Class OAObjectGrid

java.lang.Object

com.viaoa.object.OAObjectGrid

public class OAObjectGrid
extends Object

Create a two dimensional (cols & rows) of data. Each column is given a property path to a link property, which can be type one or many.
Columns can be populated with:

• Hub
• single OAObject
• property path from another column (master/detail)
• Hub of Objects that can be grouped by another column.

The rows are then created to form a data grid (/table).

Method Detail

addColumn

public OAObjectGrid.Column addColumn(Hub hub)

addDetailColumn

public OAObjectGrid.Column addDetailColumn(OAObjectGrid.Column colFrom,
                                           String pp)

addGroupByColumn

public OAObjectGrid.Column addGroupByColumn(OAObjectGrid.Column colLeft,
                                            Hub hub,
                                            String pp,
                                            String matchPropName)

Create a LeftJoin relationship with another column (the "left").

Parameters:

colLeft - that is the linkLeft for hub to match to.

pp - propertyPath to link hub/object.

matchPropName - property in hub that links to colLeft.hub

getRootColumn

public OAObjectGrid.Column getRootColumn(OAObjectGrid.Column col)

getPropertyPathFromRoot

public String getPropertyPathFromRoot(OAObjectGrid.Column colParent,
                                      String pp)

verifyLinkProperty

public static boolean verifyLinkProperty(Class classFrom,
                                         String pp)

all column propertyPaths need to be for a link

getColumn

public OAObjectGrid.Column getColumn(int pos)

getColumnCount

public int getColumnCount()

getColumns
