Constructor Details

Resolver4

public Resolver4(MessageReceiver<SimpleMessage<XMLDocumentIdentifier>> msgoutput,
 ModuleRegistry moduleRegistry,
 Module rootModule,
 int verbosity)

Central service providing method. Create a new instance for one particular raw root module. Afterwards resolveAllPublics() must be called. (Can only by used once.)

Method Details

resolveAllPublics_partial

@Opt
public @Opt ResolvedModule resolveAllPublics_partial()

Allows the module to contain references which are already resolved. This happens when a resolved module is embedded into the generic xslt module. This mode ignores resolved references, while the other mode resolveAllPublics() throws an IllegalStateException.

resolveAllPublics

@Opt
public @Opt ResolvedModule resolveAllPublics()

error

protected void error(@Opt
 @Opt Location<XMLDocumentIdentifier> loc,
 String txt,
 Object... obj)

warning

protected void warning(@Opt
 @Opt Location<XMLDocumentIdentifier> loc,
 String txt,
 Object... obj)

hint

protected void hint(@Opt
 @Opt Location<XMLDocumentIdentifier> loc,
 String txt,
 Object... obj)

TRACE

protected void TRACE(String s)

TRACE

protected void TRACE(Supplier<String> s)

newImportContext

ImportContext newImportContext(@Opt
 @Opt ImportContext predec,
 ImportItem importItem,
 String moduleAddress,
 Module rawModule,
 String key)

compoundKeyX

static String compoundKeyX(ImportContext ic)

Return compound string which reflects the path of imports reaching this context. This variant returns a symbolic name for the top-level module. Is NOT called recursively but uses #compoundKey().

compoundKey

static String compoundKey(ImportContext ic)

Return compound string which reflects the path of imports reaching this context. This variant returns empty string for the top-level module.

compoundKey

static String compoundKey(ImportContext ic,
 Definition def)

Return the compound string for the definition instantiation in this context.

findBinding

@Opt
protected static <T> @Opt Binding findBinding(@Opt
 @Opt Binding binding,
 String id)

equivalentBindings

static boolean equivalentBindings(Binding shorter,
 Binding longer,
 Set<String> copies)

Tests whether longer is semantically equivalent to shorter, and shorter is a prefix of longer.

installCode

protected void installCode(Classifier.Instance inst)

action

public void action(Subst subst)

Overrides:

action in class Rewrite

action

public void action(Insertion ins)

"rewriteFields()" is NOT called on this level, but "match()" on the contained expression, with a further "FlattenContext" added to their stack. Thus the result of rewriting is the expansion of that expression, and the Insertion operator itself is eliminated. (NEW insertions containing only one single reference will be synthesized whenever a cycle is detected.)

Overrides:

action in class Rewrite

rewriteFields

protected void rewriteFields(GrUnary clone)

Overrides:

rewriteFields in class Rewrite

rewriteFields

protected void rewriteFields(Alt clone)

Overrides:

rewriteFields in class Rewrite

rewriteFields

protected void rewriteFields(Perm clone)

Overrides:

rewriteFields

protected void rewriteFields(Seq clone)

Overrides:

rewriteFields in class Rewrite

rewriteFields

protected void rewriteFields(CharBinary clone)

Overrides:

rewriteFields in class Rewrite

rewriteFields

protected void rewriteFields(ParseParticle clone)

Rewrite sub-expression and propagate "empty" upwards.

Overrides:

rewriteFields in class Rewrite

rewriteFields

protected void rewriteFields(CharSetConst clone)

Simply clones.

Overrides:

rewriteFields in class Rewrite

rewriteFields

protected void rewriteFields(StringConst clone)

Simply clones.

Overrides:

Overrides:

visitPossiblyImportedDefinition

protected void visitPossiblyImportedDefinition(Location<XMLDocumentIdentifier> loc,

protected void visitPossiblyImportedDefinition(Location<XMLDocumentIdentifier> loc,
 Reference currentReference,
 String... prefs)

switchModuleRest

protected void switchModuleRest(Location<XMLDocumentIdentifier> loc,
 Reference currentReference,
 String... prefs)

Discard the first prefix, as reflected in the global state, and call resolution for the rest components of the identifier.

loadImportedModule

@Opt
protected @Opt ImportContext loadImportedModule(Location<XMLDocumentIdentifier> loc,
 ImportContext ic,
 String pref)

Create and store a new import context and load the uninstantiated module text, if not yet done.

 Reference currentReference,
 String... prefs)
