Constructor Detail

AttrValue

public AttrValue()

Constructor.

AttrValue

public AttrValue(AttrValue src)

Copy constructor.

Parameters:

src - The AttrValue to be copied.

AttrValue

public AttrValue(byte aType)

Constructor.

Parameters:

aType - The type of AttrValue this object will be.

Method Detail

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Clones this AttrValue.

Overrides:

clone in class java.lang.Object

Returns:

The Clone of this AttrValue.

Throws:

java.lang.CloneNotSupportedException - This exception is never thrown by this class and is only present because Java's Object class requires it.

gets

public void gets(AttrValue src)

Sets this AttrValue to the same values as the specified AttrValue.

Parameters:

src - The AttrValue containing values to be copied.

equals

public boolean equals(AttrValue a)

Compares this AttrValue to the specified AttrValue. Base class AttrValues cannot be compared. Displays an error message if attempted.

Parameters:

a - The AttrValue to be compared to.

Returns:

TRUE if equal, FALSE otherwise. Always FALSE for the AttrValue base class.

attr_type_to_string

public java.lang.String attr_type_to_string(byte attrType)

Converts the specified AttrValue type to a String.

Parameters:

attrType - The specific value to be converted to a String.

Returns:

The String representing this AttrValue.

toString

public java.lang.String toString()

Converts the specified AttrValue to a String.

Overrides:

toString in class java.lang.Object

Returns:

A String representing the value stored in this AttrValue.

copy

public void copy(AttrValue other)

Copies information from the supplied AttrValue to this AttrValue.

Parameters:

other - The AttrValue to be copied.
