Constructor Detail

TapMetaTreeModel

public TapMetaTreeModel(SchemaMeta[] schemas,
                        TapMetaOrder order)

Constructs a tree model to display a given table set. Note this may reorder the schemas array in place, and the table ordering within each schema.

Parameters:

schemas - schema array defining the table metadata to be represented

order - initial ordering policy for contents

Method Detail

setSchemas

public void setSchemas(SchemaMeta[] schemas)

Sets the content of this tree. Note this may reorder the schemas array in place, and the table ordering within each schema.

Parameters:

schemas - schema array defining the table metadata to be represented

getOrder

public TapMetaOrder getOrder()

Returns the node ordering being used by this model.

Returns:

ordering

setOrder

public void setOrder(TapMetaOrder order)

Sets the node ordering to be used by this model.

Parameters:

order - ordering

getSchemas

public SchemaMeta[] getSchemas()

Returns the schemas array that forms the root of this tree model.

Returns:

schema array

getPathForTableName

public TreePath getPathForTableName(String tname)

Returns the path in this tree that corresponds to a given table name.

Parameters:

tname - table name

Returns:

path in tree corresponding to table name, or null

getTable

public static TableMeta getTable(TreePath path)

Acquires the table metadata object, if any, associated with a given tree path.

Parameters:

path - tree path associated with an instance of this class

Returns:

associated TableMeta object, or null

getSchema

public static SchemaMeta getSchema(TreePath path)

Acquires the schema metadata object, if any, associated with a given tree path.

Parameters:

path - tree path associated with an instance of this class

Returns:
