Class SizedString

java.lang.Object

overit.geocall.util.SizedString

public class SizedString
extends Object

This class implements a fixed length string filled with a character or a string that is named "base". The "base" can be overwritten partly or totally by a string, which can be inserted in any position. To implement this class we use the StringBuffer; This class includes two constructors: one to create the "base" with a single character and one with a string. Furthermore the method to print the result is overwritten.

Constructor	Description
SizedString(String s, char c, int dim, int pos)	The constructor to create the "base" string of size equal to the parameter passed and filled with a same character. The "base" string is overwritten by a string that can be placed in any index of the string.
SizedString(String s, String base, int pos)	The constructor to create the "base" string using the string passed as second parameter. The "base" string is overwritten by a string that can be placed in any index of the string.

Constructor Details

SizedString

public SizedString(String s,
 char c,
 int dim,
 int pos)

The constructor to create the "base" string of size equal to the parameter passed and filled with a same character.
The "base" string is overwritten by a string that can be placed in any index of the string. If overwriting exceeds the length of the "base" string, it is truncated.

Examples to clarify the use of the last parameter indicating the position of the string to be used in overwriting:

Examples

new SizedString("****", '1', 10, 0)	"****111111"
new SizedString("****", '1', 10, 9)	"111111111*"
new SizedString("****", '1', 10, -1)	"111111****"
new SizedString("****", '1', 10, -10)	"*111111111"

Parameters:

s - The string to use to overwrite the "base"

c - The character to use to fill the "base"

dim - The length of the "base"

pos - The index to position the string to be used in overwriting. It can be positive or negative. If it is positive, the starting index is indicated (where to start the string from the first character of the "base" the position to indicate is "0", instead to make it start from the last character the position is "length-1"). If it is negative, the index of the string end is indicated (where to end the string at the first character of the "base" the position to indicate is "-length", insted to make it end from the last character th position is "-1").

SizedString

public SizedString(String s,
 String base,
 int pos)

The constructor to create the "base" string using the string passed as second parameter.
The "base" string is overwritten by a string that can be placed in any index of the string. If overwriting exceeds the length of the "base" string, it is truncated.

Examples to clarify the use of the last parameter indicating the position of the string to be used in overwriting:

Examples

new SizedString("****", "0123456789", 10, 0)	"****456789"
new SizedString("****", "0123456789", 10, 9)	"012345678*"
new SizedString("****", "0123456789", 10, -1)	"012345****"
new SizedString("****", "0123456789", 10, -10)	"*123456789"

Parameters:

s - The string to use to overwrite the "base"

base - The string to use as "base"

pos - The index to position the string to be used in overwriting. It can be positive or negative. If it is positive, the starting index is indicated (where to start the string from the first character of the "base" the position to indicate is "0", instead to make it start from the last character the position is "length-1"). If it is negative, the index of the string end is indicated (where to end the string at the first character of the "base" the position to indicate is "-length", insted to make it end from the last character th position is "-1").
