Constructor Detail

AbstractFromObjectUsage

protected AbstractFromObjectUsage()

AbstractFromObjectUsage

@Deprecated
protected AbstractFromObjectUsage(FromObject from)

Deprecated. - use ID based constructor instead

Parameters:

from -

AbstractFromObjectUsage

protected AbstractFromObjectUsage(DBObjectID fromId)

Parameters:

fromId -

Method Detail

setFromObject

@Deprecated
public void setFromObject(FromObject from)

Deprecated. - use setFromObjectID() instead

Sets the FromObject that this ColumnUsage is dependent on.

Specified by:

setFromObject in interface FromObjectUsage

getFromObject

@Deprecated
public FromObject getFromObject()

Deprecated. - use setFromObjectID() instead

Gets the FromObject that this ColumnUsage is dependent on.

Specified by:

getFromObject in interface FromObjectUsage

resolveFromObject

public FromObject resolveFromObject()

Convenience method for resolving the stored FROM object id. Catches any DBExceptions and writes them to the console. Do not use if you are interested in DBExceptions.

Specified by:

resolveFromObject in interface FromObjectUsage

Returns:

resolveFromObject

protected FromObject resolveFromObject(DBObjectID fromId)

findFragmentInQuery

protected DBObject findFragmentInQuery(DBObjectID id)

Finds the object that has the given id within the fragment heirachy of this fragment. All parent queries will be searched to find the fragment object.

Parameters:

id - of the object to find

Returns:

the object if it is within the heirachy of any parent SQLQuery

setFromObjectID

public void setFromObjectID(DBObjectID id)

Sets the DBObjectID for the FromObject that is used by this fragment.

Specified by:

setFromObjectID in interface FromObjectUsage

Parameters:

id - the DBObjectID for a FromObject in the same SQLQuery as this fragment.

getFromObjectID

public DBObjectID getFromObjectID()

Gets the DBObjectID for the FromObject that is used by this fragment.

Specified by:

getFromObjectID in interface FromObjectUsage

Returns:

the DBObjectID for a FromObject in the same SQLQuery as this fragment.

setQualified

public void setQualified(boolean qualified)

Sets wether this column usage should qualify itself with the alias from its FromObject. e.g. EMP.ENAME rather than ENAME

Specified by:

setQualified in interface FromObjectUsage

isQualified

public boolean isQualified()

Gets wether this column usage should qualify itself with the alias from its FromObject. e.g. EMP.ENAME rather than ENAME

Specified by:

isQualified in interface FromObjectUsage

getSQLTextImpl

protected java.lang.StringBuilder getSQLTextImpl()

Default implementation of getSQLText() which returns a StringBuilder containing the from object name (if there is one and we're qualified) DOT the column name.
