Package org.umlg.sqlg.predicate

Class FullText

java.lang.Object

org.umlg.sqlg.predicate.FullText

All Implemented Interfaces:

BiPredicate<String,String>, org.apache.tinkerpop.gremlin.process.traversal.PBiPredicate<String,String>

public class FullText
extends Object
implements org.apache.tinkerpop.gremlin.process.traversal.PBiPredicate<String,String>

Full text match predicate This is very postgresql oriented: - configuration is whatever was used to create the index - plain is to switch to plainto_tsquery (no need to use operators, etc.)

FullText

public FullText(String configuration,
 String query,
 boolean plain)

full constructor

Parameters:

configuration - the full text configuration

query - the left hand side query if specified

plain - use plain mode

Method Details

fullTextMatch

public static org.apache.tinkerpop.gremlin.process.traversal.P<String> fullTextMatch(String configuration,
 String value)

Build full text matching predicate (use in has(column,...))

Parameters:

configuration - the full text configuration to use

value - the value to search for

Returns:

the predicate

fullTextMatch

public static org.apache.tinkerpop.gremlin.process.traversal.P<String> fullTextMatch(String configuration,
 boolean plain,
 String value)

Build full text matching predicate (use in has(column,...))

Parameters:

configuration - the full text configuration to use

plain - should we use plain mode?

value - the value to search for

Returns:

the predicate

fullTextMatch

public static org.apache.tinkerpop.gremlin.process.traversal.P<String> fullTextMatch(String configuration,
 boolean plain,
 String query,
 String value)

Build full text matching predicate (use in where(...))

Parameters:

configuration - the full text configuration to use

plain - should we use plain mode?

query - the actual query (left hand side)

value - the value to search for

Returns:

the predicate

fullTextMatch

public static org.apache.tinkerpop.gremlin.process.traversal.P<String> fullTextMatch(String configuration,
 boolean plain,
 List<String> columns,
 String value)

Build full text matching predicate (use in where(...)) Uses several columns for text search. This assumes PostgreSQL and concatenates column names with a space in between just like we would by default build the index

Parameters:

configuration - the full text configuration to use

plain - should we use plain mode?

columns - the columns to query

value - the value to search for

Returns:

the predicate

getConfiguration

public String getConfiguration()

isPlain

public boolean isPlain()

getQuery

public String getQuery()

test

public boolean test(String first,
 String second)

Specified by:

test in interface BiPredicate<String,String>

toString

public String toString()

Overrides:

toString in class Object
