Method Detail

hashCode

public int hashCode()

Description copied from class: Object

Suppressed: Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the java.lang.Object#equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java^TM programming language.)

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

java.lang.Object#equals(java.lang.Object), java.util.Hashtable

equals

public boolean equals(Object thatObject)

Two parameter lists are considered equal if they have exactly the same set of parameter names and associated values. The order of the parameters is not considered.

Overrides:

equals in class Object

Parameters:

thatObject - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

Object.hashCode(), java.util.Hashtable

parse

protected void parse(String rawdata)
              throws MimeTypeParseException

A routine for parsing the parameter list out of a String.

MimeTypeParseException

size

public int size()

return the number of name-value pairs in this list.

isEmpty

public boolean isEmpty()

Determine whether or not this list is empty.

get

public String get(String name)

Retrieve the value associated with the given name, or null if there is no current association.

set

public void set(String name,
                String value)

Set the value to be associated with the given name, replacing any previous association.

remove

public void remove(String name)

Remove any value associated with the given name.

getNames

public Enumeration getNames()

Retrieve an enumeration of all the names in this list.

toString

public String toString()

Description copied from class: Object

Suppressed: Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:

toString in class Object

Returns:

a string representation of the object.

clone

public Object clone()

Description copied from class: Object

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:

 x.clone() != x

will be true, and that the expression:

 x.clone().getClass() == x.getClass()

will be true, but these are not absolute requirements. While it is typically the case that:

 x.clone().equals(x)

will be true, this is not an absolute requirement.

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

The method clone for class Object performs a specific cloning operation. First, if the class of this object does not implement the interface Cloneable, then a CloneNotSupportedException is thrown. Note that all arrays are considered to implement the interface Cloneable. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.

The class Object does not itself implement the interface Cloneable, so calling the clone method on an object whose class is Object will result in throwing an exception at run time.

Overrides:

clone in class Object

Returns:

a clone of this object

isTokenChar

private static boolean isTokenChar(char c)

Determine whether or not a given character belongs to a legal token.

skipWhiteSpace

private static int skipWhiteSpace(String rawdata,
                                  int i)

return the index of the first non white space character in rawdata at or after index i.

quote

private static String quote(String value)

A routine that knows how and when to quote and escape the given value.

unquote

private static String unquote(String value)

A routine that knows how to strip the quotes and escape sequences from the given value.
