Public constructors

JarEntry

Added in API level 1

public JarEntry (String name)

Creates a new JarEntry for the specified JAR file entry name.

Parameters
`name`	`String`: the JAR file entry name

Throws
`NullPointerException`	if the entry name is `null`
`IllegalArgumentException`	if the entry name is longer than 0xFFFF bytes.

JarEntry

Added in API level 1

public JarEntry (ZipEntry ze)

Creates a new JarEntry with fields taken from the specified ZipEntry object.

Parameters
`ze`	`ZipEntry`: the `ZipEntry` object to create the `JarEntry` from

JarEntry

Added in API level 1

public JarEntry (JarEntry je)

Creates a new JarEntry with fields taken from the specified JarEntry object.

Parameters
`je`	`JarEntry`: the `JarEntry` to copy

Public methods

getAttributes

Added in API level 1

public Attributes getAttributes ()

Returns the Manifest Attributes for this entry, or null if none.

Returns
`Attributes`	the `Manifest` `Attributes` for this entry, or `null` if none

Throws
`IOException`	if an I/O error has occurred

getCertificates

Added in API level 1

public Certificate[] getCertificates ()

Returns the Certificate objects for this entry, or null if none. This method can only be called once the JarEntry has been completely verified by reading from the entry input stream until the end of the stream has been reached. Otherwise, this method will return null.

The returned certificate array comprises all the signer certificates that were used to verify this entry. Each signer certificate is followed by its supporting certificate chain (which may be empty). Each signer certificate and its supporting certificate chain are ordered bottom-to-top (i.e., with the signer certificate first and the (root) certificate authority last).

Returns
`Certificate[]`	the `Certificate` objects for this entry, or `null` if none.

getCodeSigners

Added in API level 1

public CodeSigner[] getCodeSigners ()

Returns the CodeSigner objects for this entry, or null if none. This method can only be called once the JarEntry has been completely verified by reading from the entry input stream until the end of the stream has been reached. Otherwise, this method will return null.

The returned array comprises all the code signers that have signed this entry.

Returns
`CodeSigner[]`	the `CodeSigner` objects for this entry, or `null` if none.

getRealName

Added in API level 33

public String getRealName ()

Returns the real name of this JarEntry. If this JarEntry is an entry of a multi-release jar file and the JarFile is configured to be processed as such, the name returned by this method is the path name of the versioned entry that the JarEntry represents, rather than the path name of the base entry that ZipEntry.getName() returns. If the JarEntry does not represent a versioned entry of a multi-release JarFile or the JarFile is not configured for processing a multi-release jar file, this method returns the same name that ZipEntry.getName() returns.

Returns
`String`	the real name of the JarEntry
