Constructor Detail

FKUsage

public FKUsage()

FKUsage

public FKUsage(DBObjectID fkID,
               DBObjectID leftID,
               DBObjectID rightID)

Method Detail

getObjectID

public DBObjectID getObjectID()

Gets the id of the FK being used in the SQL of this fragment.

Specified by:

getObjectID in interface DBObjectUsage

setObjectID

public void setObjectID(DBObjectID fkid)

Sets the id of the FK being used in the SQL of this fragment.

Specified by:

setObjectID in interface DBObjectUsage

getLeftFromObject

@Deprecated
public FromObject getLeftFromObject()

Deprecated. - use getLeftFromObjectID or resolveLeftFromObject

Returns:

setLeftFromObject

@Deprecated
public void setLeftFromObject(FromObject obj)

Deprecated. - use getLeftFromObjectID or resolveLeftFromObject

getLeftFromObjectID

public DBObjectID getLeftFromObjectID()

setLeftFromObjectID

public void setLeftFromObjectID(DBObjectID leftID)

getRightFromObjectID

public DBObjectID getRightFromObjectID()

setRightFromObjectID

public void setRightFromObjectID(DBObjectID rightID)

getRightFromObject

@Deprecated
public FromObject getRightFromObject()

Deprecated. - use getRightFromObjectID or resolveRightFromObject

Returns:

setRightFromObject

@Deprecated
public void setRightFromObject(FromObject obj)

Deprecated. - use setRightFromObjectID

resolveLeftFromObject

public FromObject resolveLeftFromObject()

Resolves the ID for the left From Object of this usage and writes any DBExceptions to the console -- do not use unless you are happy to ignore any DBExceptions.

Returns:

resolveRightFromObject

public FromObject resolveRightFromObject()

Resolves the ID for the left From Object of this usage and writes any DBExceptions to the console -- do not use unless you are happy to ignore any DBExceptions.

Returns:

getSQLText

public java.lang.String getSQLText()

Description copied from interface: SQLFragment

Return the SQL for this fragment. This contains no validation - if the implementation is incomplete it will just return what it has. Error checking of fragments should be done using a SQLQueryBuilder.

Specified by:

getSQLText in interface SQLFragment

Returns:

a string representing the SQL text for this object.

setProvider

public void setProvider(DBObjectProvider pro)

Description copied from interface: ProviderUsage

Sets the provider this usage exists within. The provider is used to convert names to external versions when creating the SQL for the fragment. Without this set names will not be quoted when appropriate.

Specified by:

setProvider in interface ProviderUsage

copyToImpl

protected void copyToImpl(AbstractDBObject target,
                          DBObject copyParent,
                          IDPolicy idPolicy)

Description copied from class: AbstractDBObject

Implementation method for making a copy of this object. To add custom copyTo logic, a subclass must override this method (exactly), and must call back to the super implementation.

Overrides:

copyToImpl in class AbstractChildDBObject

Parameters:

target - the copy being created of this object

copyParent - if this object is being copied underneath a parent, this parameter is the copy of the parent of this object, which will therefore need to be the parent of the copy of this object.

idPolicy - the policy for copying the object's ID.
