Interface JavaSourceSet.ClasspathIndex

Enclosing class:

JavaSourceSet

public static interface JavaSourceSet.ClasspathIndex

SPI for JavaSourceSet.classpath backings that can resolve a fully-qualified name without scanning the entire list. The default ArrayList backing does not implement this; lazy partition-backed implementations (e.g., V4 LST deserialization) do, allowing recipes to query the classpath in O(log n) per partition rather than forcing materialization of every entry.

Implementations must accept the FQN in .-separated form (nested classes use ., not $); JavaSourceSet.findClasspathType(String) normalizes input before delegating.

Nested Class Summary

Nested Classes

Modifier and Type	Interface	Description
static interface	JavaSourceSet.ClasspathIndex.Subset	Lazy-aware result of withGavsRemoved(java.util.Set<java.lang.String>): a paired (classpath, gavToTypes) view onto the surviving partitions.

Method Summary

Modifier and Type	Method	Description
Optional<JavaType.FullyQualified>	findFullyQualified(String fqn)
Stream<JavaType.FullyQualified>	typesInPackage(String packageName)	Stream the types whose package name equals packageName (i.e., top-level types in the package — sub-package types and nested-class entries do not match).
default @Nullable JavaSourceSet.ClasspathIndex.Subset	withGavsRemoved(Set<String> gavKeysToRemove)	Return the (classpath, gavToTypes) subset with the given GAV keys removed, preserving lazy semantics where the implementation supports it.

Method Details

findFullyQualified

Optional<JavaType.FullyQualified> findFullyQualified(String fqn)

typesInPackage

Stream<JavaType.FullyQualified> typesInPackage(String packageName)

Stream the types whose package name equals packageName (i.e., top-level types in the package — sub-package types and nested-class entries do not match). Stream-based to allow short-circuit operations like Stream.anyMatch(java.util.function.Predicate<? super T>) to terminate before all partitions are scanned.

withGavsRemoved

default @Nullable JavaSourceSet.ClasspathIndex.Subset withGavsRemoved(Set<String> gavKeysToRemove)

Return the (classpath, gavToTypes) subset with the given GAV keys removed, preserving lazy semantics where the implementation supports it. Default returns null, signalling the caller to fall back to identity-based filtering. Lazy backings that track GAV provenance can implement this to skip materialization of the entire classpath when recipes call JavaSourceSet.removeTypesMatching(String, String) or JavaSourceSet.removeTypesForGav(String).
