Detailed Description

A base class for essential device related settings.

This class acts as a base class for essential device related settings. It only contains features that are available for every device.

Since

1.12.58

Examples

Callback.cs.

Constructor & Destructor Documentation

BasicDeviceSettings() [1/2]

BasicDeviceSettings ( Device device )

inline

Constructs a new mv.impact.acquire.BasicDeviceSettings object.

Parameters

[in]

device

A pointer to a mv.impact.acquire.Device object obtained from a mv.impact.acquire.DeviceManager object.

BasicDeviceSettings() [2/2]

BasicDeviceSettings ( Device device, String settingName )

inline

Constructs a new mv.impact.acquire.BasicDeviceSettings object.

Parameters

[in]	device	A pointer to a mv.impact.acquire.Device object obtained from a mv.impact.acquire.DeviceManager object.
[in]	settingName	The name of the driver internal setting to access with this instance. A list of valid setting names can be obtained by a call to mv.impact.acquire.FunctionInterface.availableSettings, new settings can be created with the function mv.impact.acquire.FunctionInterface.createSetting

Member Function Documentation

getEnumerable< T >()

IEnumerable< T > getEnumerable< T > ( )

inlineinherited

Returns an enumerator of a certain type that iterates through the collection.

This interface will allow to e.g. write code like this:

Info info = new Info(pDev);
foreach (Property c in info.getEnumerable<Property>())
{
  validateProperty(c);
}

See the frameworks documentation about the System.Collections.IEnumerable interface for more information.

Returns

An enumerator that iterates through the collection

GetEnumerator()

IEnumerator< int > GetEnumerator ( )

inlineinherited

Returns an enumerator that iterates through the collection.

See the frameworks documentation about the System.Collections.IEnumerable interface for more information.

Returns

An enumerator that iterates through the collection

restoreDefault()

void restoreDefault ( )

inlineinherited

Restores the default for every component of this collection.

Calling this function will restore the default value for every component belonging to this collection.

Note

The caller must have the right to modify the component. Otherwise an exception will be thrown.

Member Data Documentation

basedOn

readonly PropertyS basedOn = new PropertyS()

A string property (read-only) containing the name of the setting this setting is based on.

Since

1.12.67

imageRequestTimeout_ms

readonly PropertyI imageRequestTimeout_ms = new PropertyI()

An integer property defining the maximum time to wait for an image in ms.

Attention

Since Impact Acquire 2.32.0 the default value for this property has been changed! See Calling 'imageRequestWaitFor' Never Returns / An Application No Longer Terminates After Upgrading To Impact Acquire 2.32.0 Or Greater for details.

When this property is set to 0 the timeout never elapses. If the timeout this property defines elapses the currently processed request will be returned to the user even if no data has been captured so far. The result structure of the request object should be examined in that case. Also this should be considered as an error from the users point of view in which case he should clean up the acquisition queue by calling mv.impact.acquire.FunctionInterface.imageRequestReset. Afterwards the capture loop can be restarted.

Note

It is crucial to understand that this is a timeout PER REQUEST! The timespan taken into account for the measurement starts when the driver begins to capture data into this particular buffer! So when queuing 4 buffers with a timeout of 3000 ms each and no data being transmitted by the device for any reason will cause the last buffer to time out 3000*4 = 12000 ms AFTER the buffer has been queued and the acquisition has been started as the driver will wait for up to 3 seconds for each buffer that is being processed. When the device sends data this timeout does not affect the runtime behaviour at all. No additional delay is introduced by it when everything runs as planned.

Examples

Property Documentation

componentEnumerable

IEnumerable<Component> componentEnumerable

getinherited

Returns an enumerator that iterates through the collection.

This interface will allow to e.g. write code like this:

Info info = new Info(pDev);
foreach (Component c in info.componentEnumerable)
{
  Console.WriteLine("{0}", c.name);
}

See the frameworks documentation about the System.Collections.IEnumerable interface for more information.

Returns

An enumerator that iterates through the collection

componentListEnumerable

IEnumerable<ComponentList> componentListEnumerable

getinherited

Returns an enumerator that iterates through all the mv.impact.acquire.ComponentList elements in the collection.

This interface will allow to e.g. write code like this:

Info info = new Info(pDev);
foreach (ComponentList cl in info.componentListEnumerable)
{
  Console.WriteLine("{0}", cl.name);
}

See the frameworks documentation about the System.Collections.IEnumerable interface for more information.

Returns

An enumerator that iterates through the collection

hObj

int hObj

getinherited

Returns a unique identifier for the component collection referenced by this object.

This handle will always reference an object of type mv.impact.acquire.ComponentList.

Returns

A unique identifier for the component referenced by this object.
