Method Detail

internalMatch

protected int internalMatch(MatchingPhase phase,
                            boolean unread)
                     throws IOException,
                            DslException

Description copied from class: AbstractMatcher

Performs specific part of the match.

Specified by:

internalMatch in class AbstractMatcher

Parameters:

phase - Phase is already handled by main match method but is provided as information. It might not be used in general.

unread - Flag is already handled by main match method but is provided as information. It might not be used in general.

Returns:

weight

Throws:

IOException

DslException

internalGenericMatch

protected abstract int internalGenericMatch(MatchingPhase phase,
                                            boolean unread)
                                     throws IOException,
                                            DslException

Throws:

IOException

DslException

checkPreviousChar

protected boolean checkPreviousChar()
                             throws IOException

Checks if previous char from source matches the previous char pattern.
If no previous char can be read, the check is considered OK.

Throws:

IOException

checkFollowingChar

protected boolean checkFollowingChar()
                              throws IOException

Checks if next char from source matches the next char pattern.
If no next char can be read, the check is considered OK.

Throws:

IOException

getPreviousCharPatternMatchResult

public CharPatternMatchResult getPreviousCharPatternMatchResult()

Returns:

Result of match of PreviousCharPattern on the previous character, null if match not performed.

getFollowingCharPatternMatchResult

public CharPatternMatchResult getFollowingCharPatternMatchResult()

Returns:

Result of match of FollowingCharPattern on the next character, null if match not performed.
