ABAP Range utility
For many years, I was annoyed by the cumbersome handling of ABAP ranges. There were countless attempts to program a tool to simplify their use.
This repository is the result of my efforts. It essentially consists of the class ZCL_RANGE.
Main usage
existing_range = corresponding #( zcl_range=>init( )->equals( 'A' )->get( ) ).
Note that you need to convert to your range using corresponding #(. After that, you have a line with SIGN = 'I', OPTION = 'EQ' and low = 'A' in your range.
There are further base methods: greater( ), less( ), between( )
Working with patterns
Patterns ('CP') are recognized automatically by the existence of wild cards and can be used with the equals( ) call.
Using existing lines
existing_range = corresponding #( zcl_range=>init( existing_range )->equuals( 'A' )->get( ) ).
When you pass an existing range, the new entries will be added.
Working with qualifiers
rng = corresponding #( zcl_range=>init( )->exclude( )->equals( 'A' )->get( ) ).
Note that this sets the SIGN to 'E' for all following actions, until include( ) is called.
rng = corresponding #( zcl_range=>init( )->not( )->equals( 'B' )->get( ) ).
This creates a 'NE' entry. The NOT qualifyer only affects the next call.
rng = corresponding #( zcl_range=>init( )->and_equal( )->greater( 'B' )->get( ) ).
With this, you can create a 'GE' entry. Just as NOT, it affects only the following call.
Making multiple entries
tab = value #( ( 'A' ) ( 'B' ) ( 'C' ) ).
rng = corresponding #( zcl_range=>init( )->equals( tab )->get( ) ).
EQUALS can take a table as parameter. It should be either without structure or with a compatible first component, which is being used then. You will get
one EQ entry for each line.
Demo report
See ZP_RANGES_DEMO for some examples.
rng = corresponding #( zcl_range=>init( )->from_list( 'A|B|C' )->get( ) ).
This shortcut creates multiple 'EQ' entries, using the pipe as separator
Supported types
The range can be of character types, type D, type T, type P and type I. ABAPs intrinsinc type conversion makes sure that everything is being converted correctly.
