Member Function Documentation

void kanzi::BindingSourceRuntime::attachForRead ( )

Attaches the binding source runtime for reading.

After attaching the binding source runtime for reading, the binding source triggers calls to AbstractBindingRuntime::notifySourceChanged(). Calling this function on binding sources is optional. Most bindings need source write notifications, and the binding runtime calls this function. You must call attachForWrite() before calling this function.

void kanzi::BindingSourceRuntime::attachForWrite ( )

Attaches the binding source runtime for writing.

After this function is called and the target is connected, you can call the write() function to write the values to the source. You must call this function before calling attachForRead().

void kanzi::BindingSourceRuntime::detach ( )

Detaches the binding source runtime.

bool kanzi::BindingSourceRuntime::read ( Variant value)

Reads a value from binding source.

Parameters
valueOutput parameter for value read.
Returns
Write success status.
bool kanzi::BindingSourceRuntime::write ( const Variant value)

Writes a value to binding source.

Parameters
valueValue to write.
Returns
Write success status.
bool kanzi::BindingSourceRuntime::isConnected ( )

Indicates whether this source is connected.

Returns
If the source is connected, true, otherwise false.
void kanzi::BindingSourceRuntime::createBindingProcessorRuntimes ( const AbstractBinding binding)

Creates a processor runtime for each BindingProcessor held by the binding parameter.

Parameters
bindingThe binding containing a collection of processors.
BindingProcessorRuntimeConstIterator kanzi::BindingSourceRuntime::beginProcessorRuntimes ( ) const
inline

Gets an iterator to the beginning of binding processors.

Returns
Iterator to beginning of processor array.
BindingProcessorRuntimeConstIterator kanzi::BindingSourceRuntime::endProcessorRuntimes ( ) const
inline

Gets an iterator to the end of binding processors.

Returns
Iterator to end of processor array.
BindingLookupContext& kanzi::BindingSourceRuntime::getLookupContext ( ) const
inline

Gets the lookup context.

Returns
The binding lookup context.
void kanzi::BindingSourceRuntime::setBindingRuntime ( AbstractBindingRuntime bindingRuntime)
inline

Sets the binding runtime.

This function is called during construction, after setting the source runtime to the binding runtime.

Parameters
bindingRuntimeBinding runtime to set.
AbstractBindingRuntime* kanzi::BindingSourceRuntime::getBindingRuntime ( ) const
inline

Gets the binding runtime.

Returns
Pointer to owning binding runtime.
