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.
getConditionText
public java.lang.String getConditionText()
- Description copied from interface:
JoinCondition
- Returns the condition text - this is the sql text without the condition
keyword.
- Specified by:
getConditionText
in interface JoinCondition
copyTo
public DBObject copyTo(DBObject target,
DBObject copyParent,
IDPolicy idPolicy)
- Description copied from class:
AbstractDBObject
- Internal copy method used by the API to perform copy operations. All
objects must implement this method if they are instantiable objects.
Abstract objects (e.g. Relation) must NOT implement this method. The
implementation should delegate to the copyToImpl method to copy
the actual properties.
This method does not fix internal reference ids on copy. That is done by
the calling DBObject.copyTo(DBObject, IDPolicy)
method.
- Specified by:
copyTo
in class AbstractDBObject
