Constructor Detail

SystemResolver

public SystemResolver(TopLevelResolver inner,
              ExtensionInfo extInfo)

Create a caching resolver.

Parameters:

Method Detail

previous

public SystemResolver previous()

copy

public SystemResolver copy()

Specified by:

copy in interface Copy<CachingResolver>

Overrides:

copy in class CachingResolver

installInAll

public void installInAll(java.lang.String name,
                Named n)

installedInAll

public boolean installedInAll(java.lang.String name,
                     Named q)

packageExistsInCache

protected boolean packageExistsInCache(java.lang.String name)

Check if a package exists in the resolver cache.

packageExists

public boolean packageExists(java.lang.String name)

Check if a package exists.

Specified by:

packageExists in interface TopLevelResolver

cachePackage

protected void cachePackage(Package p)

checkType

public Type checkType(java.lang.String name)

Check if a type is in the cache, returning null if not.

Parameters:

name - The name to search for.

justAdded

public java.util.Collection<Named> justAdded()

clearAdded

public void clearAdded()

putAll

public void putAll(SystemResolver r)
            throws SemanticException

Throws:

SemanticException

find

public Named find(java.lang.String name)
           throws SemanticException

Find a type (or package) by name. For most code, this should be called with the Java source name (p.A.B), not the class file name (p.A$B). The exceptions are for resolving names in deserialized types and in types loaded from raw class files.

Specified by:

find in interface Resolver

Overrides:

find in class CachingResolver

Parameters:

name - The name to search for.

Throws:

SemanticException

install

public void install(java.lang.String name,
           Named q)

Description copied from class: CachingResolver

Install a qualifier in the cache.

Overrides:

install in class CachingResolver

Parameters:

name - The name of the qualifier to insert.

q - The qualifier to insert.

addNamed

public void addNamed(java.lang.String name,
            Named q)
              throws SemanticException

Overrides:

addNamed in class CachingResolver

Parameters:

name - The name of the qualifier to insert.

q - The qualifier to insert.

Throws:
