Class PlSqlInterrogatorFactory

java.lang.Object

oracle.javatools.db.plsql.PlSqlInterrogatorFactory

public class PlSqlInterrogatorFactory
extends java.lang.Object

A utility factory class to create PlSqlInterrogators. Whilst a PlSqlInterrogator can be created directly for any String representing PL/SQL, this factory makes use of the internal sourceID property of a PlSqlSourceObject to minimise the size of the key used when caching PlSqlInterrogators for a given source string.

Method Detail

getInterrogator

public static PlSqlInterrogator getInterrogator(SourceObject source)

Return a PlSqlInterrogator for the given PlSqlSourceObject.

PlSqlSourceObjects maintain an internal unique key each time the source changes on the object, and this is used to find a PlSqlInterrogator (see PlSqlInterrogator.findOrCreate(String,String)). If a PlSqlInterrogator for that key is already cached for the key, it will be returned, otherwise a new PlSqlInterrogator will be created, and the source of the PlSqlSourceObject parsed into PlSqlTokens and PlSqlFragments.

Parameters:

source - The PlSqlSourceObject.

Returns:

a PlSqlInterrogator that will provide information about the given source

getInterrogator

public static PlSqlInterrogator getInterrogator(SourceObject source,
                                Holder<PlSqlInterrogator> holder)

Return a PlSqlInterrogator for the given PlSqlSourceObject.

PlSqlSourceObjects maintain an internal unique key each time the source changes on the object, and this is used to find a PlSqlInterrogator (see PlSqlInterrogator.findOrCreate(String,String)). If a PlSqlInterrogator for that key is already cached for the key, it will be returned, otherwise a new PlSqlInterrogator will be created, and the source of the PlSqlSourceObject parsed into PlSqlTokens and PlSqlFragments. Optionally a Holder<PlSqlInterrogator> can be passed in. If not null, the PlSqlInterrogator that will be returned is placed in the Holder before the interrogation process starts. (see PlSqlInterrogator.findOrCreate(String,String,Holder)).

Parameters:

source - The PlSqlSourceObject.

holder -

Returns:

a PlSqlInterrogator that will provide information about the given source
