Method Summary

boolean	equals(Object term) Term objects may be used in hashes and should provide an efficient equals method.
Integer	getIndex() Method to extract the Integer index for this Term.
String	getKey() Method to extract the String key for this Term.
int	hashCode() Term objects may be used in nlists.
boolean	isKey() A utility function to determine if this Term is a key (String value).
String	toString() This method must return a String representation of the Term object.

Method Detail

isKey

boolean isKey()

A utility function to determine if this Term is a key (String value).

Returns:

boolean indicating if this Term is a key

getIndex

Integer getIndex()
                 throws InvalidTermException

Method to extract the Integer index for this Term. This will throw an exception if the Term is not an index.

Returns:

Integer index of the Term

Throws:

InvalidTermException - thrown if the term is not an index; message should contain the string value of the term that was used

getKey

String getKey()
              throws InvalidTermException

Method to extract the String key for this Term. This will throw an exception if the Term is not a key.

Returns:

String key of the Term

Throws:

InvalidTermException - thrown if the term is not a key; message should contain the string value of the term that was used

hashCode

int hashCode()

Term objects may be used in nlists. Consequently, implementations should provide a highly-efficient hashCode method.

Overrides:

hashCode in class Object

Returns:

hash code for this Term

equals

boolean equals(Object term)

Term objects may be used in hashes and should provide an efficient equals method.

Overrides:

equals in class Object

Returns:

boolean indicating whether two objects are equal

toString

String toString()

This method must return a String representation of the Term object. It must be exactly the same String which would be returned by the underlying value.

Overrides:

toString in class Object
