Class AbstractSemanticIdentifier

java.lang.Object

gov.sandia.cognition.framework.AbstractSemanticIdentifier

All Implemented Interfaces:

SemanticIdentifier, java.io.Serializable, java.lang.Comparable<SemanticIdentifier>

Direct Known Subclasses:

DefaultSemanticIdentifier

public abstract class AbstractSemanticIdentifier
extends java.lang.Object
implements SemanticIdentifier

The AbstractSemanticIdentifier class implements the basic methods that are needed for a SemanticIdentifier to provide a good speed improvement. In particular, it makes use of the getIdentifier method to use the identifier in the hashCode and equals fuctions in order to make them fast.

Since:

1.0

Method Detail

hashCode

public int hashCode()

Computes the hash-code for the SemanticIdentifier, which should be equal to a call to getIdentifier.

Specified by:

hashCode in interface SemanticIdentifier

Overrides:

hashCode in class java.lang.Object

Returns:

The hash code of the identifier, which is the identifier number.

compareTo

public int compareTo(SemanticIdentifier o)

Specified by:

compareTo in interface SemanticIdentifier

Specified by:

compareTo in interface java.lang.Comparable<SemanticIdentifier>

Parameters:

o -

Returns:

equals

public boolean equals(java.lang.Object other)

Determines if this identifier is equal to another Object. If that Object is a SemanticIdentifier then the two are equal if the identifier numbers are the same.

Specified by:

equals in interface SemanticIdentifier

Overrides:

equals in class java.lang.Object

Parameters:

other - The Object to test equality with.

Returns:

True if this is equal to the given Object.

equals

public boolean equals(SemanticIdentifier other)

Determines if this identifier is equal to the given one by comparing the identifier number only. This comparison is invalid if the two labels come from different models.

Specified by:

equals in interface SemanticIdentifier

Parameters:

other - The other SemanticIdentifier to compare to.

Returns:

True if the two semantic identifiers are equal.
