Method Detail

setFields

public void setFields(CharSequence[] fields)

Specified by:

setFields in interface MultiFieldAttribute

getFields

public CharSequence[] getFields()

Specified by:

getFields in interface MultiFieldAttribute

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

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Description copied from class: AttributeImpl

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object.

WARNING: For backwards compatibility this method is implemented as return reflectAsString(false). In Lucene 4.0 this default implementation will be removed. The reason for this is the problem of CharTermAttributeImpl.toString() that must return a string representation of the term's char sequence.

It is recommeneded to use AttributeImpl.reflectAsString(boolean) or AttributeImpl.reflectWith(org.apache.lucene.util.AttributeReflector) to get a well-defined output of AttributeImpl's internals.

Overrides:
