Constructor Detail

TopLinkDefinition

public TopLinkDefinition()

Zero arg constructor required by the framework.

TopLinkDefinition

public TopLinkDefinition(DataControlStructure definition)

Constructor used by the BeanAbstractAdapter.

Method Detail

createDataControl

public DataControl createDataControl()

Creates data control at runtime.

Specified by:

createDataControl in class AbstractDefinition

Returns:

the data control instance.

getProviderType

protected java.lang.String getProviderType()

Returns the dc structure provider type for this BeanAbstractDefinition.

Specified by:

getProviderType in class BeanAbstractDefinition

isSupported

public boolean isSupported(java.lang.String operation)

Description copied from class: AbstractDefinition

Indicates if the adapter support things like sorting, transaction etc. Adapter data control definition should overwrite this method to provide the info specific to the data control instance.

Overrides:

isSupported in class AbstractDefinition

Parameters:

operation - one of the values defined in DataControlDefinition.

Returns:

boolean true if supported. The default implementation returns "false" for all flags.

assignDefaultPackage

public boolean assignDefaultPackage()

Description copied from class: AbstractDefinition

Data controls which do not already have their own package structure need to use a default package. Bean-based data controls, or others whose names embed their package structure, should override this to return false.

Overrides:

assignDefaultPackage in class AbstractDefinition

Returns:

false to indicate that TopLink data controls maintain their own package info in the structure defs they create.

getAdapterType

public java.lang.String getAdapterType()

Returns the name of the TopLinkAdapter class as the adapter type.

Overrides:

getAdapterType in class AbstractDefinition

Returns:

name of the corresponding adapter that matches this definition. If there is no adapter defined for this type, the method returns null. The default implementation returns null.
