Member Function Documentation

autoCreated()

bool QgsProcessingOutputDefinition::autoCreated ( ) const

inline

Returns true if the output was automatically created when adding a parameter.

setAutoCreated()

Since

QGIS 3.14

Definition at line 134 of file qgsprocessingoutputs.h.

description()

QString QgsProcessingOutputDefinition::description ( ) const

inline

Returns the description for the output.

This is the user-visible string used to identify this output.

setDescription()

Definition at line 112 of file qgsprocessingoutputs.h.

name()

QString QgsProcessingOutputDefinition::name ( ) const

inline

Returns the name of the output.

This is the internal identifier by which algorithms access this output.

setName()

Definition at line 98 of file qgsprocessingoutputs.h.

setAutoCreated()

void QgsProcessingOutputDefinition::setAutoCreated ( bool  autoCreated )

inline

Sets whether an output was automatically created when adding a parameter.

Parameters

autoCreated

set to true if the output is to be considered as automatically created.

setDescription()

void QgsProcessingOutputDefinition::setDescription ( const QString &  description )

inline

Sets the description for the output.

This is the user-visible string used to identify this output.

See also

description()

Definition at line 119 of file qgsprocessingoutputs.h.

setName()

void QgsProcessingOutputDefinition::setName ( const QString &  name )

inline

Sets the name of the output.

This is the internal identifier by which algorithms access this output.

name()

Definition at line 105 of file qgsprocessingoutputs.h.

type()

virtual QString QgsProcessingOutputDefinition::type ( ) const

pure virtual

Unique output type name.

Implemented in QgsProcessingOutputMapLayer, QgsProcessingOutputVectorLayer, QgsProcessingOutputRasterLayer, QgsProcessingOutputPointCloudLayer, QgsProcessingOutputMultipleLayers, QgsProcessingOutputHtml, QgsProcessingOutputVariant, QgsProcessingOutputNumber, QgsProcessingOutputString, QgsProcessingOutputBoolean, QgsProcessingOutputFolder, QgsProcessingOutputFile, QgsProcessingOutputConditionalBranch, and QgsProcessingOutputVectorTileLayer.

valueAsFormattedString()

QString QgsProcessingOutputDefinition::valueAsFormattedString ( const QVariant &  value, QgsProcessingContext &  context, bool &  ok  ) const

virtual

Returns a HTML string version of the parameter output value (if possible).

By default this will return the same value as valueAsString().

Parameters

value	value to convert
context	processing context
ok	will be set to true if value could be represented as a string.

Returns

value converted to string

See also

valueAsString()

Since

QGIS 3.36

Reimplemented in QgsProcessingOutputHtml, QgsProcessingOutputFolder, and QgsProcessingOutputFile.

Definition at line 46 of file qgsprocessingoutputs.cpp.

valueAsString()

QString QgsProcessingOutputDefinition::valueAsString ( const QVariant &  value, QgsProcessingContext &  context, bool &  ok  ) const

virtual

Returns a string version of the parameter output value (if possible).

Parameters

value	value to convert
context	processing context
ok	will be set to true if value could be represented as a string.

Returns

value converted to string

See also

valueAsFormattedString()

Since

QGIS 3.36
