@Pierre, you’re correct, this method doesn’t show you the meta methods that are on every Object, the ones that most of the time I don’t find interesting. It also contains the static class meta methods that are added by the DefaultGroovyMethods class.

If you really want to see those methods as well, you can look at the metaMethods collection:

groovy> "foo".metaClass.metaMethods.name.sort().unique()
 
Result: [addShutdownHook, any, asType, bitwiseNegate, center, collect, contains, count, decodeBase64, denormalize, dump, each, eachLine, eachMatch, eachWithIndex, every, execute, find, findAll, findIndexOf, findIndexValues, findLastIndexOf, getAt, getChars, getMetaClass, getMetaPropertyValues, getProperties, grep, hasProperty, identity, inject, inspect, invokeMethod, is, isBigDecimal, isBigInteger, isCase, isDouble, isFloat, isInteger, isLong, isNumber, iterator, leftShift, matches, metaClass, minus, multiply, next, normalize, numberAwareCompareTo, padLeft, padRight, plus, previous, print, printf, println, putAt, readLines, replace, replaceAll, replaceFirst, respondsTo, reverse, setMetaClass, size, sleep, split, splitEachLine, sprintf, toBigDecimal, toBigInteger, toBoolean, toCharacter, toDouble, toFloat, toInteger, toList, toLong, toShort, toString, toURI, toURL, tokenize, use, with]

If you really want a full list of ALL methods, you can add the methods to the metaMethods and sort + unique that:

groovy> ("foo".metaClass.methods.name + "foo".metaClass.metaMethods.name).sort().unique()
 
Result: [addShutdownHook, any, asType, bitwiseNegate, center, charAt, codePointAt, codePointBefore, codePointCount, collect, compareTo, compareToIgnoreCase, concat, contains, contentEquals, copyValueOf, count, decodeBase64, denormalize, dump, each, eachLine, eachMatch, eachWithIndex, endsWith, equals, equalsIgnoreCase, every, execute, find, findAll, findIndexOf, findIndexValues, findLastIndexOf, format, getAt, getBytes, getChars, getClass, getMetaClass, getMetaPropertyValues, getProperties, grep, hasProperty, hashCode, identity, indexOf, inject, inspect, intern, invokeMethod, is, isBigDecimal, isBigInteger, isCase, isDouble, isEmpty, isFloat, isInteger, isLong, isNumber, iterator, lastIndexOf, leftShift, length, matches, metaClass, minus, multiply, next, normalize, notify, notifyAll, numberAwareCompareTo, offsetByCodePoints, padLeft, padRight, plus, previous, print, printf, println, putAt, readLines, regionMatches, replace, replaceAll, replaceFirst, respondsTo, reverse, setMetaClass, size, sleep, split, splitEachLine, sprintf, startsWith, subSequence, substring, toBigDecimal, toBigInteger, toBoolean, toCharArray, toCharacter, toDouble, toFloat, toInteger, toList, toLong, toLowerCase, toShort, toString, toURI, toURL, toUpperCase, tokenize, trim, use, valueOf, wait, with]

As I said, most of the time just looking at the “methods” gives me what I want, but this is the way to get the exhaustive list.

Does not work. Some methods are missing. For example, if I have a variable referencing a string, I have more methods listed with inspect’ than using the expression you are suggesting. ‘each’ is listed with ‘inspect’ and not listed using your method.

Nice! This should do until the groovy / Eclipse plugin is auto-completing properly

Thanks for the article, it was a real help when I was looking for an equivalent of Ruby’s “methods”.

This seems a lot nicer than groovy.inspect.Inspector, which is what I’ve been fighting with recently.
