getClassLoader

public RecordedClassLoader getClassLoader()

Returns the class loader that defined the class.

If the bootstrap class loader is represented as null in the Java Virtual Machine (JVM), then null is also the return value of this method.

Returns:

the class loader defining this class, can be null

getName

public String getName()

Returns the fully qualified name of the class (for example, "java.lang.String").

Returns:

the class name, not null

getId

public long getId()

Returns a unique ID for the class.

The ID might not be the same between Java Virtual Machine (JVM) instances.

Returns:

a unique ID

getObjectSize

public int getObjectSize()

Returns the object size for the class.

The object size for instance class is accurate. But for the array class, it is a magic code 0x1111baba. The array object size can not be determined statically from the JVM klass information because array object size is affected by actual element length.

Returns:

the object size (instance object), or magic code 0x1111baba (array object)

isArray

public boolean isArray()

Checks whether the class is for instance or array.

Returns:

true or false
