ORIGINAL_BASE

static final String ORIGINAL_BASE

INSTANCE

private static final ShadedPrefixUtil INSTANCE

shadedBase

private final String shadedBase

The shaded equivalent of "org.apache.hadoop.hbase", or null if not in a shaded environment.

• Prefix-prepend shading (e.g., current package "a.b.c.org.apache.hadoop.hbase.ipc"): "a.b.c.org.apache.hadoop.hbase"
• Full-replacement shading (e.g., current package "shaded.hbase1.ipc"): "shaded.hbase1"

resolvedClassNames

private final ConcurrentHashMap<String,String> resolvedClassNames

Cache from original class name to its resolved (shaded or original) equivalent.

newInstance

static ShadedPrefixUtil newInstance(String currentPackageName)

getShadedBase

String getShadedBase()

applyShading

String applyShading(String className)

Maps an original HBase class name to its shaded equivalent by replacing the "org.apache.hadoop.hbase" prefix with the detected shaded base package. Returns the original class name unchanged if not in a shaded environment or if the class name does not start with the original HBase package. Note: this is a pure string transformation with no class loading. Use resolveShading(String) when class existence must be verified.

resolveShading

String resolveShading(String originalName)

Returns the effective class name for the given original HBase class name. Prefers the shaded class name when it can be loaded, and falls back to the original when the shaded class is not available (e.g., when exception classes are intentionally excluded from shading). The result is cached so that Class.forName is invoked at most once per distinct class name.
