Class BaseDBObjectTextNode

java.lang.Object

oracle.ide.model.Node

oracle.ide.model.TextNode

oracle.ide.db.model.BaseDBObjectTextNode

All Implemented Interfaces:

DBObjectNode, DBObjectProviderNode, DBObjectTypeNode, Displayable, Element, LazyLoadable, Locatable, Subject, Dirtyable

Direct Known Subclasses:

BasePlSqlTextNode

public abstract class BaseDBObjectTextNode
extends TextNode
implements DBObjectNode

Convenience subclass of TextNode that implements DBObjectNode. Client code should not register against, or rely on this class. Where possible use the interface. For PL/SQL there is another subclass that specifically implements DBObjectPlSqlNode.

Methods

Modifier and Type	Method and Description
void	cancelCurrentBuild() If the object requested by a call to getDBObject( Mode.BUILT ) is currently being built, this will request that process is cancelled.
protected SourceObject	findProviderDBObject() Returns the instance of the DBbject this node represents that is owned by the provider.
DBObject	getDBObject() Returns the DBObject for the node.
SourceObject	getDBObject(boolean fullyBuilt) Return a SourceObject whose source matches the current contents of the TextBuffer.
javax.swing.Icon	getIcon() Default implementation of this Displayable method returns the appropriate icon for the object's type.
DBObjectProvider	getProvider() Gets the provider from the DBObjectProviderFactory using the key returned by getProviderIdentifier().
java.lang.String	getProviderType() By default this returns "db".
java.lang.String	getShortLabel() Default implementation of this Displayable method returns the object name.
protected void	openImpl() Subclasses should override this method to customize the open() behavior.
protected void	resetBuffer(SourceObject obj) Aquires the TextBuffer and resets its contents to match the source on the given SourceObject.
protected void	updateSource(SourceObject so, java.lang.String source) Sets the source on the SourceObject.

BaseDBObjectTextNode

public BaseDBObjectTextNode()

Method Detail

getProviderType

public java.lang.String getProviderType()

By default this returns "db". Override if needed.

Specified by:

getProviderType in interface DBObjectProviderNode

getDBObject

public DBObject getDBObject()

Returns the DBObject for the node. This abstract implementation gets the node from the provider and will therefore hit the database. If possible override in a subclass.

Specified by:

getDBObject in interface DBObjectNode

getProvider

public DBObjectProvider getProvider()

Gets the provider from the DBObjectProviderFactory using the key returned by getProviderIdentifier().

Specified by:

getProvider in interface DBObjectNode

See Also:

DBObjectTypeNode.getProviderIdentifier()

getIcon

public javax.swing.Icon getIcon()

Default implementation of this Displayable method returns the appropriate icon for the object's type.

Specified by:

getIcon in interface Displayable

Overrides:

getIcon in class Node

Returns:

the Icon to be displayed for the Displayable.

getShortLabel

public java.lang.String getShortLabel()

Default implementation of this Displayable method returns the object name.

Specified by:

getShortLabel in interface Displayable

Overrides:

getShortLabel in class Node

Returns:

a short descriptive label of the Displayable that can be shown to the user.

openImpl

protected void openImpl()
                 throws java.io.IOException

Description copied from class: Node

Subclasses should override this method to customize the open() behavior. Node.open() invokes this only if the node is not open, under write lock. The Node implementation does nothing.

Overrides:

openImpl in class TextNode

Throws:

java.io.IOException - if an I/O error occurred while opening

getDBObject

public final SourceObject getDBObject(boolean fullyBuilt)

Return a SourceObject whose source matches the current contents of the TextBuffer.

See Mode for more details.

cancelCurrentBuild

public final void cancelCurrentBuild()

If the object requested by a call to getDBObject( Mode.BUILT ) is currently being built, this will request that process is cancelled. Does nothing otherwise.

findProviderDBObject

protected SourceObject findProviderDBObject()

Returns the instance of the DBbject this node represents that is owned by the provider.

updateSource

protected void updateSource(SourceObject so,
                java.lang.String source)

Sets the source on the SourceObject.

Parameters:

so - The Source Object

source - The source

resetBuffer

protected void resetBuffer(SourceObject obj)

Aquires the TextBuffer and resets its contents to match the source on the given SourceObject. Called when the object is changed and the Node/TextBuffer must be changed to keep sync.

Parameters:

obj - the object with the correct source that the text buffer should match
