public static final EFileIOErrorCode SOURCE_EQUALS_TARGET

Source and destination object are identical.

TARGET_IS_CHILD_OF_SOURCE

public static final EFileIOErrorCode TARGET_IS_CHILD_OF_SOURCE

Avoid recursive dependencies.

OBJECT_CANNOT_BE_HANDLED

public static final EFileIOErrorCode OBJECT_CANNOT_BE_HANDLED

We stumble across an object that is neither a file nor a directory.

OBJECT_HAS_NO_PARENT

public static final EFileIOErrorCode OBJECT_HAS_NO_PARENT

An object's parent could not be retrieved.

SOURCE_NOT_READABLE

public static final EFileIOErrorCode SOURCE_NOT_READABLE

The source object cannot be read.

SOURCE_PARENT_NOT_WRITABLE

public static final EFileIOErrorCode SOURCE_PARENT_NOT_WRITABLE

The source parent object is read-only (not writable).

TARGET_PARENT_NOT_WRITABLE

public static final EFileIOErrorCode TARGET_PARENT_NOT_WRITABLE

The target parent object is read-only (not writable).

Method Detail

values

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

Returns:

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

valueOf

public static EFileIOErrorCode 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

getID

@Nonnegative
public int getID()

An internal ID for easier referencing. NO_ERROR has ID 0. All errors have positive numbers.

Specified by:

getID in interface IHasIntID

Returns:

The primitive int ID of this object.

getAsIOError

@Nonnull
public FileIOError getAsIOError(@Nonnull
                               EFileIOOperation eOperation,
                               @Nonnull
                               File aFile)

Use this error code to create a new FileIOError instance.

Parameters:

eOperation - The operation carried out. May not be null.

aFile - The file on which operation was carried out. May not be null.

Returns:

The new FileIOError and never null.

getAsIOError

@Nonnull
public FileIOError getAsIOError(@Nonnull
                               EFileIOOperation eOperation,
                               @Nonnull
                               File aFile1,
                               @Nonnull
                               File aFile2)

Use this error code to create a new FileIOError instance.

Parameters:

eOperation - The operation carried out. May not be null.

aFile1 - The first file on which operation was carried out. May not be null.

aFile2 - The second file on which operation was carried out. May not be null.
