Constructor	Description
FlagsAttributeImpl()	Initialize this attribute with no bits set

Method Summary

Modifier and Type	Method	Description

Constructor Detail

FlagsAttributeImpl

public FlagsAttributeImpl()

Initialize this attribute with no bits set

Method Detail

getFlags

public int getFlags()

Description copied from interface: FlagsAttribute

Get the bitset for any bits that have been set.

Specified by:

getFlags in interface FlagsAttribute

Returns:

The bits

See Also:

FlagsAttribute.getFlags()

setFlags

public void setFlags(int flags)

Description copied from interface: FlagsAttribute

Set the flags to a new bitset.

Specified by:

setFlags in interface FlagsAttribute

See Also:

FlagsAttribute.getFlags()

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

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

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

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
