All Implemented Interfaces:

PropertyEditorTarget, java.io.Serializable, javax.swing.tree.TreeNode

public class DBMetaSchemaNode

extends ReverseDbTreeNode

implements java.io.Serializable

This node represents a schema of the database. Its children are DBMetaTableNode objects. Not all databases support schemas (e.g. MySQL), so the schema name may be null.

Constructor Detail

DBMetaSchemaNode

public DBMetaSchemaNode(java.sql.DatabaseMetaData pdbMeta,
                        DatabaseMetaDataTreeModel pdbMetaTreeModel,
                        DBMetaCatalogNode pcatalogNode,
                        java.lang.String pstrSchemaName)

Creates a new instance of DBMetaSchemaNode

Parameters:

pdbMeta - DatabaseMetaData implementation where this node gets its data from.

pdbMetaTreeModel - The TreeModel this node is associated to.

pcatalogNode - The parent node for this node.

pstrSchemaName - The name of the schema this node is representing. Some databases do not support schemas, therefore null values are allowed for this parameter

Method Detail

getAllowsChildren

public boolean getAllowsChildren()

Specified by:

getAllowsChildren in interface javax.swing.tree.TreeNode

Specified by:

getAllowsChildren in class ReverseDbTreeNode

See Also:

ReverseDbTreeNode.isLeaf()

isLeaf

public boolean isLeaf()

Specified by:

isLeaf in interface javax.swing.tree.TreeNode

Specified by:

isLeaf in class ReverseDbTreeNode

See Also:

ReverseDbTreeNode.getAllowsChildren()

getSchemaName

public java.lang.String getSchemaName()

Convenience access method for the schema name. Accesses the attributes HashMap to retrieve the value.

toString

public java.lang.String toString()

If the schema name is specified, returns the schema name, otherwise a constant string indicating that the schema name is emtpy (which is legal for some databases, e.g. MySQL)

See Also:

Object.toString()

getCatalog

public DBMetaCatalogNode getCatalog()

Convenience access method to the catalog this schema is associated to.

getPropertyEditorClass

public java.lang.Class getPropertyEditorClass()

Description copied from interface: PropertyEditorTarget

Return the property editor class for this PropertyEditorTarget. Depending on the GUI implementation this could for example be an extension of JPanel. The Property editor is responsible for the layout, so the property editor has to know which properties this target has.

Specified by:

getPropertyEditorClass in interface PropertyEditorTarget

_load

protected boolean _load()

Fills the children list with the tables this schema contains.

Specified by:

_load in class ReverseDbTreeNode
