Naming Conventions

abap-util follows a small set of conventions that make the API easy to navigate from code completion alone.

Object Names

Pattern	Used for	Example
zabaputil_cl_*	Classes	zabaputil_cl_util_log
zabaputil_cx_*	Exception classes	zabaputil_cx_util_error
zabaputil_if_*	Interfaces (vendored)	zabaputil_if_ajson_filter
zabaputil_t_*	Database tables	zabaputil_t_91

The zabaputil_ prefix is reserved — never create your own objects under it.

Method Prefixes

The façade zabaputil_cl_util groups helpers by topic. The prefix tells you what the method does without reading the body:

Prefix	Meaning	Example
c_	Character / string operation	c_trim, c_split, c_contains
time_	Time / date arithmetic	time_add_seconds
rtti_	Run-time type info	rtti_get_type_name
json_	JSON	json_stringify
xml_	XML (asXML / S-RTTI)	xml_stringify, xml_srtti_parse
conv_	Conversion / encoding	conv_encode_x_base64
filter_	Filter / token / range	filter_get_sql_where
itab_	Internal tables	itab_corresponding
msg_	Message extraction	msg_get, msg_get_t
boolean_	Boolean checks	boolean_check_by_data
url_param_	URL query handling	url_param_get
x_	Exception helpers	x_check_raise, x_raise
ui5_	UI5 helpers	ui5_get_msg_type
context_	Runtime context	context_get_user_tech
source_	Source code introspection	source_get_method
app_	App URL helpers	app_get_url
uuid_	UUID generation	uuid_get_c32

Verb Conventions

Verb fragment	Meaning
get_*	Pure getter — never raises, no side effects
check_*	Returns abap_bool
set_*	Mutates state (instance method)
add_*	Appends to internal state (e.g. log entries)
*_by_*	Conversion: _x_by_y reads as "build x from y"
to_*	Renders the current state to a target format (to_csv, to_xlsx)

For example itab_get_csv_by_itab( val ) reads as "get a CSV from an internal table".

Parameter Names

The library deliberately keeps parameter names short so calls fit on one line:

Parameter	Meaning
val	The primary input value
result	The returning value
data	Generic, typed by TYPE any
tab	Internal table
t_*	Standard table of *
s_*	Structure of *
n / v	Name / value pair
ns	XML namespace
when	Boolean condition

If you find a method whose parameter is not val, that's intentional — it usually means the method has more than one input and the names disambiguate roles (e.g. low/high, from/to).
