Enum IoUtil.CollisionStrategy

java.lang.Object

java.lang.Enum<IoUtil.CollisionStrategy>

de.unkrig.commons.io.IoUtil.CollisionStrategy

All Implemented Interfaces:

Serializable, Comparable<IoUtil.CollisionStrategy>

Enclosing class:

IoUtil

public static enum IoUtil.CollisionStrategy
extends Enum<IoUtil.CollisionStrategy>

Determines the behavior of the IoUtil.copyTree(File, File, CollisionStrategy) and IoUtil.copyTree(File, File, CollisionStrategy) methods when files collide while copying.

Enum Constant Summary

Enum Constants

Enum Constant and Description
IO_EXCEPTION Throw an IOException indicating the fact.
IO_EXCEPTION_IF_DIFFERENT If the content of the input file and the output file is identical, do nothing.
LEAVE_OLD Do nothing; the input file is not copied, and the output file remains unchanged.
OVERWRITE Re-create the output file and copy the contents of the input file into it.

Method Summary

Modifier and Type	Method and Description
static IoUtil.CollisionStrategy	valueOf(String name) Returns the enum constant of this type with the specified name.
static IoUtil.CollisionStrategy[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

LEAVE_OLD

public static final IoUtil.CollisionStrategy LEAVE_OLD

Do nothing; the input file is not copied, and the output file remains unchanged.

OVERWRITE

public static final IoUtil.CollisionStrategy OVERWRITE

Re-create the output file and copy the contents of the input file into it. The original content of the output file is lost.

IO_EXCEPTION

public static final IoUtil.CollisionStrategy IO_EXCEPTION

Throw an IOException indicating the fact.

IO_EXCEPTION_IF_DIFFERENT

public static final IoUtil.CollisionStrategy IO_EXCEPTION_IF_DIFFERENT

If the content of the input file and the output file is identical, do nothing. Otherwise throw an IOException indicating the fact.

Method Detail

values

public static IoUtil.CollisionStrategy[] 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 (IoUtil.CollisionStrategy c : IoUtil.CollisionStrategy.values())
    System.out.println(c);

Returns:

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

valueOf

public static IoUtil.CollisionStrategy valueOf(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:

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

NullPointerException - if the argument is null
