Member Function Documentation

const char * GDALMajorObject::GetDescription  )  const [virtual]
 

Fetch object description.

The semantics of the returned description are specific to the derived type. For GDALDatasets it is the dataset name. For GDALRasterBands it is actually a description (if supported) or "".

This method is the same as the C function GDALGetDescription().

Returns:
pointer to internal description string.

char ** GDALMajorObject::GetMetadata const char *  pszDomain = ""  )  [virtual]
 

Fetch metadata.

The returned string list is owned by the object, and may change at any time. It is formated as a "Name=value" list with the last pointer value being NULL. Use the the CPL StringList functions such as CSLFetchNameValue() to manipulate it.

Note that relatively few formats return any metadata at this time.

This method does the same thing as the C function GDALGetMetadata().

Parameters:
pszDomain the domain of interest. Use "" or NULL for the default domain.
Returns:
NULL or a string list.

const char * GDALMajorObject::GetMetadataItem const char *  pszName,
const char *  pszDomain = ""
[virtual]
 

Fetch single metadata item.

The C function GDALGetMetadataItem() does the same thing as this method.

Parameters:
pszName the key for the metadata item to fetch.
pszDomain the domain to fetch for, use NULL for the default domain.
Returns:
NULL on failure to find the key, or a pointer to an internal copy of the value string on success.

void GDALMajorObject::SetDescription const char *  pszNewDesc  )  [virtual]
 

Set object description.

The semantics of the description are specific to the derived type. For GDALDatasets it is the dataset name. For GDALRasterBands it is actually a description (if supported) or "".

Normally application code should not set the "description" for GDALDatasets. It is handled internally.

This method is the same as the C function GDALSetDescription().

CPLErr GDALMajorObject::SetMetadata char **  papszMetadataIn,
const char *  pszDomain = ""
[virtual]
 

Set metadata.

The C function GDALSetMetadata() does the same thing as this method.

Parameters:
papszMetadata the metadata in name=value string list format to apply.
pszDomain the domain of interest. Use "" or NULL for the default domain.
Returns:
CE_None on success, CE_Failure on failure and CE_Warning if the metadata has been accepted, but is likely not maintained persistently by the underlying object between sessions.

CPLErr GDALMajorObject::SetMetadataItem const char *  pszName,
const char *  pszValue,
const char *  pszDomain = ""
[virtual]
 

Set single metadata item.

The C function GDALSetMetadataItem() does the same thing as this method.

Parameters:
pszName the key for the metadata item to fetch.
pszValue the value to assign to the key.
pszDomain the domain to set within, use NULL for the default domain.
Returns:
CE_None on success, or an error code on failure.
