Constructor & Destructor Documentation

◆ QgsFilterResponseDecorator()

QgsFilterResponseDecorator::QgsFilterResponseDecorator	(	QgsServerFiltersMap	filters,
		QgsServerResponse &	response )

Constructor for QgsFilterResponseDecorator.

filters	Map of filters to apply before terminating the response
response	Server response

Definition at line 23 of file qgsfilterresponsedecorator.cpp.

Member Function Documentation

◆ addHeader()

void QgsFilterResponseDecorator::addHeader	(	const QString &	key,
		const QString &	value )

inlineoverridevirtual

Add a header value for the given key, without replacing any existing value for the same key Add Header entry to the response.

Note: that it is usually an error to set Header after data have been sent through the wire

See also: setHeader() for a method that replaces any existing value(s) for the same header key

Since: QGIS 4.2

Implements QgsServerResponse.

Definition at line 59 of file qgsfilterresponsedecorator.h.

◆ clear()

void QgsFilterResponseDecorator::clear ( )

inlineoverridevirtual

Reset all headers and content for this response.

Implements QgsServerResponse.

Definition at line 95 of file qgsfilterresponsedecorator.h.

◆ data()

QByteArray QgsFilterResponseDecorator::data ( ) const

inlineoverridevirtual

Gets the data written so far.

This is implementation dependent: some implementations may not give access to the underlying and return an empty array.

Note that each call to 'flush' may empty the buffer and in case of streaming process you may get partial content

Implements QgsServerResponse.

Definition at line 97 of file qgsfilterresponsedecorator.h.

◆ feedback()

QgsFeedback * QgsFilterResponseDecorator::feedback ( ) const

inlineoverridevirtual

Returns the socket feedback if any.

Since: QGIS 3.36

Reimplemented from QgsServerResponse.

Definition at line 101 of file qgsfilterresponsedecorator.h.

◆ finish()

void QgsFilterResponseDecorator::finish ( )

overridevirtual

Finish the response, ending the transaction.

The default implementation does nothing.

Reimplemented from QgsServerResponse.

Definition at line 54 of file qgsfilterresponsedecorator.cpp.

◆ flush()

void QgsFilterResponseDecorator::flush ( )

overridevirtual

Flushes the current output buffer to the network.

'flush()' may be called multiple times. For HTTP transactions headers will be written on the first call to 'flush()'. The default implementation does nothing.

Reimplemented from QgsServerResponse.

Definition at line 71 of file qgsfilterresponsedecorator.cpp.

◆ fullHeader()

virtual QList< QString > QgsFilterResponseDecorator::fullHeader ( const QString & key ) const

inlineoverridevirtual

Returns a (possibly empty) list of all the header values for the given key.

See also: header() to get only the last value for a given header key

Since: QGIS 4.2

Implements QgsServerResponse.

Definition at line 77 of file qgsfilterresponsedecorator.h.

◆ fullHeaders()

virtual QMap< QString, QList< QString > > QgsFilterResponseDecorator::fullHeaders ( ) const

inlineoverridevirtual

Returns all the header values.

See also: headers() to get only the last value for each header key

Since: QGIS 4.2

Implements QgsServerResponse.

Definition at line 79 of file qgsfilterresponsedecorator.h.

◆ header()

Q_DECL_DEPRECATED QString QgsFilterResponseDecorator::header ( const QString & key ) const

inlineoverridevirtual

Returns a single header value for a given key.

Note: if multiple values are set for the same key, the last one is returned

Deprecated: QGIS 4.2. Use fullHeader() instead.

Implements QgsServerResponse.

Definition at line 63 of file qgsfilterresponsedecorator.h.

◆ headers()

Q_DECL_DEPRECATED QMap< QString, QString > QgsFilterResponseDecorator::headers ( ) const

inlineoverridevirtual

Returns the header values as a map: only the last value is returned if multiple values are set for the same header.

See also: fullHeaders() to get all the values for all the headers

Deprecated: QGIS 4.2. Use fullHeaders() instead.

Implements QgsServerResponse.

Definition at line 70 of file qgsfilterresponsedecorator.h.

◆ headersSent()

bool QgsFilterResponseDecorator::headersSent ( ) const

inlineoverridevirtual

Returns true if the headers have already been sent.

Implements QgsServerResponse.

Definition at line 81 of file qgsfilterresponsedecorator.h.

◆ io()

QIODevice * QgsFilterResponseDecorator::io ( )

inlineoverridevirtual

Returns the underlying QIODevice.

Implements QgsServerResponse.

Definition at line 89 of file qgsfilterresponsedecorator.h.

◆ ready()

void QgsFilterResponseDecorator::ready ( )

Call filters projectReady() method.

Since: QGIS 3.36

Definition at line 41 of file qgsfilterresponsedecorator.cpp.

◆ removeHeader()

void QgsFilterResponseDecorator::removeHeader ( const QString & key )

inlineoverridevirtual

Clear all header values for the given key Undo a previous 'setHeader' call.

Implements QgsServerResponse.

Definition at line 61 of file qgsfilterresponsedecorator.h.

◆ sendError()

void QgsFilterResponseDecorator::sendError	(	int	code,
		const QString &	message )

inlineoverridevirtual

Send error This method delegates error handling at the server level.

This is different from calling setReturnCode() which let you return a specific response body. Calling sendError() will end the transaction and any attempt to write data or set headers will be an error.

Parameters

code	HHTP return code value
message	An informative error message

Implements QgsServerResponse.

Definition at line 87 of file qgsfilterresponsedecorator.h.

◆ setHeader()

void QgsFilterResponseDecorator::setHeader	(	const QString &	key,
		const QString &	value )

inlineoverridevirtual

Set a single header value replacing any existing value(s) for the same key.

Note: that it is usually an error to set Header after data have been sent through the wire

See also: addHeader() for a method that allows setting multiple values for the same header key; removeHeader() to clear header values for a given key

Implements QgsServerResponse.

Definition at line 57 of file qgsfilterresponsedecorator.h.

◆ setStatusCode()

void QgsFilterResponseDecorator::setStatusCode ( int code )

inlineoverridevirtual

Set the http status code.

Parameters

code	HTTP status code value

Implements QgsServerResponse.

Definition at line 83 of file qgsfilterresponsedecorator.h.

◆ start()

void QgsFilterResponseDecorator::start ( )

Call filters requestReady() method.

Definition at line 28 of file qgsfilterresponsedecorator.cpp.

◆ statusCode()

int QgsFilterResponseDecorator::statusCode ( ) const

inlineoverridevirtual

Returns the http status code.

Implements QgsServerResponse.

Definition at line 85 of file qgsfilterresponsedecorator.h.

◆ truncate()

void QgsFilterResponseDecorator::truncate ( )

inlineoverridevirtual

Truncate data.

Clear internal buffer

Implements QgsServerResponse.

Definition at line 99 of file qgsfilterresponsedecorator.h.
