Constructor Detail

DeployTableJoinColumn

public DeployTableJoinColumn(String localDbColumn,
                     String foreignDbColumn)

Construct when automatically determining the join.

Assume that we want the foreign key to be insertable and updateable.

DeployTableJoinColumn

public DeployTableJoinColumn(String localDbColumn,
                     String foreignDbColumn,
                     boolean insertable,
                     boolean updateable)

Construct with explicit insertable and updateable flags.

DeployTableJoinColumn

public DeployTableJoinColumn(boolean order,
                     javax.persistence.JoinColumn jc,
                     BeanTable beanTable)

Method Detail

reverse

public DeployTableJoinColumn reverse()

Reverse the direction of the join.

copy

public DeployTableJoinColumn copy(boolean reverse)

toString

public String toString()

Overrides:

toString in class Object

hasNullColumn

public boolean hasNullColumn()

Return true if either the local or foreign column is null.

Both columns need to be defined. If one is null then typically it is derived as the primary key column.

getNonNullColumn

public String getNonNullColumn()

When only ONE column has been set by deployment information return that one.

Used with hasNullColumn() to set the foreignDbColumn for OneToMany joins.

isInsertable

public boolean isInsertable()

Return true if this column should be insertable.

isUpdateable

public boolean isUpdateable()

Return true if this column should be updateable.

getForeignDbColumn

public String getForeignDbColumn()

Return the foreign database column name.

setForeignDbColumn

public void setForeignDbColumn(String foreignDbColumn)

Set the foreign database column name.

Used when this is derived from Primary Key and not set explicitly in the deployment information.

getLocalDbColumn

public String getLocalDbColumn()

Return the local database column name.

setLocalDbColumn

public void setLocalDbColumn(String localDbColumn)

Set the local database column name.
