Method Detail

register

public static void register(java.lang.Class<? extends ITargetSelectorDynamic> type,
                            java.lang.String namespace)

Register a dynamic target selector class. The supplied class must be decorated with an ITargetSelectorDynamic.SelectorId annotation for registration to succeed.

Parameters:

type - ITargetSelectorDynamic to register

namespace - namespace for SelectorId

parseAndValidate

public static ITargetSelector parseAndValidate(IAnnotationHandle annotation,
                                               ISelectorContext context)
                                        throws InvalidSelectorException

Parse a target selector from the supplied annotation and perform validation

Parameters:

annotation - Annotation to parse target selector from

context - Context to use for reference mapping

Returns:

parsed target selector

Throws:

InvalidSelectorException

parseAndValidate

public static ITargetSelector parseAndValidate(java.lang.String string,
                                               ISelectorContext context)
                                        throws InvalidSelectorException

Parse a target selector from a string and perform validation

Parameters:

string - String to parse target selector from

context - Context to use for reference mapping

Returns:

parsed target selector

Throws:

InvalidSelectorException

parseAndValidate

public static java.util.Set<ITargetSelector> parseAndValidate(java.lang.Iterable<?> selectors,
                                                              ISelectorContext context)
                                                       throws InvalidSelectorException

Parse a collection of target selector representations (strings, annotations, class literals) into selectors.

Parameters:

selectors - Selectors to parse

context - Selection context

Returns:

parsed collection of selectors, uses LinkedHashSet to preserve parse ordering

Throws:

InvalidSelectorException

parse

public static java.util.Set<ITargetSelector> parse(java.lang.Iterable<?> selectors,
                                                   ISelectorContext context)

Parse a collection of target selector representations (strings, annotations, class literals) into selectors.

Parameters:

selectors - Selectors to parse

context - Selection context

Returns:

parsed collection of selectors, uses LinkedHashSet to preserve parse ordering

parse

public static java.util.Set<ITargetSelector> parse(java.lang.Iterable<?> selectors,
                                                   ISelectorContext context,
                                                   java.util.Set<ITargetSelector> parsed)

Parse a collection of target selector representations (strings, annotations, class literals) into selectors and store them in the provided collection.

Parameters:

selectors - Selectors to parse

context - Selection context

parsed - Collection to add parsed selectors to, initialised as a LinkedHashSet if null

Returns:

the same collection passed in via the parsed parameter, for convenience

parse

public static ITargetSelector parse(IAnnotationHandle annotation,
                                    ISelectorContext context)

Parse a target selector from the supplied annotation

Parameters:

annotation - String to parse target selector from

context - Context to use for reference mapping

Returns:

parsed target selector

parse

public static ITargetSelector parse(java.lang.String string,
                                    ISelectorContext context)

Parse a target selector from a string

Parameters:

string - String to parse target selector from

context - Context to use for reference mapping

Returns:

parsed target selector

parseName

public static java.lang.String parseName(java.lang.String name,
                                         ISelectorContext context)

Parse a target selector from the supplied name, and then return the name of the match. This is used mainly to remap input names in the same context as a selector without needing the selector itself. If the supplied name does not successfully parse to a name-based selector, then the name is returned unchanged.

Parameters:

name - Name to parse

context - Mixin context

Returns:

remapped name or original name

run

public static <TNode> TargetSelector.Result<TNode> run(ITargetSelector selector,
                                                       java.lang.Iterable<ElementNode<TNode>> nodes)

Run query on supplied target nodes

Type Parameters:

TNode - Node type

Parameters:

selector - Target selector

nodes - Node collection to enumerate

Returns:

query result

run

public static <TNode> TargetSelector.Result<TNode> run(java.lang.Iterable<ITargetSelector> selector,
                                                       java.lang.Iterable<ElementNode<TNode>> nodes)

Run query on supplied target nodes

Type Parameters:
