java.lang.Objectoracle.adf.model.adapter.AbstractDefinition
public abstract class AbstractDefinition
Definition of a data control instance.
There are several ways that this class can be generated.
load
to load from the metadata definition.
Once the definition is loaded, it calls the createDataControl()
to
create the data control instance.
Note: When the definition loaded at the runtime, runtime sets the name
of the definition as stored in the metadata. The implementation of this
class MUST use getName()
to get the name of the definition.

boolean |
assignDefaultPackage()
Data controls which do not already have their own package structure need to use a default package. |
abstract DataControl |

abstract StructureDefinition |
getStructure()
Gets the structure definition of the output data. |
boolean |
isStructureDirty(boolean refresh)
The implementation should return true if the structure of the back end data is changed. |
boolean |
isSupported(java.lang.String flag)
Indicates if the adapter support things like sorting, transaction etc. |

loadFromMetadata(Node node,
java.util.Map params)
Loads the definition from a metadata Node . |

shouldStoreStructureDefinition()
Deprecated. use |
boolean |
usePersistedStructure()

node
- the metadata node. It can be null if no metadata is defined.params
- context parameters.public abstract DataControl createDataControl()
protected abstract java.lang.String getDCName()
public java.lang.String getAdapterType()
AdapterDefinition
public java.lang.String getDefClassName()
The framework will call this method at the design time to store the definition class name that will load the metadata. The returned class must be a derived class of this astract class. The default implementation returns the class name of this instance only. The derived class needs to override this only if the definition class that may load a metadata is different than this instance.
public boolean shouldStoreStructureDefinition()
getStructure()
should be serialized.
If this method returns "true", the structure definitions get serialized at the design time and get loaded at the runtime by the framework.
The default implementation return "true".
public boolean usePersistedStructure()
public boolean isStructureDirty(boolean refresh)
getStructure()
is this
method returns false.
refresh
- flag to indicate if the refresh is requested for the
structure.
public ParameterDefinition[] getParameters()
The implementation should override this method if the definition uses parameters. The default implementatiaon returns null.
public java.lang.String getName()
At runtime, the name is set from the metadata information. At
design time it calls getDCName()
to get the name of this
definition.
getName
in interface NamedDefinition
public boolean isSupported(java.lang.String flag)
flag
- one of the values defined in
DataControlDefinition
.
public boolean assignDefaultPackage()
public boolean shouldCompileProjectOnCreate()
Note:
If the data control create is invoked from within a UI operation (e.g. you
are invoking creation of data control while responding to a property change
action of the data control metadata), this method must return false.
A data control can be created by calling the method
createDataControl
on class MetaDef
.
