matches(java.lang.String text)
Match the given
text against the pattern represented by the current instance,
as follows:
A * in the pattern matches any sequence of zero or more characters in the
text
A ? in the pattern matches exactly one character in the text
Any other character in the pattern must appear exactly as it is in the text
Notice: The mode flag of the current instance does not take any effect here. |
static boolean |
matches(StringPattern[] patterns,
java.lang.String text)
Match a given
text against an array of StringPattern s (which was
typically created by parseCombinedPattern(String) . |
static StringPattern[] |
parseCombinedPattern(java.lang.String combinedPattern)
Parse a "combined pattern" into an array of
StringPattern s. |

string is structured as follows:
combined-pattern := [ '+' | '-' ] pattern { ( '+' | '-' ) pattern }If a pattern is preceeded with a '-', then the

s (which was

The last matching pattern takes effect; if its mode is INCLUDE
, then
true
is returned, if its mode is EXCLUDE
, then false
is
returned.
If patterns
is PATTERNS_NONE
, or empty, or none of its patterns
matches, then false
is returned.
If patterns
is PATTERNS_ALL
, then true
is
returned.
For backwards compatibility, null
patterns are treated like
PATTERNS_NONE
.
