initFromDescriptor

public final void initFromDescriptor(String descriptor)

Given a packed descriptor listing methods and their type, populate the call site cache. The format of the methods portion of the descriptor is name1;type1;name2;type2 where type1 and type2 are a single capital letter N, F, V, or S for the four main call types. After the method portion, the other cache sizes are provided as a packed String of char values representing the numeric sizes. @see RuntimeCache#initOthers.

Parameters:

descriptor - The descriptor to use for populating call sites and caches

initOthers

public final void initOthers(String descriptor)

Given a packed descriptor of other cache sizes, construct the cache arrays The format of the descriptor is the actual size cast to char in this order:

1. scopeCount
2. inheritedSymbolCount
3. inheritedFixnumCount
4. inheritedConstantCount
5. inheritedRegexpCount
6. inheritedBigIntegerCount
7. inheritedVariableReaderCount
8. inheritedVariableWriterCount
9. inheritedBlockBodyCount
10. inheritedBlockCallbackCount
11. inheritedMethodCount
12. inheritedStringCount
