Constructor Details

KeywordAttributeImpl

public KeywordAttributeImpl()

Initialize this attribute with the keyword value as false.

Method Details

clear

public void clear()

Description copied from class: AttributeImpl

Clears the values in this AttributeImpl and resets it to its default value. If this implementation implements more than one Attribute interface it clears all.

Specified by:

clear in class AttributeImpl

copyTo

public void copyTo(AttributeImpl target)

Description copied from class: AttributeImpl

Copies the values from this Attribute into the passed-in target attribute. The target implementation must support all the Attributes this implementation supports.

Specified by:

copyTo in class AttributeImpl

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

isKeyword

public boolean isKeyword()

Description copied from interface: KeywordAttribute

Returns true if the current token is a keyword, otherwise false

Specified by:

isKeyword in interface KeywordAttribute

Returns:

true if the current token is a keyword, otherwise false

• KeywordAttribute.setKeyword(boolean)

setKeyword

public void setKeyword(boolean isKeyword)

Description copied from interface: KeywordAttribute

Marks the current token as keyword if set to true.

Specified by:

setKeyword in interface KeywordAttribute

Parameters:

isKeyword - true if the current token is a keyword, otherwise false .

See Also:

• KeywordAttribute.isKeyword()

reflectWith

public void reflectWith(AttributeReflector reflector)

Description copied from class: AttributeImpl

This method is for introspection of attributes, it should simply add the key/values this attribute holds to the given AttributeReflector.

Implementations look like this (e.g. for a combined attribute implementation):

   public void reflectWith(AttributeReflector reflector) {
     reflector.reflect(CharTermAttribute.class, "term", term());
     reflector.reflect(PositionIncrementAttribute.class, "positionIncrement", getPositionIncrement());
   }
 

If you implement this method, make sure that for each invocation, the same set of Attribute interfaces and keys are passed to AttributeReflector.reflect(java.lang.Class<? extends org.apache.lucene.util.Attribute>, java.lang.String, java.lang.Object) in the same order, but possibly different values. So don't automatically exclude e.g. null properties!

Specified by:

reflectWith in class AttributeImpl
