All Implemented Interfaces:

ISearchPath, IStatement, IHashable

public class PgFtsParser
extends PgAbstractStatement
implements ISearchPath

PostgreSQL full-text search parser implementation. Parsers break down documents into tokens and classify them into types. Each parser consists of several functions that handle different parsing phases.

Constructor Details

PgFtsParser

public PgFtsParser(String name)

Creates a new PostgreSQL FTS parser.

Parameters:

name - parser name

Method Details

getStatementType

public DbObjType getStatementType()

Description copied from interface: IStatement

Gets the type of this database object.

Specified by:

getStatementType in interface IStatement

Returns:

the database object type

getCreationSQL

public void getCreationSQL(SQLScript script)

Description copied from interface: IStatement

Generates the SQL statements needed to create this database object. This is an abstract method that must be implemented by subclasses to provide the specific CREATE SQL for each object type.

Specified by:

getCreationSQL in interface IStatement

Parameters:

script - the SQL script to append creation statements to

appendAlterSQL

public ObjectState appendAlterSQL(IStatement newCondition,
 SQLScript script)

Description copied from interface: IStatement

Fill script with object changes and return change type

Specified by:

appendAlterSQL in interface IStatement

Parameters:

newCondition - new object state

script - script to collect changes

Returns:

object change type

setStartFunction

public void setStartFunction(String startFunction)

setGetTokenFunction

public void setGetTokenFunction(String getTokenFunction)

setEndFunction

public void setEndFunction(String endFunction)

setLexTypesFunction

public void setLexTypesFunction(String lexTypesFunction)

setHeadLineFunction

public void setHeadLineFunction(String headLineFunction)

computeHash

public void computeHash(Hasher hasher)

Description copied from interface: IHashable

Computes the hash of the implementing object using the provided hasher. The implementation should call appropriate put methods on the hasher for all fields that should contribute to the hash value.

Specified by:

computeHash in interface IHashable

Parameters:

hasher - the hasher instance to use for hash computation

compare

public boolean compare(IStatement obj)

Description copied from class: AbstractStatement

This method does not account for nested child PgStatements. Shallow version of AbstractStatement.equals(Object)

Specified by:

compare in interface IStatement

Overrides:

compare in class AbstractStatement
