             throws IOException

Specified by:

writeTo in interface Writeable

Throws:

IOException

doCreateAutomaton

protected org.apache.lucene.util.automaton.Automaton doCreateAutomaton(boolean ignoreCase)

asJavaRegex

public String asJavaRegex()

Description copied from interface: StringPattern

Returns the pattern in (Java) regex format.

Specified by:

asJavaRegex in interface StringPattern

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

pattern

public String pattern()

Description copied from interface: StringPattern

Returns the pattern as it was defined by the user.

Specified by:

pattern in interface StringPattern

nodeString

public void nodeString(StringBuilder sb,
 Node.NodeStringFormat format,
 NodeStringMapper mapper)

Renders the regex quoted, routing maximal literal runs through mapper.column while passing regex metacharacters (. * + ? ( ) [ ] {@literal { } } | ^ $ \) through unchanged. Every non-metacharacter ends up inside a column call, so no literal content survives anonymization; under NodeStringMapper.IDENTITY this reproduces the raw regex.

Specified by:

nodeString in interface NodeStringRenderable

Overrides:

nodeString in class AbstractStringPattern
