Field Detail

desc

protected final Utf8 desc

USE_CLASS_OBJECT_FIELD

public static final boolean USE_CLASS_OBJECT_FIELD

Constant Field Values

DISPLAY_SIZE

public static final int DISPLAY_SIZE

Constant Field Values

display

protected jq_Type[] display

The first two elements are the positive and negative cache, respectively. The remainder are the primary supertypes of this type ordered by the tree relation. This array should be inlined into the jq_Type object, hopefully. See paper "Fast subtype checking in the HotSpot JVM".

offset

protected int offset

The offset of our type in the display array if this is a primary type, or 0 or 1 if this is a secondary type. See paper "Fast subtype checking in the HotSpot JVM".

s_s_array

protected jq_Reference[] s_s_array

A reference to the secondary subtype array for this type. See paper "Fast subtype checking in the HotSpot JVM".

s_s_array_length

protected int s_s_array_length

The maximum index used in the secondary subtype array. See paper "Fast subtype checking in the HotSpot JVM".

TRACE

public static final boolean TRACE
