Constructor Detail

CheckConstraint

public CheckConstraint(java.lang.String name,
                       Relation relation)

Constructs a new CheckConstraint on a relation with a specific name.

Parameters:

name - a string representing name of the constraint

relation - the relation being constrained

CheckConstraint

public CheckConstraint()

Creates a new CheckConstraint.

Method Detail

getConstraintType

public java.lang.String getConstraintType()

Description copied from class: Constraint

Retrieves the type of constraint represented by this instance. Valid constraint types can vary depending on the database. Examples of constraint types include primary key constraints, foreign key constraints, and check constraints.

Specified by:

getConstraintType in class Constraint

Returns:

a string value indicating the type of constraint.

getCheckCondition

@Deprecated
public java.lang.String getCheckCondition()

Deprecated. - use getCheckConditionFragment()

Retrieves the conditional expression represented by this constraint.

Returns:

a string containing the conditional expression

setCheckCondition

@Deprecated
public void setCheckCondition(java.lang.String condition)

Deprecated. - use setCheckConditionFragment(SQLFragment)

Sets the conditional expression represented by this constraint.

Parameters:

condition - a string containing the conditional expression

getCheckConditionFragment

public SQLFragment getCheckConditionFragment()

Retrieves the conditional expression represented by this constraint.

Returns:

a SQLFragment representing the conditional expression

setCheckConditionFragment

public void setCheckConditionFragment(SQLFragment condition)

Sets the conditional expression represented by this constraint.

Parameters:

condition - a SQLFragment representing the conditional expression

findOwnedObject

public DBObject findOwnedObject(DBObjectID id)

Description copied from class: AbstractDBObject

Returns a child of this object that has the given ID. The child is located by comparing IDs, not by calling resolveID() which is quicker. The method does not recurse to look for children of children. This method is a candidate for adding to the DBObject interface.

Specified by:

findOwnedObject in interface DBObject

Overrides:

findOwnedObject in class AbstractDBObject

Parameters:

id - the id to look for

Returns:

a child object found with that id.
