Constructor Detail
JarEntry
public JarEntry(String name)
Creates a new JarEntry
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
public JarEntry(ZipEntry ze)
Creates a new JarEntry
with fields taken from the specified ZipEntry
object.
- Parameters:
-
ze
- theZipEntry
object to create theJarEntry
from
JarEntry
public JarEntry(JarEntry je)
Creates a new JarEntry
with fields taken from the specified JarEntry
object.
- Parameters:
-
je
- theJarEntry
to copy
Method Detail
getAttributes
public Attributes getAttributes() throws IOException
Returns the Manifest
Attributes
for this entry, or null
if none.
- Returns:
- the
Manifest
Attributes
for this entry, ornull
if none - Throws:
-
IOException
- if an I/O error has occurred
getCertificates
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:
- the
Certificate
objects for this entry, ornull
if none.
getCodeSigners
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:
- the
CodeSigner
objects for this entry, ornull
if none. - Since:
- 1.5
getRealName
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:
- the real name of the JarEntry
- Since:
- 10
