Member Function Documentation

AddXMLNameValueToList()

char ** GDALMDReaderBase::AddXMLNameValueToList ( char ** papszList, const char * pszName, const char * pszValue )

protectedvirtual

AddXMLNameValueToList Execute from ReadXMLToList to add name and value to list.

AddXMLNameValueToList()

One can override this function for special processing input values before add to list.

Parameters

papszList	A list to fill with name=value strings
pszName	A name to add
pszValue	A value to add

Returns

An input list filled with values

FillMetadata()

bool GDALMDReaderBase::FillMetadata ( GDALMultiDomainMetadata * poMDMD )

virtual

Fill provided metadata store class.

Parameters

poMDMD

Metadata store class

Returns

true on success or false

GetAcquisitionTimeFromString()

time_t GDALMDReaderBase::GetAcquisitionTimeFromString ( const char * pszDateTime )

protectedvirtual

Convert string like 2012-02-25T00:25:59.9440000Z to time.

GetAcqisitionTimeFromString()

Parameters

pszDateTime

String to convert

Returns

value in time_t

GetMetadataDomain()

char ** GDALMDReaderBase::GetMetadataDomain ( const char * pszDomain )

virtual

Get specified metadata domain.

GetMetadataItem()

Parameters

pszDomain

The metadata domain to return

Returns

List of metadata items

GetMetadataFiles()

virtual char ** GDALMDReaderBase::GetMetadataFiles ( ) const

pure virtual

Get metadata file names.

The caller become owner of returned list and have to free it via CSLDestroy.

Returns

A file name list

HasRequiredFiles()

virtual bool GDALMDReaderBase::HasRequiredFiles ( ) const

pure virtual

Determine whether the input parameter correspond to the particular provider of remote sensing data completely.

Returns

True if all needed sources files found

LoadMetadata()

void GDALMDReaderBase::LoadMetadata ( )

protectedvirtual

Load metadata to the correspondent IMD, RPB, IMAGERY and DEFAULT domains.

LoadMetadata()

ReadXMLToList()

char ** GDALMDReaderBase::ReadXMLToList ( CPLXMLNode * psNode, char ** papszList, const char * pszName = "" )

protectedvirtual

ReadXMLToList Transform xml to list of NULL terminated name=value strings.

CPLReadXMLToList()

Parameters

psNode	A xml node to process
papszList	A list to fill with name=value strings
pszName	A name of parent node. For root xml node should be empty. If name is not empty, the sibling nodes will not proceed

Returns

An input list filled with values
