public class StringTable
extends Object

The StringTable class easy handling of string tables, especially creating tables from strings and lists. The table constructed is guaranteed to be complete in that each row has the exact same number of columns and each table cell is guaranteed to not be null.

Method Summary

static StringTable	fromString(String srcString, String delims)	Constructor does the hard work converting the string Creates a new table from the string, where the fields are separated by any one of the delimiters.
static StringTable	fromString(String srcString, String delims, boolean preserveEmptyRows)	Constructor does the hard work converting the string Creates a new table from the string, where the fields are separated by any one of the delimiters.
int	getCols()	Returns the number of columns in the table.
int	getRows()	Returns the number of rows in the table.
String[][]	getTable()	Returns the string table created.

Method Detail

fromString

public static StringTable fromString(String srcString,
                                     String delims)

Constructor does the hard work converting the string Creates a new table from the string, where the fields are separated by any one of the delimiters. Consecutive delimiters define empty field values. The table rows in the string are separated by either CR, LF or both. So neither CR nor LF may be used as a field delimiter.

The string is logically split on CR/LF to get the rows. Each row is then split on the delimiters to get the cells.

Any empty rows in the string table are preserved as empty rows in the resulting table.

Parameters:

srcString - The string from which to construct the table

delims - The delimiters for columns.

Returns:

The table from the string.

fromString

public static StringTable fromString(String srcString,
                                     String delims,
                                     boolean preserveEmptyRows)

Constructor does the hard work converting the string Creates a new table from the string, where the fields are separated by any one of the delimiters. Consecutive delimiters define empty field values. The table rows in the string are separated by either CR, LF or both. So neither CR nor LF may be used as a field delimiter.

The string is logically split on CR/LF to get the rows. Each row is then split on the delimiters to get the cells.

Parameters:

srcString - The string from which to construct the table

delims - The delimiters for columns.

preserveEmptyRows - If true empty rows in the input string are added as empty rows in the table. Otherwise empty rows in the input are ignored.

Returns:

The table from the string.

transpose

public StringTable transpose()

Transposes the table - cols will be rows and rows will be cols. The operation is that the table is mirrored on the diagonal from 0/0 to n/n.

getTable

public String[][] getTable()

Returns the string table created. This is the original table, so modifying entries in this object, also modifies the table. Especially modifying array elements of the first dimension may invalidate the class invariant, in that the table is not complete anymore. User beware.

Returns:

The string table

getRows

public int getRows()

Returns the number of rows in the table.

getCols

public int getCols()

Returns the number of columns in the table.
