Method Detail

trim

public static java.util.Collection<java.lang.String> trim(java.util.Collection<java.lang.String> strings)

unquoteDatabaseName

public static java.lang.String unquoteDatabaseName(java.lang.String s)

removeBrackets

public static java.lang.String removeBrackets(java.lang.String s)

join

public static java.lang.String join(char delimiter,
                                    java.lang.String... strings)

Join a list of strings with a delimiter. If the first string is empty, its delimiter is included. No delimiters are included for subsequent empty strings.

unquote

public static java.lang.String unquote(java.lang.String string)

Remove leading and trailing single-, double-, or back-quotes, if any.

fixInternalClassName

public static java.lang.String fixInternalClassName(java.lang.String className)

We use shadow jar to repackage third party libraries. The side effect is that it make it hard to reference these libraries in our instrumentation because the class names get rewritten - org/apache/commons/ClassName becomes com/newrelic/agent/deps/org/apache/commons/ClassName. This method rewrites these repackaged class names to their original package.

replaceDotHyphenWithUnderscore

public static java.lang.String replaceDotHyphenWithUnderscore(java.lang.String string)

Replaces occurrences of '.' and '-' within the string with the underscore character ('_'). This optimizes the fast path of config reading.

Parameters:

string - The string to replace

Returns:

String value with dots and hyphens replaced with underscore character.

obfuscate

public static java.lang.String obfuscate(java.lang.String target)

Obfuscate the supplied String. If the String is null or less than 4 characters, return the original String. Otherwise, return the first character + "***" + the last character.

Parameters:

target - The String to obfuscate

Returns:

the obfuscated String or the original String if it's null or less than 4 characters
