jdk.nio.file.StandardOpenOption
*value-ofclj
(*value-of 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.)
name - the name of the enum constant to be returned. - java.lang.String
returns: the enum constant with the specified name - java.nio.file.StandardOpenOption
throws: java.lang.IllegalArgumentException - if this enum type has no constant with the specified 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.) name - the name of the enum constant to be returned. - `java.lang.String` returns: the enum constant with the specified name - `java.nio.file.StandardOpenOption` throws: java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
*valuesclj
(*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 (StandardOpenOption c : StandardOpenOption.values()) System.out.println(c);
returns: an array containing the constants of this enum type, in the order they are declared - java.nio.file.StandardOpenOption[]
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 (StandardOpenOption c : StandardOpenOption.values())
System.out.println(c);
returns: an array containing the constants of this enum type, in the order they are declared - `java.nio.file.StandardOpenOption[]`APPENDclj
Enum Constant.
If the file is opened for WRITE access then bytes will be written to the end of the file rather than the beginning.
If the file is opened for write access by other programs, then it is file system specific if writing to the end of the file is atomic.
type: java.nio.file.StandardOpenOption
Enum Constant. If the file is opened for WRITE access then bytes will be written to the end of the file rather than the beginning. If the file is opened for write access by other programs, then it is file system specific if writing to the end of the file is atomic. type: java.nio.file.StandardOpenOption
CREATEclj
Enum Constant.
Create a new file if it does not exist. This option is ignored if the CREATE_NEW option is also set. The check for the existence of the file and the creation of the file if it does not exist is atomic with respect to other file system operations.
type: java.nio.file.StandardOpenOption
Enum Constant. Create a new file if it does not exist. This option is ignored if the CREATE_NEW option is also set. The check for the existence of the file and the creation of the file if it does not exist is atomic with respect to other file system operations. type: java.nio.file.StandardOpenOption
CREATE_NEWclj
Enum Constant.
Create a new file, failing if the file already exists. The check for the existence of the file and the creation of the file if it does not exist is atomic with respect to other file system operations.
type: java.nio.file.StandardOpenOption
Enum Constant. Create a new file, failing if the file already exists. The check for the existence of the file and the creation of the file if it does not exist is atomic with respect to other file system operations. type: java.nio.file.StandardOpenOption
DELETE_ON_CLOSEclj
Enum Constant.
Delete on close. When this option is present then the implementation makes a best effort attempt to delete the file when closed by the appropriate close method. If the close method is not invoked then a best effort attempt is made to delete the file when the Java virtual machine terminates (either normally, as defined by the Java Language Specification, or where possible, abnormally). This option is primarily intended for use with work files that are used solely by a single instance of the Java virtual machine. This option is not recommended for use when opening files that are open concurrently by other entities. Many of the details as to when and how the file is deleted are implementation specific and therefore not specified. In particular, an implementation may be unable to guarantee that it deletes the expected file when replaced by an attacker while the file is open. Consequently, security sensitive applications should take care when using this option.
For security reasons, this option may imply the LinkOption.NOFOLLOW_LINKS option. In other words, if the option is present when opening an existing file that is a symbolic link then it may fail (by throwing IOException).

DSYNCclj
Enum Constant.
Requires that every update to the file's content be written synchronously to the underlying storage device.
type: java.nio.file.StandardOpenOption
Enum Constant. Requires that every update to the file's content be written synchronously to the underlying storage device. type: java.nio.file.StandardOpenOption
READclj
Enum Constant.
Open for read access.
type: java.nio.file.StandardOpenOption
Enum Constant. Open for read access. type: java.nio.file.StandardOpenOption
SPARSEclj
Enum Constant.
Sparse file. When used with the CREATE_NEW option then this option provides a hint that the new file will be sparse. The option is ignored when the file system does not support the creation of sparse files.
type: java.nio.file.StandardOpenOption
Enum Constant. Sparse file. When used with the CREATE_NEW option then this option provides a hint that the new file will be sparse. The option is ignored when the file system does not support the creation of sparse files. type: java.nio.file.StandardOpenOption

TRUNCATE_EXISTINGclj
Enum Constant.
If the file already exists and it is opened for WRITE access, then its length is truncated to 0. This option is ignored if the file is opened only for READ access.
