public abstract class Attribute

extends java.lang.Object

An attribute is a key used to refer to some property of a document.

Attribute class is an abstract parent class for different types of attributes. An concrete attribute has a name and a type. The type refers to the type of the attribute values it can be associated with.

Currently the following types are supported: String, Number, Date. Each are implemented in subclasses StringAttribute, NumberAttribute, DateAttribute.

Note: attribute names should be treated case-insensitively. So string attributes named "Author" and "AUTHOR" refer to the same attribute. Nevertheless, Attribute class leaves capitalization of the name unchanged, so getName() always returns the name used in the construction of the object.

Method Detail

getId

public int getId()

Get the attribute's id

getUniqueName

public abstract java.lang.String getUniqueName()

Get the attribute's unique name. An unique attribute name is synthesized by concatenating the attribute name with the attribute type, using an underscore.
For example: a StringAttribute named "A" is uniquely identified by "A_STRING". Likewise for NumberAttribute and DateAttribute: "A_NUMBER", "A_DATE".

Returns:

attribute's unique name

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this one. Two attribute objects are equal if and only if

• they are of the same type (class), and
• they have the same ID.

Overrides:

equals in class java.lang.Object

Returns:

true if this attribute is same as the obj argument, false otherwise
