Constructor Detail

JavaLong

public JavaLong(Accessor parent,
                LongBinding binding,
                java.lang.Object object,
                AccessorParams params)
Method Detail

getBinding

public LongBinding getBinding()
Overrides:
getBinding in class JavaObject

type

public LongType type()
Description copied from interface: Accessor
Get structural represtentation of the accessor presented in databoard's type system.

Specified by:
type in interface Accessor
Specified by:
type in interface LongAccessor
Overrides:
type in class JavaObject
Returns:
type description

getValue

public long getValue()
              throws AccessorException
Specified by:
getValue in interface LongAccessor
Throws:
AccessorException

setValue

public void setValue(long newValue)
              throws AccessorException
Specified by:
setValue in interface LongAccessor
Throws:
AccessorException

setValue

public void setValue(Binding binding,
                     java.lang.Object newValue)
              throws AccessorException
Description copied from interface: Accessor
Set a complete new value to the data container. If the new value removes old map entries, array entries, optional value, or changes union or variant value type, it will disengage any existing sub-accessors and send InvalidatedEvent.

Writing the current value again may not emit an event. This is implementation specific.

Write is durable, once a the method returns successfully the value has been stored in the implmentation.

Specified by:
setValue in interface Accessor
Throws:
AccessorException

getComponent

public <T extends Accessor> T getComponent(ChildReference reference)
                                throws AccessorConstructionException
Description copied from interface: Accessor
Open an accessor to a child. If one already exists, the existing is returned, otherwise a new is created. Child accessors are often remembered with weak reference.

InvalidatedEvent is thrown from the accessor if it is unlinked from the parent hierarchy.

Specified by:
getComponent in interface Accessor
Parameters:
reference - component reference path or null to return _this_ accessor
Returns:
accessor
Throws:
AccessorConstructionException
