Method Detail

prettyPrint

public static String prettyPrint(String in,
                 int lineLength,
                 String delim)

Method that attempts to break a string up into lines no longer than the specified line length.

The string is assumed to consist of tokens separated by a delimeter. The default delimiter is a space. If the last token to be added to a line exceeds the specified line length, it is written on the next line so actual line length is approximate given the specified line length and the length of tokens in the string.

Parameters:

in - The input string to be split into lines.

lineLength - The maximum length of each line.

delim - The character delimiter separating each token in the input string; if null, defaults to the space character.

Returns:

A string split into multiple lines whose lenght is less than the specified length. Actual length is approximate depending on line length, token size, and how many complete tokens will fit into the specified line length.

splitAndIndent

public static String splitAndIndent(String str,
                    int indent,
                    int numChars)

Method that attempts to break a string up into lines no longer than the specified line length.

The string is assumed to a large chunk of undifferentiated text such as base 64 encoded binary data.

Parameters:

str - The input string to be split into lines.

indent - The number of spaces to insert at the start of each line.

numChars - The maximum length of each line (not counting the indent spaces).

Returns:

A string split into multiple indented lines whose length is less than the specified length + indent amount.
