## Description

This interface is used to define a symbol, normally got from symbol queries. A symbol has various fields that can be retrieved by using their get methods. A symbol will have only those fields which have been selected to be included in their respective queries, so make sure the needed fields are correctly specified during query creation.

    	IANJUTA_SYMBOL_FIELD_FILE_POS,
    	IANJUTA_SYMBOL_FILED_SCOPE_DEF_ID,

Symbol Fields. Used to define and retrieve results from query. Each of these fields are either integer or string. Use the right method to retrieve them. That is, for integer use `ianjuta_symbol_get_int()`, for string use `ianjuta_symbol_get_string()`, and for boolean use `ianjuta_symbol_get_boolean()`. Some fields can be in both forms, e.g. IANJUTA_SYMBOL_FIELD_TYPE.

`IANJUTA_SYMBOL_FIELD_ID` | Integer. A unique ID of the symbol
`IANJUTA_SYMBOL_FIELD_NAME` | String. Name of the symbol
`IANJUTA_SYMBOL_FIELD_FILE_POS` | Integer. The file line number where the symbol is found.
`IANJUTA_SYMBOL_FILED_SCOPE_DEF_ID` |
`IANJUTA_SYMBOL_FIELD_FILE_SCOPE` | Boolean: TRUE if symbol is within file scope, otherwise FALSE.
`IANJUTA_SYMBOL_FIELD_SIGNATURE` | String. Signature of a method, if symbol is a funtion. Namely, the arguments list of the funtion.
`IANJUTA_SYMBOL_FIELD_RETURNTYPE` | String. Return type of a method, if symbol is a function.
`IANJUTA_SYMBOL_FIELD_TYPE` | Both string and Integer. Type attribute of a symbol. In string form, it is name of the type in string form. In integer form, it is IAnjutaSymbolType enumerator value.
`IANJUTA_SYMBOL_FIELD_TYPE_NAME` | type_name attribute of a symbol. If a type could be "class" then its type_name may be "MyFooClass" etc.
`IANJUTA_SYMBOL_FIELD_FILE_PATH` | String. The relative path to the file where the symbol is found.
`IANJUTA_SYMBOL_FIELD_PROJECT_NAME` | String. The project name to which the symbol belongs to.
`IANJUTA_SYMBOL_FIELD_PROJECT_VERSION` | String. The project version to which the symbol belongs to.
`IANJUTA_SYMBOL_FIELD_IMPLEMENTATION` | String. Implementation attribute of a symbol. It may be "pure virtual", "virtual", etc.
`IANJUTA_SYMBOL_FIELD_ACCESS` | String. Access attribute of a symbol. It may be "public", "private" etc.
`IANJUTA_SYMBOL_FIELD_KIND` | Kind attribute of a symbol, such as "enumerator", "namespace", "class" etc.
`IANJUTA_SYMBOL_FIELD_IS_CONTAINER` | Boolean. TRUE if symbol is a scope container, such as namespace, class, struct etc., otherwise FALSE.
`IANJUTA_SYMBOL_FIELD_END` | The end marker.
