Field Details

pattern_names

public Vector pattern_names

Currently visible macro pattern names. For the i'th pattern variable, pattern_names.elementAt(i) is the name of the variable,

patternNesting

public StringBuffer patternNesting

Nesting of currently visible macro pattern names. For the i'th pattern variable, (int) patternNesting.charAt(i)/2 is the nesting (in terms of number of ellipsis that indicate the variable is repeated). The low-order bit indicates that if matched value is the car of the value saved in the vars array.

matchArray

public Declaration matchArray
