Member Function Documentation

attachForRead()

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.

attachForWrite()

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().

detach()

void kanzi::BindingSourceRuntime::detach

(

)

Detaches the binding source runtime.

read()

bool kanzi::BindingSourceRuntime::read

(

Variant &

value

)

Reads a value from binding source.

Parameters

value

Output parameter for value read.

Returns

Write success status.

write()

bool kanzi::BindingSourceRuntime::write

(

const Variant &

value

)

Writes a value to binding source.

Parameters

value

Value to write.

Returns

Write success status.

isConnected()

bool kanzi::BindingSourceRuntime::isConnected

(

)

Indicates whether this source is connected.

Returns

If the source is connected, true, otherwise false.

createBindingProcessorRuntimes()

void kanzi::BindingSourceRuntime::createBindingProcessorRuntimes

(

const AbstractBinding &

binding

)

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

Parameters

binding

The binding containing a collection of processors.

beginProcessorRuntimes()

BindingProcessorRuntimeConstIterator kanzi::BindingSourceRuntime::beginProcessorRuntimes ( ) const

inline

Gets an iterator to the beginning of binding processors.

Returns

Iterator to beginning of processor array.

endProcessorRuntimes()

BindingProcessorRuntimeConstIterator kanzi::BindingSourceRuntime::endProcessorRuntimes ( ) const

inline

Gets an iterator to the end of binding processors.

Returns

Iterator to end of processor array.

getLookupContext()

BindingLookupContext & kanzi::BindingSourceRuntime::getLookupContext ( ) const

inline

Gets the lookup context.

Returns

The binding lookup context.

setBindingRuntime()

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

bindingRuntime

Binding runtime to set.

getBindingRuntime()

AbstractBindingRuntime * kanzi::BindingSourceRuntime::getBindingRuntime ( ) const

inline

Gets the binding runtime.

Returns

Pointer to owning binding runtime.
