Enum Constant Summary

Enum Constants

Enum Constant and Description
DIFF_DATA Indicates this address has been already written and it is a different data (derived from the length).
HOLE Indicates this address has been already written by a hole.
NONE Indicates there is no actual cause for the overwrite, hence no overwrite exception has occurred.
SAME_DATA Indicates this address has been already written and it is 'potentially' the same data (i.e., based on data length).
TRIM Indicates this address was already trimmed.

Method Summary

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

Enum Constant Detail

HOLE

public static final OverwriteCause HOLE

Indicates this address has been already written by a hole.

SAME_DATA

public static final OverwriteCause SAME_DATA

Indicates this address has been already written and it is 'potentially' the same data (i.e., based on data length). The client will drive final verification. This intends to be a hint so verification is only driven in very specific cases.

DIFF_DATA

public static final OverwriteCause DIFF_DATA

Indicates this address has been already written and it is a different data (derived from the length).

TRIM

public static final OverwriteCause TRIM

Indicates this address was already trimmed.

NONE

public static final OverwriteCause NONE

Indicates there is no actual cause for the overwrite, hence no overwrite exception has occurred.

Method Detail

values

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

Returns:

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

valueOf

public static OverwriteCause 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

fromId

public static OverwriteCause fromId(int id)
