I come with that :
in SyntaxChecker base class :
public abstract class SyntaxChecker extends LoadableSchemaObject
{
...
/**
* A static Builder for this class
*/
public abstract static class SCBuilder<SC>
{
/** The SyntaxChecker OID */
protected String oid;
/**
* The Builder constructor
*/
protected SCBuilder( String oid )
{
this.oid = oid;
}
/**
* Set the SyntaxChecker's OID
*
* @param oid The OID
* @return The Builder's Instance
*/
public SCBuilder<SC> setOid( String oid )
{
this.oid = oid;
return this;
}
public abstract SC build();
}
In BooleanSyntaxChecker inherited class :
public class BooleanSyntaxChecker extends SyntaxChecker
{
/**
* A static instance of BooleanSyntaxChecker
*/
public static final BooleanSyntaxChecker INSTANCE = new
BooleanSyntaxChecker( SchemaConstants.BOOLEAN_SYNTAX );
/** A static instance of the builder */
private static final Builder BUILDER_INSTANCE = new Builder();
/**
* A static Builder for this class
*/
public static class Builder extends SCBuilder<BooleanSyntaxChecker>
{
/**
* The Builder constructor
*/
private Builder()
{
super( SchemaConstants.BOOLEAN_SYNTAX );
}
/**
* Create a new instance of BooleanSyntaxChecker
* @return A new instance of BooleanSyntaxChecker
*/
@Override
public BooleanSyntaxChecker build()
{
return new BooleanSyntaxChecker( oid );
}
}
/**
* Creates a new instance of BooleanSyntaxChecker.
*/
private BooleanSyntaxChecker( String oid )
{
super( oid );
}
/**
* @return An instance of the Builder for this class
*/
public static Builder builder()
{
return BUILDER_INSTANCE;
}
