Method Details

of

public static PatternExpression of(String regex,
 String pattern)

getJavaPatternString

public String getJavaPatternString()

Returns a Java Pattern-compatible regular expression (pattern). Returned string performs equivalent matching in terms of enforcement, but it may have a structure completely different from the one in YANG model.

Returns:

string Java Pattern regular expression

getRegularExpressionString

public String getRegularExpressionString()

Returns a raw regular expression as it was declared in a source. This string conforms to XSD regular expression syntax, which is notably different from Java's Pattern string.

Returns:

argument of pattern statement as it was declared in YANG model.

intern

public PatternExpression intern()

Returns an interned instance of this expression.

Returns:

A shared interned instance.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(@Nullable Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
