Class AntPathMatcher.AntPatternComparator

java.lang.Object

org.springframework.util.AntPathMatcher.AntPatternComparator

All Implemented Interfaces:

java.util.Comparator<java.lang.String>

Enclosing class:

AntPathMatcher

protected static class AntPathMatcher.AntPatternComparator
extends java.lang.Object
implements java.util.Comparator<java.lang.String>

The default Comparator implementation returned by AntPathMatcher.getPatternComparator(String).

In order, the most "generic" pattern is determined by the following:

• if it's null or a capture all pattern (i.e. it is equal to "/**")
• if the other pattern is an actual match
• if it's a catch-all pattern (i.e. it ends with "**"
• if it's got more "*" than the other pattern
• if it's got more "{foo}" than the other pattern
• if it's shorter than the other pattern

Method Detail

compare

public int compare(java.lang.String pattern1,
                   java.lang.String pattern2)

Compare two patterns to determine which should match first, i.e. which is the most specific regarding the current path.

Specified by:

compare in interface java.util.Comparator<java.lang.String>

Returns:

a negative integer, zero, or a positive integer as pattern1 is more specific, equally specific, or less specific than pattern2.
