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.

◆ createFileFilter()

QString QgsProcessingParameterPointCloudLayer::createFileFilter ( ) const

overridevirtual

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

◆ 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.
