Detailed Description

This object describes a HyperText Transport Protocol resource which is a string kept in memory.

For instance a pre-calculated HTML string could be set in this type of resource.

Constructor & Destructor Documentation

PHTTPString::PHTTPString ( const PURL & url )

Contruct a new simple string resource for the HTTP space.

	)

Member Function Documentation

const PString& PHTTPString::GetString ( )

inline

Get the string for this resource.

Returns: String for resource.

References m_string.

virtual PBoolean PHTTPString::LoadHeaders ( PHTTPRequest & request )

virtual

Get the headers for block of data (eg HTML) that the resource contains.

This will fill in all the fields of the outMIME parameter required by the resource and return the status for the load.

Returns: true if all OK, false if an error occurred.

Reimplemented from PHTTPResource.

virtual PString PHTTPString::LoadText ( PHTTPRequest & request )

virtual

Get a block of text data (eg HTML) that the resource contains.

The default behaviour is to assert, one of LoadText() or LoadData() functions must be overridden for correct operation.

Returns: String for loaded text.

Reimplemented from PHTTPResource.

Reimplemented in PHTTPServiceProcess::ClearLogPage, PServiceHTTPString, and PRegisterPage.

void PHTTPString::SetString ( const PString & str )

inline

Set the string to be returned by this resource.

References m_string.
