Specified by:
getM4TableName in interface M4Table
See Also:
M4Table.getM4TableName()

getIdAttributeName

public java.lang.String getIdAttributeName()
Specified by:
getIdAttributeName in interface M4Table
See Also:

getM4Info

public M4Info getM4Info()
Specified by:
getM4Info in interface M4Table
See Also:
M4Table.getM4Info()

getXmlInfo

public M4Info getXmlInfo()
Specified by:
getXmlInfo in interface XmlInfo
Returns:
a M4Info object with the information of all XML fields of this object.
See Also:

print

public void print()
Description copied from interface: M4Object
Method to print data about this M4Object.

Specified by:
print in interface M4Object
Specified by:
print in class M4Object
See Also:
M4Object.print()

getObjectsInNamespace

protected java.util.Collection getObjectsInNamespace(java.lang.Class typeOfObjects)
                                              throws M4Exception
Description copied from class: M4Data
This method returns the objects of the specified type that form a namespace in the scope of this M4Data object. For example, a Concept's namespace for the type BaseAttribute is the Collection of all BaseAttributes for this Concept. Many M4Data objects never have a namespace, they return null. If a namespace could exist but doesn't, an empty Collection is returned.

Specified by:
getObjectsInNamespace in class M4Data
Parameters:
typeOfObjects - the type of objects that form the namespace
Returns:
a Collection of objects of type typeOfObjects, or null.
Throws:
M4Exception
See Also:
M4Data.getObjectsInNamespace(Class)

public java.lang.String getObj1()
Gets the myObj1.

Specified by:
getObj1 in interface Constraint
Returns:
Returns a String

getObj2

public java.lang.String getObj2()
Gets the myObj2.

Specified by:
getObj2 in interface Constraint
Returns:
Returns a String

getTheOperator

public Operator getTheOperator()
Gets the Operator

Specified by:
getTheOperator in interface Constraint
Returns:
Returns an Operator

getType

public java.lang.String getType()
Gets the myType.

Specified by:
getType in interface Constraint
Returns:
Returns a String

setObj1

Specified by:
setObj2 in interface Constraint
Parameters:
myObj2 - The myObj2 to set

setTheOperator

public void setTheOperator(Operator operator)
                    throws M4Exception
Sets the Operator.
