Detailed Description

Note: there is a difference between a NULL string (is_null == true) and an empty string (len == 0).

Constructor & Destructor Documentation

impala_udf::StringVal::StringVal ( uint8_t *  ptr = NULL,
int  len = 0 
)
inline

Construct a StringVal from ptr/len. Note: this does not make a copy of ptr so the buffer must exist as long as this StringVal does.

Definition at line 527 of file udf.h.

References len.

impala_udf::StringVal::StringVal ( const char *  ptr)
inline

Construct a StringVal from NULL-terminated c-string. Note: this does not make a copy of ptr so the underlying string must exist as long as this StringVal does.

Definition at line 534 of file udf.h.

StringVal::StringVal ( FunctionContext *  context,
int  len 
)

Creates a StringVal, allocating a new buffer with 'len'. This should be used to return StringVal objects in UDF/UDAs that need to allocate new string memory.
