Class AbapPreprocessor

java.lang.Object

eu.cqse.check.framework.preprocessor.abap.AbapPreprocessor

All Implemented Interfaces:

IPreprocessor

public class AbapPreprocessor
extends java.lang.Object
implements IPreprocessor

Preprocessor for ABAP. It rolls out so-called "chain sentences" in order to make parsing easier. For example, the following two code snippets are equivalent:

• DATA: a TYPE i, b TYPE x.
• DATA a TYPE i. DATA b TYPE x.

Basically, whenever there is a colon, this means that every statement after a comma begins with whatever came before the colon.

Method Detail

preprocess

public java.util.List<IToken> preprocess(java.lang.String uniformPath,
                                         java.util.List<IToken> tokens)

Performs the actual preprocessing of the given tokens.

Specified by:

preprocess in interface IPreprocessor

Parameters:

uniformPath - may be null if this information is not available.

tokens - A list of tokens that need to be preprocessed. The given list may get modified.

Returns:

A new list with the preprocessed tokens.

isGeneratedFromAbapKettensatzStatement

public static boolean isGeneratedFromAbapKettensatzStatement(UnmodifiableList<IToken> includedTokens)

Returns whether these tokens have been generated by the ABAP Preprocessor during a "Kettensatz" expansion. The expansion allows to write code like this: one two three : four five, six seven. which is expanded to one two three four five. one two three six seven. Of course, more segments are allowed and each segment can contain one or more tokens. Imporant are the colon, commas, and dot. Common use case: WRITE: x = 5, y = 1.
