Manifest
open class Manifest : Cloneable
| kotlin.Any | |
| ↳ | java.util.jar.Manifest |
The Manifest class is used to maintain Manifest entry names and their associated Attributes. There are main Manifest Attributes as well as per-entry Attributes. For information on the Manifest format, please see the Manifest format specification.

Public constructors
Manifest
Manifest(is: InputStream!)
Constructs a new Manifest from the specified input stream.
| Parameters | |
|---|---|
is |
InputStream!: the input stream containing manifest data |
| Exceptions | |
|---|---|
java.io.IOException |
if an I/O error has occurred |
Manifest
Manifest(man: Manifest!)
Constructs a new Manifest that is a copy of the specified Manifest.
| Parameters | |
|---|---|
man |
Manifest!: the Manifest to copy |
Public methods
clear
open fun clear(): Unit
Clears the main Attributes as well as the entries in this Manifest.
clone
open fun clone(): Any
Returns a shallow copy of this Manifest. The shallow copy is implemented as follows:
public Object clone() { return new Manifest(this); }
| Return | |
|---|---|
Any |
a shallow copy of this Manifest |
| Exceptions | |
|---|---|
java.lang.CloneNotSupportedException |
if the object's class does not support the Cloneable interface. Subclasses that override the clone method can also throw this exception to indicate that an instance cannot be cloned. |
equals
open fun equals(other: Any?): Boolean
Returns true if the specified Object is also a Manifest and has the same main Attributes and entries.
| Parameters | |
|---|---|
obj |
the reference object with which to compare. |
o |
the object to be compared |
| Return | |
|---|---|
Boolean |
true if the specified Object is also a Manifest and has the same main Attributes and entries |
getAttributes
open fun getAttributes(name: String!): Attributes!
Returns the Attributes for the specified entry name. This method is defined as:
return (Attributes)getEntries().get(name)
null is a valid name, when getAttributes(null) is invoked on a Manifest obtained from a jar file, null will be returned. While jar files themselves do not allow null-named attributes, it is possible to invoke getEntries on a Manifest, and on that result, invoke put with a null key and an arbitrary value. Subsequent invocations of getAttributes(null) will return the just-put value.
Note that this method does not return the manifest's main attributes; see getMainAttributes.
| Parameters | |
|---|---|
name |
String!: entry name |
| Return | |
|---|---|
Attributes! |
the Attributes for the specified entry name |
getEntries
open fun getEntries(): MutableMap<String!, Attributes!>!
Returns a Map of the entries contained in this Manifest. Each entry is represented by a String name (key) and associated Attributes (value). The Map permits the null key, but no entry with a null key is created by read, nor is such an entry written by using write.
| Return | |
|---|---|
MutableMap<String!, Attributes!>! |
a Map of the entries contained in this Manifest |
getMainAttributes
open fun getMainAttributes(): Attributes!
Returns the main Attributes for the Manifest.
| Return | |
|---|---|
Attributes! |
the main Attributes for the Manifest |
hashCode
open fun hashCode(): Int
Returns the hash code for this Manifest.
| Return | |
|---|---|
Int |
a hash code value for this object. |
read
open fun read(is: InputStream!): Unit
Reads the Manifest from the specified InputStream. The entry names and attributes read will be merged in with the current manifest entries.
| Parameters | |
|---|---|
is |
InputStream!: the input stream |
| Exceptions | |
|---|---|
java.io.IOException |
if an I/O error has occurred |
write
open fun write(out: OutputStream!): Unit
Writes the Manifest to the specified OutputStream. Attributes.Name.MANIFEST_VERSION must be set in MainAttributes prior to invoking this method.
| Parameters | |
|---|---|
out |
OutputStream!: the output stream |
| Exceptions | |
|---|---|
java.io.IOException |
if an I/O error has occurred |
