Inherited functions

From class ZipEntry

`Any`	`clone()` Returns a copy of this entry.
`String!`	`getComment()` Returns the comment string for the entry.
`Long`	`getCompressedSize()` Returns the size of the compressed entry data. In the case of a stored entry, the compressed size will be the same as the uncompressed size of the entry.
`Long`	`getCrc()` Returns the CRC-32 checksum of the uncompressed entry data.
`FileTime!`	`getCreationTime()` Returns the creation time of the entry. The creation time is from the extended timestamp fields of entry's `optional extra data` when read from a ZIP file or ZIP file formatted stream.
`ByteArray!`	`getExtra()` Returns the extra field data for the entry.
`FileTime!`	`getLastAccessTime()` Returns the last access time of the entry. The last access time is from the extended timestamp fields of entry's `optional extra data` when read from a ZIP file or ZIP file formatted stream.
`FileTime!`	`getLastModifiedTime()` Returns the last modification time of the entry. If the entry is read from a ZIP file or ZIP file formatted input stream, this is the last modification time from the zip file entry's `optional extra data` if the extended timestamp fields are present. Otherwise the last modification time is read from the entry's `date and time fields`, the `default TimeZone` is used to convert the standard MS-DOS formatted date and time to the epoch time.
`Int`	`getMethod()` Returns the compression method of the entry.
`String!`	`getName()` Returns the name of the entry.
`Long`	`getSize()` Returns the uncompressed size of the entry data.
`Long`	`getTime()` Returns the last modification time of the entry. If the entry is read from a ZIP file or ZIP file formatted input stream, this is the last modification time from the `date and time fields` of the zip file entry. The `default TimeZone` is used to convert the standard MS-DOS formatted date and time to the epoch time.
`LocalDateTime!`	`getTimeLocal()` Returns the last modification time of the entry in local date-time. If the entry is read from a ZIP file or ZIP file formatted input stream, this is the last modification time from the zip file entry's `optional extra data` if the extended timestamp fields are present. Otherwise, the last modification time is read from entry's standard MS-DOS formatted `date and time fields`. The `system default TimeZone` is used to convert the UTC time to local date-time.
`Int`	`hashCode()` Returns the hash code value for this entry.
`Boolean`	`isDirectory()` Returns true if this is a directory entry. A directory entry is defined to be one whose name ends with a '/'.
`Unit`	`setComment(comment: String!)` Sets the optional comment string for the entry. ZIP entry comments have maximum length of 0xffff. If the length of the specified comment string is greater than 0xFFFF bytes after encoding, only the first 0xFFFF bytes are output to the ZIP file entry.
`Unit`	`setCompressedSize(csize: Long)` Sets the size of the compressed entry data.
`Unit`	`setCrc(crc: Long)` Sets the CRC-32 checksum of the uncompressed entry data.
`ZipEntry!`	`setCreationTime(time: FileTime!)` Sets the creation time of the entry. If set, the creation time will be stored into the extended timestamp fields of entry's `optional extra data`, when output to a ZIP file or ZIP file formatted stream.
`Unit`	`setExtra(extra: ByteArray!)` Sets the optional extra field data for the entry. Invoking this method may change this entry's last modification time, last access time and creation time, if the `extra` field data includes the extensible timestamp fields, such as `NTFS tag 0x0001` or `Info-ZIP Extended Timestamp`, as specified in Info-ZIP Application Note 970311.
`ZipEntry!`	`setLastAccessTime(time: FileTime!)` Sets the last access time of the entry. If set, the last access time will be stored into the extended timestamp fields of entry's `optional extra data`, when output to a ZIP file or ZIP file formatted stream.
`ZipEntry!`	`setLastModifiedTime(time: FileTime!)` Sets the last modification time of the entry. When output to a ZIP file or ZIP file formatted output stream the last modification time set by this method will be stored into zip file entry's `date and time fields` in `standard MS-DOS date and time format`), and the extended timestamp fields in `optional extra data` in UTC time.
`Unit`	`setMethod(method: Int)` Sets the compression method for the entry.
`Unit`	`setSize(size: Long)` Sets the uncompressed size of the entry data.
`Unit`	`setTime(time: Long)` Sets the last modification time of the entry. If the entry is output to a ZIP file or ZIP file formatted output stream the last modification time set by this method will be stored into the `date and time fields` of the zip file entry and encoded in standard `MS-DOS date and time format`. The `default TimeZone` is used to convert the epoch time to the MS-DOS data and time.
`Unit`	`setTimeLocal(time: LocalDateTime!)` Sets the last modification time of the entry in local date-time. If the entry is output to a ZIP file or ZIP file formatted output stream the last modification time set by this method will be stored into the `date and time fields` of the zip file entry and encoded in standard `MS-DOS date and time format`. If the date-time set is out of the range of the standard `MS-DOS date and time format`, the time will also be stored into zip file entry's extended timestamp fields in `optional extra data` in UTC time. The `system default TimeZone` is used to convert the local date-time to UTC time. `LocalDateTime` uses a precision of nanoseconds, whereas this class uses a precision of milliseconds. The conversion will truncate any excess precision information as though the amount in nanoseconds was subject to integer division by one million.
`String`	`toString()` Returns a string representation of the ZIP entry.
