java.lang.Object
   org.apache.lucene.index.Term

Term
final public class Term implements Comparable,java.io.Serializable(Code)
A Term represents a word from text. This is the unit of search. It is composed of two elements, the text of the word, as a string, and the name of the field that the text occured in, an interned string. Note that terms may represent more than words from text fields, but also things like dates, email addresses, urls, etc.


Field Summary
 Stringfield
    
 Stringtext
    

Constructor Summary
public  Term(String fld, String txt)
     Constructs a Term with the given field and text.

Note that a null field or null text value results in undefined behavior for most Lucene APIs that accept a Term parameter.

 Term(String fld, String txt, boolean intern)
    

Method Summary
public  intcompareTo(Object other)
    
final public  intcompareTo(Term other)
     Compares two terms, returning a negative integer if this term belongs before the argument, zero if this term is equal to the argument, and a positive integer if this term belongs after the argument.
public  TermcreateTerm(String text)
    
final public  booleanequals(Object o)
     Compares two terms, returning true iff they have the same field and text.
final public  Stringfield()
     Returns the field of this term, an interned string.
final public  inthashCode()
     Combines the hashCode() of the field and the text.
final  voidset(String fld, String txt)
     Resets the field and text of a Term.
final public  Stringtext()
     Returns the text of this term.
final public  StringtoString()

Constructor Detail
Term
public Term(String fld, String txt)(Code)
Constructs a Term with the given field and text.

Note that a null field or null text value results in undefined behavior for most Lucene APIs that accept a Term parameter.




Term
Term(String fld, String txt, boolean intern)(Code)




Method Detail
compareTo
public int compareTo(Object other)(Code)



compareTo
final public int compareTo(Term other)(Code)
Compares two terms, returning a negative integer if this term belongs before the argument, zero if this term is equal to the argument, and a positive integer if this term belongs after the argument. The ordering of terms is first by field, then by text.



createTerm
public Term createTerm(String text)(Code)
Optimized construction of new Terms by reusing same field as this Term - avoids field.intern() overhead
Parameters:
  text - The text of the new term (field is implicitly same as this Term instance) A new Term



equals
final public boolean equals(Object o)(Code)
Compares two terms, returning true iff they have the same field and text.



field
final public String field()(Code)
Returns the field of this term, an interned string. The field indicates the part of a document which this term came from.



hashCode
final public int hashCode()(Code)
Combines the hashCode() of the field and the text.



set
final void set(String fld, String txt)(Code)
Resets the field and text of a Term.



text
final public String text()(Code)
Returns the text of this term. In the case of words, this is simply the text of the word. In the case of dates and other types, this is an encoding of the object as a string.



toString
final public String toString()(Code)
