Method Details

value

public Value value(QueryContext qc)
            throws QueryException

Description copied from class: Expr

Evaluates the expression and returns the resulting value. If this method is not implemented, Expr.item(QueryContext, InputInfo) must be implemented instead.

Overrides:

value in class ParseExpr

Parameters:

qc - query context

Returns:

value

Throws:

QueryException - query exception

opt

protected Expr opt(CompileContext cc)
            throws QueryException

Description copied from class: StandardFunc

Performs function specific optimizations.

Overrides:

opt in class StandardFunc

Parameters:

cc - compilation context

Returns:

optimized or original expression

Throws:

QueryException - query exception

whitespaces

public boolean whitespaces()

Indicates if a default whitespace tokenization is to be performed.

Returns:

result of check

pattern

protected final Pattern pattern(Expr regex,
 Expr modifier,
 QueryContext qc,
 boolean check)
                         throws QueryException

Returns a regular expression pattern.

Parameters:

regex - pattern

modifier - modifier item

qc - query context

check - check result for empty strings

Returns:

pattern modifier

Throws:

QueryException - query exception

regExpr

protected final org.basex.query.func.fn.RegEx.RegExpr regExpr(Expr regex,
 Expr modifier,
 QueryContext qc,
 boolean check)
                                                       throws QueryException

Returns a regular expression pattern.

Parameters:

regex - pattern

modifier - modifier item

qc - query context

check - check result for empty strings

Returns:

pattern modifier

Throws:

QueryException - query exception
