Field Detail

INCLUDE_FILTER_TOKEN_TYPES

public static final java.util.Set<ETokenType> INCLUDE_FILTER_TOKEN_TYPES

Tokens that identify when to filter out an INCLUDE statement. We only want to find statements of type INCLUDE foobar where foobar is another ABAP source object, but not INCLUDE TYPE foobar or INCLUDE STRUCTURE foobar. Since one may name their included source object like an ABAP keyword, we need to have a blacklist approach here.

Constructor Detail

AbapShallowParser

public AbapShallowParser()

Constructor.

Method Detail

isFilteredToken

protected boolean isFilteredToken(IToken token,
                                  IToken previousToken)

Template method that can be used to ignore/filter certain tokens. Default implementation ignores comments.

Overrides:

isFilteredToken in class ShallowParserBase<AbapShallowParser.EAbapParserStates>

previousToken - the last non-filtered token (can be used for context sensitive filtering). This may be null is no previous token exists.
