Constructor Detail

Port.Info

public Port.Info(Class<?> klass,
                 String name,
                 boolean isSource)

Parameters:
klass - the class of the line
name - the name of the line
isSource - true if this is an input source
Method Detail

equals

public final boolean equals(Object o)
Description copied from class: Object
Determine whether this Object is semantically equal to another Object.

There are some fairly strict requirements on this method which subclasses must follow:

This is typically overridden to throw a ClassCastException if the argument is not comparable to the class performing the comparison, but that is not a requirement. It is legal for a.equals(b) to be true even though a.getClass() != b.getClass(). Also, it is typical to never cause a NullPointerException.

In general, the Collections API (java.util) use the equals method rather than the == operator to compare objects. However, IdentityHashMap is an exception to this rule, for its own good reasons.

The default implementation returns this == o.

Overrides:
equals in class Object
Parameters:
o - the Object to compare to
Returns:
whether this Object is semantically equal to another

Object.hashCode()

hashCode

public final int hashCode()
Description copied from class: Object
Get a value that represents this Object, as uniquely as possible within the confines of an int.

There are some requirements on this method which subclasses must follow:

Notice that since hashCode is used in Hashtable and other hashing classes, a poor implementation will degrade the performance of hashing (so don't blindly implement it as returning a constant!). Also, if calculating the hash is time-consuming, a class may consider caching the results.

The default implementation returns System.identityHashCode(this)

Overrides:
hashCode in class Object
Returns:
the hash code for this Object
See Also:
Object.equals(Object), System.identityHashCode(Object)

getName

public String getName()
Return the name of this object.


isSource

public boolean isSource()
Return true if this describes an input line.


matches

public boolean matches(Line.Info other)
Description copied from class: Line.Info
Return true if this Info object matches the given object.

Overrides:
matches in class Line.Info
Parameters:
other - the object to match
Returns:
true if they match, false otherwise

toString

public final String toString()
Description copied from class: Line.Info
Return a description of this Info object.

Overrides:
toString in class Line.Info
Returns:
the String representing this Object, which may be null

Object.getClass(), Object.hashCode(), Class.getName(), Integer.toHexString(int)
