getJBooleanback to summary
public boolean getJBoolean(Address addr) throws UnmappedAddressException, UnalignedAddressException, WrongTypeException

Implements sun.jvm.hotspot.types.Field.getJBoolean.

Doc from sun.jvm.hotspot.types.Field.getJBoolean.

These accessors require that the field be nonstatic; otherwise, a WrongTypeException will be thrown. Note that type checking is not performed by these accessors in order to allow manual type coercion of field data. For better protection when accessing primitive fields, use the get(Type)Field accessors in Type.java.

NOTE that the Address passed in to these routines may, in fact, be an OopHandle. Specifically, in a reflective system, dereferencing operations applied to the OopHandle must be performed atomically with respect to GC.

See @see CIntegerType for a description of why all C integer types are bundled into the category "CIntegerType".
