public AttributeDefinition(int code,
                           java.lang.String label)

Method Detail

getLabel

public java.lang.String getLabel()

getCode

public int getCode()

hashCode

public int hashCode()

Overrides Object hashCode method. Note that the hash code is computed purely from the ID, so two distinct instances that have the same identifier (i.e., full name) will have the same hash code value.

This hash code must be consistent with the equals method. defined by subclasses.

Overrides:

hashCode in class java.lang.Object

Returns:

the hash code value for this metadata object.

equals

public boolean equals(java.lang.Object obj)

Returns true if the specified object is semantically equal to this instance. Note: this method is consistent with compareTo().

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object that this instance is to be compared to.

Returns:

whether the object is equal to this object.

compareTo

public int compareTo(java.lang.Object obj)

Compares this object to another. If the specified object is an instance of the same class, then this method compares the name; otherwise, it throws a ClassCastException (as instances are comparable only to instances of the same class). Note: this method is consistent with equals().

Specified by:

compareTo in interface java.lang.Comparable

Parameters:

obj - the object that this instance is to be compared to.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object, respectively.

Throws:

java.lang.ClassCastException - if the specified object's type prevents it from being compared to this instance.

toString

public java.lang.String toString()

Returns a string representing the current state of the object.

Overrides:

toString in class java.lang.Object

Returns:

the string representation of this instance.
