Method Detail

getDef

public oracle.jbo.server.DefObject getDef()

Description copied from class: ComponentObjectImpl

Gets the Def Object.

Returns:

The DefObject this references.

isEntireObjectTable

public boolean isEntireObjectTable()

setEntireObjectTable

public void setEntireObjectTable(boolean b)

setReference

public void setReference(boolean state)

Set the Referant Entity to REFERENCE-ONLY enable entity lookup on source key attribute change.

Parameters:

state - True to be REFERENCE, false otherwise.

setReadOnly

public void setReadOnly(boolean state)

Set the Referant Entity to READ-ONLY entity usage

Parameters:

state - True to be READONLY , false otherwise.

isReference

public boolean isReference()

Does this Referant Entity participate in the DML.

Returns:

true if it does participate, false otherwise.

findViewAttrDefByViewAttrName

protected ViewAttributeDefImpl findViewAttrDefByViewAttrName(java.lang.String name,
                                                             AttributeDefImpl attr)

findViewAttrDefByBaseAttrName

protected ViewAttributeDefImpl findViewAttrDefByBaseAttrName(java.lang.String name,
                                                             AttributeDefImpl attr)

findViewAttributeDefImpl

protected ViewAttributeDefImpl findViewAttributeDefImpl(java.lang.String name)

findViewAttributeDefImpls

protected java.util.ArrayList findViewAttributeDefImpls(AttributeDefImpl attr)

isReadOnly

public boolean isReadOnly()

writeObject

public void writeObject(DefWriter jos)

Description copied from interface: PersistentDefinition

Objects should write their persistence output in this method

Specified by:

writeObject in interface PersistentDefinition

Parameters:

jos - the Output storage for persistence

writeContents

public void writeContents(DefWriter jos)

Description copied from interface: PersistentDefinition

Objects should write their persistence output in this method

Specified by:

writeContents in interface PersistentDefinition

Parameters:

jos - the Output storage for persistence

writeChildren

public void writeChildren(DefWriter jos)

Description copied from interface: PersistentDefinition

Writes the Object's children to the Persistent storage

Specified by:

writeChildren in interface PersistentDefinition

Parameters:

jos - the Output storage for persistence

getXMLElementTag

public java.lang.String getXMLElementTag()

Description copied from interface: PersistentDefinition

Returns a piece of static info for the type of object this is invoked upon. Examples are PreparedStatements for insert, update, delete, and String containing a base the select statement for retrieving instances of this type through the SQLInputStream

Specified by:

getXMLElementTag in interface PersistentDefinition

Returns:

returns the Statement required to store in Persitent Storage. Incase of XML, it just returns the String. In the case of SQL a JDBC PreparedStatement is returned.

getDefXMLElementTag

public java.lang.String getDefXMLElementTag()

Specified by:

getDefXMLElementTag in interface PersistentDefinition

getDefXMLNameSpace

public java.lang.String getDefXMLNameSpace()

Specified by:

getDefXMLNameSpace in interface PersistentDefinition

setJoinType

public void setJoinType(int joinType)

Set the type of join. Valid values are the constants INNER_JOIN, LEFT_OUTER_JOIN, RIGHT_OUTER_JOIN and FULL_OUTER_JOIN. This setting is used to detect if the Entity Reference could be empty in a View Row. It does not effect the generation of SQL because it is done by the design time. For effecting the runtime SQL use the methods setFromClause and setWhereClause on the ViewDefImpl class.

Parameters:

joinType - The type of join

getJoinType

public int getJoinType()

Returns the join type if the Entity Reference participates in one.

Returns:

constant values NONE_JOIN_TYPE, INNER_JOIN_TYPE, LEFT_OUTER_JOIN_TYPE, RIGHT_OUTER_JOIN_TYPE or FULL_OUTER_JOIN_TYPE

getJoinTypeAsString

public static java.lang.String getJoinTypeAsString(int joinType)

Returns the join type as a String so that it can be used in SQL generation.

Returns:

a String object

getJoinType

public static int getJoinType(java.lang.String type)

isEffectiveDated

public boolean isEffectiveDated()

Checks if the underlying entity is used in an effective dated fashion or not. It is possible to query in all the effective dated entities irrespective of their start and end effective dates by turning off date effectivity in the usage. Once queried in, the entity will continue to exhibit its effective dated nature when updates are made.

Returns:

true if the usage is effective dated, <false> otherwise.
