Class StrArrayConverter  

java.lang.Object
  org.apache.commons.beanutils.converters.AbstractArrayConverter
      com.puppycrawl.tools.checkstyle.api.StrArrayConverter

All Implemented Interfaces:

org.apache.commons.beanutils.Converter

---

final class StrArrayConverter

extends org.apache.commons.beanutils.converters.AbstractArrayConverter

Standard Converter implementation that converts an incoming String into an array of String. On a conversion failure, returns a specified default value or throws a ConversionException depending on how this instance is constructed.

Hacked from http://cvs.apache.org/viewcvs/jakarta-commons/beanutils/src/java/org/apache/commons/beanutils/converters/StringArrayConverter.java because that implementation fails to convert array of tokens with elements containing an underscore, "_" :(

Parse an incoming String of the form similar to an array initializer in the Java language into a List individual Strings for each element, according to the following rules.

• The string must have matching '{' and '}' delimiters around a comma-delimited list of values.
• Whitespace before and after each element is stripped.
• If an element is itself delimited by matching single or double quotes, the usual rules for interpreting a quoted String apply.
