Constructor Detail

CompoundMatchExpression

public CompoundMatchExpression(CompositeExpression ex)

Creates a path match expression.

Parameters:

ex - the CompositeExpression

Method Detail

getCompositeExpression

public CompositeExpression getCompositeExpression()

Returns the text used for creating the expression.

Returns:

the text

getEntryType

public TypeDescriptor<?> getEntryType()

Description copied from class: AbstractRuleMatchExpression

Returns the entry type over which this match expression will be able to iterate.

Specified by:

getEntryType in class AbstractRuleMatchExpression

Returns:

the entry type

accept

protected java.lang.Object accept(IMatchVisitor visitor)
                           throws VilException

Description copied from class: AbstractRuleMatchExpression

Accepts the given visitor for visiting.

Specified by:

accept in class AbstractRuleMatchExpression

Parameters:

visitor - the match visitor used for visiting

Returns:

the result of visiting (may be null)

Throws:

VilException - in case of visiting / evaluation errors

resolve

void resolve(Path resolved)

Sets the resolved value of the match expression, in particular in case of mixed expressions.

Parameters:

resolved - the resolved path

getResolved

public Path getResolved()

Returns the resolved expression.

Specified by:

getResolved in class AbstractPathRuleMatchExpression

Returns:

the resolved expression

evaluate

public Collection<?> evaluate(IExpressionVisitor evaluator)
                       throws VilException

Description copied from class: AbstractRuleMatchExpression

Evaluates this expression. Some subtypes may define some kind of value resolution, e.g., for match expressions. This must be called before!

Specified by:

evaluate in class AbstractRuleMatchExpression

Parameters:

evaluator - the expression evaluator (in case that an actual expression must be evaluated as part of this evaluation).

Returns:

the evaluation result

Throws:

VilException - in case that evaluation fails
