Method Detail

• type

  public static java.lang.Class<?> type(java.lang.Object x)

  returns the Class of anything which isn't a class; if input is class it is pass-through

• componentType

  public static java.lang.Class<?> componentType(java.lang.Object x)

  like type, but removes any array modifiers

• simpleClassName

  public static java.lang.String simpleClassName(java.lang.Class<?> t)

  returns a simplified name of the class, just the simple name if it seems useful, else the full name

• simpleClassName

  public static java.lang.String simpleClassName(java.lang.Object x)

  as simpleClassName(Class) but taking the type of the object if it is not already a class or a type-token; callers should usually do the getClass themselves, unless they aren't sure whether it is already a Class-type object

• simplifyClassName

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

  as simpleClassName(Class) but taking a string rep'n of the class name, and doing best effort to simplify it (without instantiating)

• cleanSimpleClassName

  public static java.lang.String cleanSimpleClassName(java.lang.Object x)

  as simpleClassName(Object) but making the result clean for use on filesystems and as java identifiers

• cleanSimpleClassName

  public static java.lang.String cleanSimpleClassName(java.lang.Class<?> x)

  as simpleClassName(Object) but making the result clean for use on filesystems and as java identifiers

• packageName

  public static java.lang.String packageName(java.lang.Object x)

• packagePath

  public static java.lang.String packagePath(java.lang.Object x)

  returns e.g. "/com/acme/" for an object in package com.acme

• resolveName

  public static java.lang.String resolveName(java.lang.Object context,
                             java.lang.String path)

  returns path relative to the package of x, unless path is absolute. useful to mimic Class.getResource(path) behaviour, cf Class.resolveName where the first argument below is the class.

• resolveClasspathUrl

  public static java.lang.String resolveClasspathUrl(java.lang.Object context,
                                     java.lang.String path)

  returns a "classpath:" URL given a context object and a file to be found in that directory or a sub-directory (ignoring the context object if the given path is absolute, i.e. starting with "/" or "protocol:") e.g. "classpath://com/acme/foo.txt" given a context object com.acme.SomeClass and "foo.txt"

• currentStackTraceCleaned

  public static java.lang.StackTraceElement[] currentStackTraceCleaned()

  returns a cleaned stack trace; caller is usually at the top

• currentStackElement

  public static java.lang.StackTraceElement currentStackElement()

  returns top of cleaned stack trace; usually the caller's location

• callerStackElement

  public static java.lang.StackTraceElement callerStackElement(int depth)

  returns element in cleaned stack trace; usually the caller's location is at the top, and caller of that is up one, etc

• niceClassAndMethod

  public static java.lang.String niceClassAndMethod(java.lang.StackTraceElement st)

  returns nice class name and method for the given element

• callerNiceClassAndMethod

  public static java.lang.String callerNiceClassAndMethod(int depth)

  returns nice class name and method for the caller, going up the stack (filtered to remove invocation etc), with 0 typically being the context where this method is called, 1 being its caller, etc

• niceClassAndMethod

  public static java.lang.String niceClassAndMethod()

  convenience for callerNiceClassAndMethod(int) with depth 0

  useful for tests and other debug-facing log messages!
