Method Detail

getEscapedStringOf

public static java.lang.String getEscapedStringOf(java.lang.String fromString)

Returns fromString, but with non-isalpha() characters printed as '\\unnnn'. Used by SootClass to generate output.

getQuotedStringOf

public static java.lang.String getQuotedStringOf(java.lang.String fromString)

Returns fromString, but with certain characters printed as if they were in a Java string literal. Used by StringConstant.toString()

getUnicodeStringFromChar

public static java.lang.String getUnicodeStringFromChar(char ch)

Returns a String containing the escaped \\unnnn representation for ch.

getUnEscapedStringOf

public static java.lang.String getUnEscapedStringOf(java.lang.String str)

Returns a String de-escaping the \\unnnn representation for any escaped characters in the string.

getCFormatChar

public static char getCFormatChar(char c)

Returns the canonical C-string representation of c.

replaceAll

public static java.lang.String replaceAll(java.lang.String orig,
                                          java.lang.String toBeReplaced,
                                          java.lang.String replacement)

Replaces all occurrences of the given substring with the given replacement string.

Parameters:

orig - The string in which all occurrences of the substring are to be replaced.

toBeReplaced - The substring which is to be replaced.

replacment - The string which is to replace toBeReplaced.

Returns:

The resulting String.

This method provides a facility similar to the String.replaceAll() method available in Java 1.4, except that it can only replace substrings rather than regular expressions. So if Soot ever abandons compatibility with pre-1.4 definitions of the Java API, it can also abandon replaceAllIn().
