Class math.alg.PowerSeries.Term 

java.lang.Object
   |
   +----math.alg.PowerSeries.Term
public class Term
extends Object
Represents terms of a Non-commutative power series. Terms consist of an integer coefficient and a monomial.

Constructor Index

o Term(NCseries)
Creates a new term for a NCseries of given type.

Method Index

o appendFactor(Factor)
Appends a Factor f to the monomial for this term.
o compare(Term, Term)
Compares two terms $t1$, $t2$: returns $-1$ if $t1 < t2$, 0 if they're equal, and 1 if $t1 > t2$.
o compare_to(Term)
Compares this term with term t: returns $-1$ if this $< t$, 0 if they're equal, and 1 if this $> t$.
o getCoeff()
Gets the coefficient of this term.
o getMonomial()
Returns the monomial of this term.
o getTotalDegree()
Gets the total degree of this term.
o insertFactor(Factor, int)
Inserts a Factor f into the monomial for this term at the given position.
o reduce(Term)
Reduces the given term, so that adjacent similar variables are coalesced.
o setCoeff(int)
Sets the coefficient of this term.
o setMonomial(Vector)
Sets the monomial of this term to the given monomial.
o times(Term)
Returns the product (non-commutative!) of this term with the given term.
o toString()
Formats this term as a string and returns the result.

Constructors

o Term 
 public Term(NCseries parent)
Creates a new term for a NCseries of given type.

Methods

o insertFactor 
 public void insertFactor(Factor f,
                          int posn)
Inserts a Factor f into the monomial for this term at the given position.

o getMonomial 
 public Vector getMonomial()
Returns the monomial of this term.

o setMonomial 
 public void setMonomial(Vector new_monomial)
Sets the monomial of this term to the given monomial.

o appendFactor 
 public void appendFactor(Factor f)
Appends a Factor f to the monomial for this term.

o getTotalDegree 
 public int getTotalDegree()
Gets the total degree of this term.

o getCoeff 
 public int getCoeff()
Gets the coefficient of this term.

o setCoeff 
 public void setCoeff(int value)
Sets the coefficient of this term.

o compare_to 
 public int compare_to(Term t)
Compares this term with term t: returns $-1$ if this $< t$, 0 if they're equal, and 1 if this $> t$.

o reduce 
 public void reduce(Term t)
Reduces the given term, so that adjacent similar variables are coalesced.

o times 
 public Term times(Term t2)
Returns the product (non-commutative!) of this term with the given term.

o toString 
 public String toString()
Formats this term as a string and returns the result. Note: This prints the coefficient, but not the sign of the coefficient, to make things easier for higher text formating routines.

Overrides:
toString in class Object
o compare 
 public static int compare(Term t1,
                           Term t2)
Compares two terms $t1$, $t2$: returns $-1$ if $t1 < t2$, 0 if they're equal, and 1 if $t1 > t2$.
