Class DBObjectNodeUtil

java.lang.Object
  oracle.ide.db.model.DBObjectNodeUtil

public final class DBObjectNodeUtil
extends java.lang.Object

Utility methods for dealing with DBObjectNode instances. The various methods can make the job of handling DnD of nodes easier by providing quick test methods to see if the object in question is a valid node that matches a given object type. Specific tests are also provided for Relations as they could be objects of a number of types.

Method Detail

isNodeOfType

public static boolean isNodeOfType(java.lang.String type,
                                   java.lang.Object node)

Returns true if the given object is a valid DBObjectNode that contains an object with the given type.

Parameters:

type - the type of object we're looking for

node - the node to test for the object

Returns:

true if there's a match.

isOnlineNodeOfType

public static boolean isOnlineNodeOfType(java.lang.String type,
                                         java.lang.Object node)

Returns true if the given object is a valid DBObjectNode that contains an object with the given type AND that object has come from a live (online) database connection.

Parameters:

type - the type of object we're looking for

node - the node to test for the object

Returns:

true if there's a match.

isOnlineNode

public static boolean isOnlineNode(java.lang.Object node)

Returns true if the given object is a valid DBObjectNode that has come from a live (online) database connection.

Parameters:

node - the node to test for the object

Returns:

true if there's a match.

isRelationNode

public static boolean isRelationNode(java.lang.Object node)

Returns true if the given object is a valid DBObjectNode that contains a Relation object (i.e. Table, View or Materialized View).

Parameters:

node - the node to test for a Relation

Returns:

true if there's a match.

isNodeOfType(java.lang.String, java.lang.Object)

isRelationNode

public static boolean isRelationNode(java.lang.Object node,
                                     boolean unwrapSynonym)

Returns true if the given object is a valid DBObjectNode that contains a Relation object (i.e. Table, View or Materialized View).

Parameters:

node - the node to test for a Relation

unwrapSynonym - resolve referenced object for Synonyms

Returns:

true if there's a match.

isNodeOfType(java.lang.String, java.lang.Object)

isSynonymNode

public static boolean isSynonymNode(java.lang.Object node)

isOnlineRelationNode

public static boolean isOnlineRelationNode(java.lang.Object node)

Returns true if the given object is a valid DBObjectNode that contains a Relation object (i.e. Table, View or Materialized View) AND that Relation has come from a live (online) database connection.

Parameters:

node - the node to test for a Relation

Returns:

true if there's a match.

isOnlineNodeOfType(java.lang.String, java.lang.Object)

isOnlineRelationNode

public static boolean isOnlineRelationNode(java.lang.Object node,
                                           boolean unwrapSynonym)

Returns true if the given object is a valid DBObjectNode that contains a Relation object (i.e. Table, View or Materialized View) AND that Relation has come from a live (online) database connection.

Parameters:

node - the node to test for a Relation

unwrapSynonym - resolve referenced object for Synonyms

Returns:

true if there's a match.

isOnlineNodeOfType(java.lang.String, java.lang.Object)

getStoreName

public static java.lang.String getStoreName(java.lang.Object node)

Returns the name of the store if it is retrievable from the given object (node). This is not a full proof way of getting a store because some Views have an implicit store.

Parameters:

node - the node to to check

Returns:

the name of the store if implied by the node

See Also:

DatabaseConnectionStores.getCurrentStore()

getConnectionName

public static java.lang.String getConnectionName(java.lang.Object node)

Returns the name of the connection if it is retrievable from the given object (node).

Parameters:

node - the node to to check

Returns:

the name of the store if implied by the node

See Also:

DatabaseConnectionStores.getCurrentConnection(oracle.ide.Context)

decode

public static java.lang.String decode(java.lang.String name,
                                      boolean store)

Decodes the given String to get out the connection name (or alternatively store name). If the decoded string contains a '#' it is assumed that the store name preceeds it, and the connection name follows it.

Parameters:

name - the string to decode

store - if true, on decoding the string the store name is returned.

Returns:
