Method Detail

detailValue

public static 
IObservableValue detailValue(
IObservableValue master,
                                           
IObservableFactory detailFactory,
                                           
Object detailType)

Creates a detail observable value from a master observable value and a factory. This can be used to create observable values that represent a property of a selected object in a table.

Parameters:: master - the observable value to track; detailFactory - a factory for creating IObservableValue instances given a current value of the master; detailType - the value type of the detail observable value, typically of type java.lang.Class and can be null
Returns:: an observable value of the given value type that, for any current value of the given master value, behaves like the observable value created by the factory for that current value.

detailList

public static 
IObservableList detailList(
IObservableValue master,
                                         
IObservableFactory detailFactory,
                                         
Object detailElementType)

Creates a detail observable list from a master observable value and a factory. This can be used to create observable lists that represent a list property of a selected object in a table.

Parameters:: master - the observable value to track; detailFactory - a factory for creating IObservableList instances given a current value of the master; detailElementType - the element type of the detail observable list, typically of type java.lang.Class and can be null
Returns:: an observable list with the given element type that, for any current value of the given master value, behaves like the observable list created by the factory for that current value.

detailSet

public static 
IObservableSet detailSet(
IObservableValue master,
                                       
IObservableFactory detailFactory,
                                       
Object detailElementType)

Creates a detail observable set from a master observable value and a factory. This can be used to create observable sets that represent a set property of a selected object in a table.

Parameters:: master - the observable value to track; detailFactory - a factory for creating IObservableSet instances given a current value of the master; detailElementType - the element type of the detail observable set, typically of type java.lang.Class and can be null
Returns:: an observable set with the given element type that, for any current value of the given master value, behaves like the observable set created by the factory for that current value.

detailMap

public static 
IObservableMap detailMap(
IObservableValue master,
                                       
IObservableFactory detailFactory)

Creates a detail observable map from a master observable value and a factory. This can be used to create observable maps that represent a map property of a selected object in a table.

Parameters:: master - the observable value to track; detailFactory - a factory for createing IObservableMap instances given a current value of the master
Returns:: an observable map that, for any current value of the given master value, behaves like the observable map created by the factory for that current value.
Since:: 1.1

detailMap

public static 
IObservableMap detailMap(
IObservableValue master,
                                       
IObservableFactory detailFactory,
                                       
Object detailKeyType,
                                       
Object detailValueType)

Creates a detail observable map from a master observable value and a factory. This can be used to create observable maps that represent a map property of a selected object in a table.

Parameters:: master - the observable value to track; detailFactory - a factory for createing IObservableMap instances given a current value of the master; detailKeyType - the element type of the detail observable map's key set, typically of type java.lang.Class and can be null; detailValueType - the element type of the detail observable map's values collection, typically of type java.lang.Class and can be null
Returns:: an observable map that, for any current value of the given master value, behaves like the observable map created by the factory for that current value.
Since:: 1.2
