Constructor Details
-
JarEntry
Creates a newJarEntry
for the specified JAR file entry name.- Parameters:
name
- the JAR file entry name- Throws:
NullPointerException
- if the entry name isnull
IllegalArgumentException
- if the entry name is longer than 0xFFFF bytes.
-
JarEntry
Creates a newJarEntry
with fields taken from the specifiedZipEntry
object.- Parameters:
ze
- theZipEntry
object to create theJarEntry
from
-
JarEntry
Creates a newJarEntry
with fields taken from the specifiedJarEntry
object.- Parameters:
je
- theJarEntry
to copy
-
-
Method Details
-
getAttributes
Returns theManifest
Attributes
for this entry, ornull
if none.- Returns:
- the
Manifest
Attributes
for this entry, ornull
if none - Throws:
IOException
- if an I/O error has occurred
-
getCertificates
Returns theCertificate
objects for this entry, ornull
if none. This method can only be called once theJarEntry
has been completely verified by reading from the entry input stream until the end of the stream has been reached. Otherwise, this method will returnnull
.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:
- the
Certificate
objects for this entry, ornull
if none.
-
getCodeSigners
Returns theCodeSigner
objects for this entry, ornull
if none. This method can only be called once theJarEntry
has been completely verified by reading from the entry input stream until the end of the stream has been reached. Otherwise, this method will returnnull
.The returned array comprises all the code signers that have signed this entry.
- Returns:
- the
CodeSigner
objects for this entry, ornull
if none. - Since:
- 1.5
-
getRealName
Returns the real name of thisJarEntry
. If thisJarEntry
is an entry of a multi-release jar file and theJarFile
is configured to be processed as such, the name returned by this method is the path name of the versioned entry that theJarEntry
represents, rather than the path name of the base entry thatZipEntry.getName()
returns. If theJarEntry
does not represent a versioned entry of a multi-releaseJarFile
or theJarFile
is not configured for processing a multi-release jar file, this method returns the same name thatZipEntry.getName()
returns.- Returns:
- the real name of the JarEntry
- Since:
- 10
