Constructor & Destructor Documentation

◆ QgsProcessingParameterPointCloudLayer()

QgsProcessingParameterPointCloudLayer::QgsProcessingParameterPointCloudLayer ( const QString &  name,
const QString &  description = QString(),
const QVariant &  defaultValue = QVariant(),
bool  optional = false 
)

Member Function Documentation

◆ checkValueIsAcceptable()

bool QgsProcessingParameterPointCloudLayer::checkValueIsAcceptable ( const QVariant &  input,
QgsProcessingContext context = nullptr 
) const
overridevirtual

Checks whether the specified input value is acceptable for the parameter.

Returns true if the value can be accepted. The optional context parameter can be specified to allow a more stringent check to be performed, capable of checking for the presence of required layers and other factors within the context.

Reimplemented from QgsProcessingParameterDefinition.

Definition at line 9221 of file qgsprocessingparameters.cpp.

◆ clone()

QgsProcessingParameterDefinition * QgsProcessingParameterPointCloudLayer::clone ( ) const
overridevirtual

Creates a clone of the parameter definition.

Implements QgsProcessingParameterDefinition.

Definition at line 9216 of file qgsprocessingparameters.cpp.

◆ createFileFilter()

QString QgsProcessingParameterPointCloudLayer::createFileFilter ( ) const
overridevirtual

This method needs to be reimplemented in all classes which implement this interface and return a file filter.

Implements QgsFileFilterGenerator.

Definition at line 9290 of file qgsprocessingparameters.cpp.

◆ fromScriptCode()

QgsProcessingParameterPointCloudLayer * QgsProcessingParameterPointCloudLayer::fromScriptCode ( const QString &  name,
const QString &  description,
bool  isOptional,
const QString &  definition 
)
static

Creates a new parameter using the definition from a script code.

Definition at line 9295 of file qgsprocessingparameters.cpp.

◆ type()

QString QgsProcessingParameterPointCloudLayer::type ( ) const
inlineoverridevirtual

Unique parameter type name.

Implements QgsProcessingParameterDefinition.

◆ typeName()

static QString QgsProcessingParameterPointCloudLayer::typeName ( )
inlinestatic

Returns the type name for the parameter class.

◆ valueAsJsonObject()

QVariant QgsProcessingParameterPointCloudLayer::valueAsJsonObject ( const QVariant &  value,
QgsProcessingContext context 
) const
overridevirtual

Returns a version of the parameter input value, which is suitable for use in a JSON object.

This method must return only simple values which can be losslessly encapsulated in a serialized JSON map. For instance, any QGIS class values (such as QgsCoordinateReferenceSystem) must be converted to a simple string or numeric value equivalent.
