extends Algebraic> m )
putAll puts each of the mappings from the specified map into the Table.
void remove( Algebraic index )
remove removes the data associated with index from the Table.
This is identical to unassign except that it does not throw a MapleException.
java.util.Collection<Algebraic> values( )
values returns a java.util.Collection view of the values contained in the Table.
