This class represents a style manager
| OGRStyleMgr::OGRStyleMgr | ( | OGRStyleTable * | poDataSetStyleTable = NULL | ) |
Constructor.
This method is the same as the C function OGR_SM_Create()
| poDataSetStyleTable | (currently unused, reserved for future use), pointer to OGRStyleTable. Pass NULL for now. |
Destructor.
This method is the same as the C function OGR_SM_Destroy()
| GBool OGRStyleMgr::AddPart | ( | OGRStyleTool * | poStyleTool | ) |
Add a part (style tool) to the current style.
This method is the same as the C function OGR_SM_AddPart().
| poStyleTool | the style tool defining the part to add. |
| GBool OGRStyleMgr::AddPart | ( | const char * | pszPart | ) |
Add a part (style string) to the current style.
| pszPart | the style string defining the part to add. |
| GBool OGRStyleMgr::AddStyle | ( | const char * | pszStyleName, |
| const char * | pszStyleString = NULL |
||
| ) |
Add a style to the current style table.
This method is the same as the C function OGR_SM_AddStyle().
| pszStyleName | the name of the style to add. |
| pszStyleString | the style string to use, or NULL to use the style stored in the manager. |
References OGRStyleTable::AddStyle().
| OGRStyleTool * OGRStyleMgr::GetPart | ( | int | nPartId, |
| const char * | pszStyleString = NULL |
||
| ) |
Fetch a part (style tool) from the current style.
This method is the same as the C function OGR_SM_GetPart().
This method instanciates a new object that should be freed with OGR_ST_Destroy().
| nPartId | the part number (0-based index). |
| pszStyleString | (optional) the style string on which to operate. If NULL then the current style string stored in the style manager is used. |
| int OGRStyleMgr::GetPartCount | ( | const char * | pszStyleString = NULL | ) |
Get the number of parts in a style.
This method is the same as the C function OGR_SM_GetPartCount().
| pszStyleString | (optional) the style string on which to operate. If NULL then the current style string stored in the style manager is used. |
| const char * OGRStyleMgr::GetStyleByName | ( | const char * | pszStyleName | ) |
find a style in the current style table.
| pszStyleName | the name of the style to add. |

| const char * OGRStyleMgr::GetStyleName | ( | const char * | pszStyleString = NULL | ) |
Get the name of a style from the style table.
| pszStyleString | the style to search for, or NULL to use the style currently stored in the manager. |

Get the style string from the style manager.
| poFeature | feature object from which to read the style or NULL to get the style string stored in the manager. |
NOTE: this method will call OGRStyleMgr::InitFromFeature() if poFeature is not NULL and replace the style string stored in the style manager
References InitFromFeature().
| const char * OGRStyleMgr::InitFromFeature | ( | OGRFeature * | poFeature | ) |
