Method Detail

getInstance

public static ColumnType getInstance(java.lang.String displayName)

getInstance

public static ColumnType getInstance(int value)

getDisplayName

public java.lang.String getDisplayName()

Return the display name for this type.

Returns:

the display name

compareTo

public int compareTo(java.lang.Object obj)

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

Note: this method is consistent with equals(), meaning that (compare(x, y)==0) == (x.equals(y)).

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.IllegalArgumentException - if the specified object reference is null

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

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.

hashCode

public final int hashCode()

Returns the hash code value for this object.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.

toString

public final 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.
