Manifest
public Manifest()
Creates a new empty Manifest.
Manifest
public Manifest(InputStream in)
throws IOException Creates a Manifest from the supplied input stream.
in - the input stream to read the manifest from
IOException - when an i/o exception occurs or the input stream
does not describe a valid manifest
Manifest
public Manifest(Manifest man)
Creates a Manifest from another Manifest.
Makes a deep copy of the main attributes, but a shallow copy of
the other entries. This means that you can freely add, change or remove
the main attributes or the entries of the new manifest without effecting
the original manifest, but adding, changing or removing attributes from
a particular entry also changes the attributes of that entry in the
original manifest.
man - the Manifest to copy from
Attributes> getEntries
public MapAttributes> getEntries()
Gets a map of entry Strings to Attributes for all the entries described
in this manifest. Adding, changing or removing from this entries map
changes the entries of this manifest.
clear
public void clear()
Clears the main attributes and removes all the entries from the
manifest.
clone
public Object clone()
Makes a deep copy of the main attributes, but a shallow copy of
the other entries. This means that you can freely add, change or remove
the main attributes or the entries of the new manifest without effecting
the original manifest, but adding, changing or removing attributes from
a particular entry also changes the attributes of that entry in the
original manifest. Calls new Manifest(this).
- clone in interface Object
equals
public boolean equals(Object o)
Checks if another object is equal to this Manifest object.
Another Object is equal to this Manifest object if it is an instance of
Manifest and the main attributes and the entries of the other manifest
are equal to this one.
- equals in interface Object
getAttributes
public Attributes getAttributes(String entryName)
Returns the Attributes associated with the Entry.
Implemented as:
return (Attributes)getEntries().get(entryName)
entryName - the name of the entry to look up
- the attributes associated with the entry or null when none
hashCode
public int hashCode()
Calculates the hash code of the manifest. Implemented by a xor of the
hash code of the main attributes with the hash code of the entries map.
- hashCode in interface Object
read
public void read(InputStream in)
throws IOException Read and merge a Manifest from the designated input stream.
in - the input stream to read from.
IOException - if an I/O related exception occurs during the process.
write
public void write(OutputStream out)
throws IOException Writes the contents of this Manifest to the designated
output stream. Line-endings are platform-independent and consist of the
2-codepoint sequence 0x0D and 0x0A.
out - the output stream to write this Manifest to.
IOException - if an I/O related exception occurs during the process.
