## Detailed Description

A Key Value pair.

This object contains a 'key' string and one or more 'value' strings. Typically key value pairs are specified in map files (using the <key> tag). They allow a game developer to tag game specific information to any Crystal Space object.

Main creators of instances implementing this interface:

- The main loader creates instances of this internally.

Main ways to get pointers to this interface:

- scfQueryInterface() from iObject instances you get by calling iObject::GetIterator() on iObject instances you get from CS objects (typically using QueryObject()).

## Member Function Documentation

virtual const char* iKeyValuePair::GetKey | ( |  | ) | const`[pure virtual]`

| Get the key string of the pair. Implemented in csKeyValuePair.

virtual const char* iKeyValuePair::GetValue | ( |  | ) | const`[pure virtual]`

| Get the 'value' string of the pair. This is the same as calling 'GetValue ("value")'. Implemented in csKeyValuePair.

virtual const char* iKeyValuePair::GetValue | ( | const char * | vname | ) | const`[pure virtual]`

| Get a value string from the pair. Implemented in csKeyValuePair.

virtual csRef<iStringArray> iKeyValuePair::GetValueNames | ( |  | ) | const`[pure virtual]`

| Get a list of the names of values in the pair. Implemented in csKeyValuePair.

virtual iObject* iKeyValuePair::QueryObject | ( |  | ) | `[pure virtual]`

| Get the iObject. Implemented in csKeyValuePair.

virtual void iKeyValuePair::SetKey | ( | const char * | key | ) | `[pure virtual]`

| Set the key string of the pair. Implemented in csKeyValuePair.

virtual void iKeyValuePair::SetValue | ( | const char * | value | ) | `[pure virtual]`

| Set the value string of the pair. This is the same as calling 'SetValue ("value", value)'. Implemented in csKeyValuePair.

virtual void iKeyValuePair::SetValue | ( | const char * | vname,
|  | const char * | value
| ) | `[pure virtual]`

| Set a value string of the pair. Implemented in csKeyValuePair.
