public class SequenceFunctions

extends java.lang.Object

Class used with the addFunctionTable() method to provide "functions" for performing basic sequence operations.

Constructor Summary

SequenceFunctions()

Method Summary

static java.lang.Object[]	c(java.lang.Object[] a, java.lang.Object[] b) Specialized version of the more general method in VarSequenceFunctions, concatenates two arrays into a single array containing the elements of both in the order they are specified.
static java.lang.Object	cycle(java.lang.Object[] vals, int times) Replicates the specified array, repeating the sequence of elements times times, resulting in an array of length vals.length * times
static java.lang.Object	cycle(java.util.Vector vals, int times) Take the contents of a vector and repeat them in order for a total length of vals.size() * times
static java.lang.Object[]	rep(java.lang.Object obj, int length) repeat the specified object length times and return an array.
static java.lang.Object[]	rep(java.lang.Object obj, int length, boolean copy)

Method Detail

rep

public static java.lang.Object[] rep(java.lang.Object obj,
                                     int length)

repeat the specified object length times and return an array.

rep

public static java.lang.Object[] rep(java.lang.Object obj,
                                     int length,
                                     boolean copy)

cycle

public static java.lang.Object cycle(java.lang.Object[] vals,
                                     int times)

Replicates the specified array, repeating the sequence of elements times times, resulting in an array of length vals.length * times

Omegahat Example:

[]  o = new Object[]{1,"x"}
[]  cycle(o, 3)

1 
"x"
1
"x"
1
"x"

cycle

public static java.lang.Object cycle(java.util.Vector vals,
                                     int times)

Take the contents of a vector and repeat them in order for a total length of vals.size() * times

Omegahat Example:

v = util.Vector()
v[[0]] = 1
v[[1]] = "x"
cycle(v, 3)

[1, "x", 1, "x", 1, "x"]  // vector of length 6

c

public static java.lang.Object[] c(java.lang.Object[] a,
                                   java.lang.Object[] b)

Specialized version of the more general method in VarSequenceFunctions, concatenates two arrays into a single array containing the elements of both in the order they are specified.

a = new Object[]

Returns:

array containing the elements from the first argument followed by the elements from the second argument.
