Detailed Description

Holds the information regarding a query string input parameter and its validation.

The class is extendable through custom validators (C++ only) and/or by subclassing and overriding the value() method.

Since: QGIS 3.10

Member Enumeration Documentation

◆ Type

enum class QgsServerQueryStringParameter::Type

strong

The Type enum represents the parameter type.

Enumerator
String	Parameter is a string.
Integer	Parameter is an integer.
Double	Parameter is a double.
Boolean	Parameter is a boolean.
List	Parameter is a (comma separated) list of strings, the handler will perform any further required conversion of the list values.

Definition at line 57 of file qgsserverquerystringparameter.h.

Constructor & Destructor Documentation

◆ QgsServerQueryStringParameter()

QgsServerQueryStringParameter::QgsServerQueryStringParameter	(	const QString	name,
		bool	required = false,
		QgsServerQueryStringParameter::Type	type = QgsServerQueryStringParameter::Type::String,
		const QString &	description = QString(),
		const QVariant &	defaultValue = QVariant() )

Constructs a QgsServerQueryStringParameter object.

Parameters

name	parameter name
required
type	the parameter type
description	parameter description
defaultValue	default value, it is ignored if the parameter is required

Member Function Documentation

◆ data()

json QgsServerQueryStringParameter::data ( ) const

Returns the handler information as a JSON object.

Definition at line 109 of file qgsserverquerystringparameter.cpp.

◆ description()

QString QgsServerQueryStringParameter::description ( ) const

Returns parameter description.

Definition at line 134 of file qgsserverquerystringparameter.cpp.

◆ hidden()

bool QgsServerQueryStringParameter::hidden ( ) const

Returns true if the parameter is hidden from the schema.

Hidden params can be useful to implement legacy parameters or parameters that can be accepted without being advertised.

Since: QGIS 3.28

Definition at line 155 of file qgsserverquerystringparameter.cpp.

◆ name()

QString QgsServerQueryStringParameter::name ( ) const

Returns the name of the parameter.

Definition at line 145 of file qgsserverquerystringparameter.cpp.

◆ setCustomValidator()

void QgsServerQueryStringParameter::setCustomValidator ( const customValidator & customValidator )

Sets the custom validation function to customValidator.

Validator function signature is: bool ( const QgsServerApiContext &context, QVariant &value )

Note: a validator can change the value if needed and must return true if the validation passed; not available in Python bindings

Definition at line 104 of file qgsserverquerystringparameter.cpp.

◆ setDescription()

void QgsServerQueryStringParameter::setDescription ( const QString & description )

Sets validator description.

Definition at line 150 of file qgsserverquerystringparameter.cpp.

◆ setHidden()

void QgsServerQueryStringParameter::setHidden ( bool hidden )

Set the parameter's hidden status, parameters are not hidden by default.

Since: QGIS 3.28

Definition at line 160 of file qgsserverquerystringparameter.cpp.

◆ typeName()

QString QgsServerQueryStringParameter::typeName ( const Type type )

static

Returns the name of the type.

Definition at line 139 of file qgsserverquerystringparameter.cpp.

◆ value()

QVariant QgsServerQueryStringParameter::value ( const QgsServerApiContext & context ) const

virtual

Extracts the value from the request context by validating the parameter value and converting it to its proper Type.

If the value is not set and a default was not provided an invalid QVariant is returned.

Validation steps:

required
can convert to proper Type
custom validator (if set - not available in Python bindings)

See also: setCustomValidator() (not available in Python bindings)

Returns: the parameter value or an invalid QVariant if not found (and not required)

Exceptions

QgsServerApiBadRequestError if validation fails
