Oracle BRM: Data types
Here's a detailed explanation of the data types specifically mentioned for Oracle BRM, along with examples for each:
1. pcm_context_t
Description: Represents a context for communication between the client application and BRM server.
Example:
pcm_context_t *ctxp = NULL;
PCM_CONNECT(&ctxp, &ebuf);
2. pin_errbuf_t
Description: Used for error handling; contains error status and description.
Example:
pin_errbuf_t ebuf;
PIN_ERRBUF_CLEAR(&ebuf);
3. poid_t
Description: Represents a pointer to an object ID in the BRM database.
Example:
poid_t *account_poid = PCM_GET_USERID(ctxp);
4. pin_flist_t
Description: A flexible list that represents data structures in BRM.
Example:
pin_flist_t *flistp = PIN_FLIST_CREATE(&ebuf);
5. pin_cookie_t
Description: Used with arrays in FLISTs to iterate through elements.
Example:
pin_cookie_t cookie = NULL;
pin_flist_t *sub_flist = PIN_FLIST_ELEM_GET_NEXT(flistp, PIN_FLD_SUB_BAL_IMPACTS, &rec_id, 1, &cookie, &ebuf);
6. time_t
Description: Represents time in seconds since the Epoch (00:00:00 UTC, January 1, 1970).
Example:
time_t current_time;
time(¤t_time);
7. cm_cache_key_poid_t
Description: Used for caching mechanisms in custom applications using POID as a key.
Example: Typically used internally in custom cache implementations and may not directly appear in API usage.
8. cm_cache_key_iddbstr_t
Description: Represents a cache key consisting of an ID and a database string, used in custom caching.
Example: Specific to caching implementations and might be used in defining cache structures for performance optimizations.
9. cm_nap_connection_t
Description: Represents a Network Access Point (NAP) connection in BRM for session management.
Example: More internal to the BRM engine, handling connections to the BRM server.
10. pin_fld_num_t
Description: Represents numeric field numbers in BRM, typically used for indexing fields in FLISTs.
Example:
pin_fld_num_t fld_num = PIN_FLD_ACCOUNT_NO;
11. pin_decimal_t
Description: Used for decimal numbers in BRM, to handle precision numbers like currency.
Example:
pin_decimal_t *amount = pbo_decimal_from_str("123.45", &ebuf);
12. pin_buf_t
Description: Used to handle binary or string buffer fields in BRM FLISTs.
Example:
pin_buf_t *buf;
buf->data = "Sample data";
buf->size = strlen(buf->data);
13. caddr_t
Description: A type definition for a character address; it's a generic pointer to a character or byte.
Example:
caddr_t addr = (caddr_t)malloc(100);
14. pin_binstr_t
Description: Represents a binary string in BRM.
Example: Used for binary data fields, similar to `pin_buf_t` but specific to binary strings.
15. int32, enum
Description: `int32` is a 32-bit integer, and `enum` is used for enumerated types.
Example:
int32 num = 10;
enum {RED, GREEN, BLUE} color;
color = RED;
16. char * (UTF8 encoding)
Description: A pointer to a character array, used for strings with UTF-8 encoding.
Example:
char *name = "John Doe";
These examples demonstrate how each data type is utilized in the context of Oracle BRM applications, providing a foundation for both data manipulation and system interaction within the BRM ecosystem.
