skipWhitespace

private static int skipWhitespace(java.lang.String s,

convert

public static SimpleFilter convert(java.util.Map<java.lang.String,java.lang.Object> attrs)

Converts a attribute map to a filter. The filter is created by iterating over the map's entry set. If ordering of attributes is important (e.g., for hitting attribute indices), then the map's entry set should iterate in the desired order. Equality testing is assumed for all attribute types other than version ranges, which are handled appropriated. If the attribute map is empty, then a filter that matches anything is returned.

Parameters:

attrs - Map of attributes to convert to a filter.

Returns:

A filter corresponding to the attributes.
