Default constructor.
-
FilterSet
protected FilterSet(FilterSet filterset)
Create a Filterset from another filterset.- Parameters:
filterset
- the filterset upon which this filterset will be based.
-
-
Method Detail
-
getFilters
protected java.util.Vector<FilterSet.Filter> getFilters()
Get the filters in the filter set.- Returns:
- a Vector of Filter instances.
-
getRef
protected FilterSet getRef()
Get the referenced filter set.- Returns:
- the filterset from the reference.
-
getFilterHash
public java.util.Hashtable<java.lang.String,java.lang.String> getFilterHash()
Gets the filter hash of the FilterSet.- Returns:
- The hash of the tokens and values for quick lookup.
-
setFiltersfile
public void setFiltersfile(java.io.File filtersFile) throws BuildException
Set the file containing the filters for this filterset.- Parameters:
filtersFile
- sets the filter file from which to read filters for this filter set.- Throws:
BuildException
- if there is an error.
-
setBeginToken
public void setBeginToken(java.lang.String startOfToken)
Set the string used to id the beginning of a token.- Parameters:
startOfToken
- The new Begintoken value.
-
getBeginToken
public java.lang.String getBeginToken()
Get the begin token for this filterset.- Returns:
- the filter set's begin token for filtering.
-
setEndToken
public void setEndToken(java.lang.String endOfToken)
Set the string used to id the end of a token.- Parameters:
endOfToken
- The new Endtoken value.
-
getEndToken
public java.lang.String getEndToken()
Get the end token for this filterset.- Returns:
- the filter set's end token for replacement delimiting.
-
setRecurse
public void setRecurse(boolean recurse)
Set whether recursive token expansion is enabled.- Parameters:
recurse
-boolean
whether to recurse.
