Constructor Detail

Embed

public Embed(java.lang.String pre,
             java.lang.String post,
             int prio)

creates an FaAction with the given priority which embeds the matched text into the given strings. For example new Embed("<x>", "</x>", 0) arranges for the match to be XML tagged with <x>. The parameters may not be null, but may be the empty string.

Although the functionality of this action is covered by the more general Printf, it is believed that this specific implementation is slightly more efficient.

Embed

public Embed(java.lang.String pre,
             java.lang.String post)

calls the 3 parameter constructor with priority==0.

Method Detail

invoke

public void invoke(java.lang.StringBuilder out,
                   int start,
                   DfaRun runner)

Description copied from interface: FaAction

is called by methods of DfaRun in case of a match. Parameter yytext contains the matching text from position start onwards. The callback may change the whole of yytext, but the under most circumstances, only the matching text should be changed. Parameter runner is the DfaRun object which called this function. Of interest are its fields DfaRun.clientData and DfaRun.collect.
