This resets the passedTokens and calls iReplaceTokens to
do the actual replacements.

It also maintains a list of currently used tokens, so we cannot
get into an infinite loop.

}

|
| public void | setFiltersfile(java.io.File filtersFile)Set the file containing the filters for this filterset.
if (isReference()) {
throw tooManyAttributes();
}
filtersFiles.add(filtersFile);
|
| public void | setOnMissingFiltersFile(org.apache.tools.ant.types.FilterSet$OnMissing onMissingFiltersFile)Set the behavior WRT missing filtersfiles.
this.onMissingFiltersFile = onMissingFiltersFile;

| public void | setRecurse(boolean recurse)Set whether recursive token expansion is enabled.
