Constructor Detail

FTOrder

public FTOrder(InputInfo info,
               FTExpr expr)

Constructor.

Parameters:

info - input info (can be null)

expr - expression

Method Detail

filter

protected boolean filter(QueryContext qc,
                         FTMatch match,
                         FTLexer lexer)

Description copied from class: FTFilter

Evaluates the filter expression.

Specified by:

filter in class FTFilter

Parameters:

qc - query context

match - full-text match

lexer - lexer (can be null)

Returns:

result of check

copy

public FTExpr copy(CompileContext cc,
                   IntObjMap<Var> vm)

Description copied from class: Expr

Copies an expression. Used for inlining functions, or for copying static queries. It is utilized by VarRef.inline(org.basex.query.InlineContext), FuncItem.inline(org.basex.query.expr.Expr[], org.basex.query.CompileContext), Closure.inline(org.basex.query.InlineContext) and StaticFunc.inline(org.basex.query.expr.Expr[], org.basex.query.CompileContext).

Specified by:

copy in class FTExpr

Parameters:

cc - compilation context

vm - mapping from old variable IDs to new variable copies. Required by Closure.copy(org.basex.query.CompileContext, org.basex.util.hash.IntObjMap<org.basex.query.var.Var>) and VarRef.copy(org.basex.query.CompileContext, org.basex.util.hash.IntObjMap<org.basex.query.var.Var>)

Returns:

copied expression

toXml

public void toXml(QueryPlan plan)

Description copied from class: ExprInfo

Creates a query plan.

Overrides:

toXml in class FTExpr

Parameters:

plan - expression plan

toString

public void toString(QueryString qs)

Description copied from class: ExprInfo

Creates a query string.

Specified by:

toString in class ExprInfo

Parameters:

qs - query string builder
