Attribute

public Attribute()

Construct an empty attribute

Attribute

public Attribute(String line)
          throws ManifestException

Construct an attribute by parsing a line from the Manifest

Parameters:

line - the line containing the attribute name and value

Throws:

ManifestException - if the line is not valid

Attribute

public Attribute(String name,
 String value)

Construct a manifest by specifying its name and value

Parameters:

name - the attribute's name

value - the Attribute's value

Method Details

hashCode

public int hashCode()

Overrides:

hashCode in class Object

Returns:

a hashcode based on the key and values.

See Also:

• Object.hashCode()

equals

public boolean equals(Object rhs)

Overrides:

equals in class Object

Parameters:

rhs - the object to check for equality.

Returns:

true if the key and values are the same.

See Also:

• Object.equals(java.lang.Object)

parse

public void parse(String line)
           throws ManifestException

Parse a line into name and value pairs

Parameters:

line - the line to be parsed

Throws:

ManifestException - if the line does not contain a colon separating the name and value

setName

public void setName(String name)

Set the Attribute's name; required

Parameters:

name - the attribute's name

getName

public String getName()

Get the Attribute's name

Returns:

the attribute's name.

getKey

public String getKey()

Get the attribute's Key - its name in lower case.

Returns:

the attribute's key.

setValue

public void setValue(String value)

Set the Attribute's value; required

Parameters:

value - the attribute's value

getValue

public String getValue()

Get the Attribute's value.

Returns:

the attribute's value.

addValue

public void addValue(String value)

Add a new value to this attribute - making it multivalued.

Parameters:

value - the attribute's additional value

getValues

public Enumeration<String> getValues()

Get all the attribute's values.

Returns:

an enumeration of the attributes values

addContinuation

public void addContinuation(String line)

Add a continuation line from the Manifest file. When lines are too long in a manifest, they are continued on the next line by starting with a space. This method adds the continuation data to the attribute value by skipping the first character.

Parameters:

line - the continuation line.

write

public void write(PrintWriter writer)
           throws IOException

Write the attribute out to a print writer without flattening multi-values attributes (i.e. Class-Path).

Parameters:

writer - the Writer to which the attribute is written

Throws:

IOException - if the attribute value cannot be written

write

public void write(PrintWriter writer,
 boolean flatten)
           throws IOException

Write the attribute out to a print writer.

Parameters:

writer - the Writer to which the attribute is written

flatten - whether to collapse multi-valued attributes (i.e. potentially Class-Path) Class-Path into a single attribute.

Throws:

IOException - if the attribute value cannot be written
