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

See Also:

DBObject.copyTo(java.lang.Object), DBObject.copyTo(DBObject, boolean), AbstractDBObject.copyToImpl(oracle.javatools.db.AbstractDBObject, oracle.javatools.db.DBObject, oracle.javatools.db.IDPolicy)

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
