Method Details

execute

public IResult execute(IProgressListener listener)
                throws Exception

Description copied from interface: IQuery

The execute method is called after all arguments have been injected into the query instance. Typical results are TextResult, CompositeResult, SectionSpec etc.

Specified by:

execute in interface IQuery

Parameters:

listener - Monitor to report progress and check for cancellation.

Returns:

The result of the query.

Throws:

Exception - if something went wrong running the query

getResultMetaData

public ResultMetaData getResultMetaData()

Description copied from interface: IResult

(Optionally) Return meta data of the result needed to fine-tune the display of the result. This could include an additional context, an additional query to run on selected data from the result , additional calculated columns, or an indication that the results are already presorted.

Specified by:

getResultMetaData in interface IResult

Returns:

the metadata for the result, used to obtain extra data

getColumns

public Column[] getColumns()

Description copied from interface: IStructuredResult

The columns of the tree or table.

Specified by:

getColumns in interface IStructuredResult

Returns:

an array of all the columns

getChildren

public List<?> getChildren(Object parent)

Description copied from interface: IResultTree

Returns the child elements of the given parent.

Specified by:

getChildren in interface IResultTree

Parameters:

parent - The row object as returned by the IResultTree.getElements() or IResultTree.getChildren(Object) methods.

Returns:

a list of children of this branch of the tree

getColumnValue

public Object getColumnValue(Object row,
 int columnIndex)

Description copied from interface: IStructuredResult

Returns the (unformatted) value of a table/tree cell.

Specified by:

getColumnValue in interface IStructuredResult

Parameters:

row - The row object as returned by the IResultTable.getRow(int) or IResultTree.getElements() or IResultTree.getChildren(Object) methods

columnIndex - The index of the column.

Returns:

the cell value

getElements

public List<?> getElements()

Description copied from interface: IResultTree

Returns the root elements of the tree.

Specified by:

getElements in interface IResultTree

Returns:

a list of all the root elements of the tree as opaque row objects representing each row which can be passed to IResultTree.getChildren(Object) or IStructuredResult.getContext(Object) or IStructuredResult.getColumnValue(Object, int).

hasChildren

public boolean hasChildren(Object parent)

Description copied from interface: IResultTree

Returns whether the given element has children.

Specified by:

hasChildren in interface IResultTree

Parameters:

parent - the opaque object used to indicate which branch

Returns:

true if this element has children

getContext

public IContextObject getContext(Object row)

Description copied from interface: IStructuredResult

The default context of the row which is used to display information in the object inspector. Unless no context provider is given via the ResultMetaData, it is also used for the context menu on a row.

Specified by:

getContext in interface IStructuredResult

Parameters:

row - The row object as returned by the IResultTable.getRow(int) or IResultTree.getElements() or IResultTree.getChildren(Object) methods.

Returns:

a context object holding details about that row

getContextProviders

public ContextProvider[] getContextProviders()
