- if an I/O error has occurredpublic Certificate[] getCertificates()
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).
Certificate
objects for this entry, or null
if none.public CodeSigner[] getCodeSigners()
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.
CodeSigner
objects for this entry, or null
if none.public String getRealName()
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.
