Method Detail

values

public static Releasables[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Releasables c : Releasables.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Releasables valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

close

public static void close(java.lang.Iterable<? extends Releasable> releasables)

Release the provided Releasables.

close

public static void close(Releasable... releasables)

Release the provided Releasables.

closeWhileHandlingException

public static void closeWhileHandlingException(java.lang.Iterable<Releasable> releasables)

Release the provided Releasables, ignoring exceptions.

closeWhileHandlingException

public static void closeWhileHandlingException(Releasable... releasables)

Release the provided Releasables, ignoring exceptions.

close

public static void close(boolean success,
                         java.lang.Iterable<Releasable> releasables)

Release the provided Releasables, ignoring exceptions if success is false.

close

public static void close(boolean success,
                         Releasable... releasables)

Release the provided Releasables, ignoring exceptions if success is false.

wrap

public static Releasable wrap(java.lang.Iterable<Releasable> releasables)

Wrap several releasables into a single one. This is typically useful for use with try-with-resources: for example let's assume that you store in a list several resources that you would like to see released after execution of the try block:

  List<Releasable> resources = ...;
  try (Releasable releasable = Releasables.wrap(resources)) {
      // do something
  }
  // the resources will be released when reaching here
  

wrap

public static Releasable wrap(Releasable... releasables)

wrap(Iterable)

releaseOnce

public static Releasable releaseOnce(Releasable... releasables)

Equivalent to wrap(Releasable...) but can be called multiple times without double releasing.
