Description
| Interface Summary | |
|---|---|
| CodeGenUtils.EmissionCallback | A class that emits source code of some time when activated. |
| CommentEmitter | |
| GlueEmitter | Specifies the interface by which GlueGen requests glue code to be generated. |
| GlueEmitterControls | Specifies the interface by which a GlueEmitter can request additional information from the glue generator. |
| SymbolFilter | Provides a mechanism by which the GlueEmitter can look at all of the #defines, enum values and function symbols and perform certain filtering and processing which requires all of them to be visible simultaneously. |
| Class Summary | |
|---|---|
| ArrayTypes | Convenience class containing the Class objects corresponding to arrays of
various types (e.g., ArrayTypes.booleanArrayClass is the Class of Java type
"boolean[]"). |
| CMethodBindingEmitter | Emits the C-side component of the Java<->C JNI binding. |
| CMethodBindingEmitter.DefaultCommentEmitter | Class that emits a generic comment for CMethodBindingEmitters; the comment includes the C signature of the native method that is being bound by the emitter java method. |
| CodeGenUtils | |
| ConstantDefinition | Represents the definition of a constant which was provided either via a #define statement or through an enum definition. |
| DebugEmitter | Debug emitter which prints the parsing results to standard output. |
| FunctionEmitter | |
| FunctionEmitter.EmissionModifier | |
| GlueGen | Glue code generator for C functions and data structures. |
| JavaConfiguration | Parses and provides access to the contents of .cfg files for the JavaEmitter. |
| JavaEmitter | |
| JavaMethodBindingEmitter | An emitter that emits only the interface for a Java<->C JNI binding. |
| JavaType | Describes a java-side representation of a type that is used to represent the same data on both the Java-side and C-side during a JNI operation. |
| Logging | |
| MethodBinding | Represents the binding of a C function to a Java method. |
| ReferencedStructs | |
| TypeInfo | Utility class for handling Opaque directives for JavaEmitter. |
| Enum Summary | |
|---|---|
| JavaEmitter.EmissionStyle | Style of code emission. |
| JavaEmitter.MethodAccess | Access control for emitted Java methods. |

Warning: Try to avoid unspecified bit sized types, especially long, since it differs on Unix and Windows!
Notes:
Compounds (structures) are aligned naturally, i.e. their inner components are aligned
and are itself aligned to it's largest element.
remainder = offset % alignmentsince alignment is a multiple of 2
-> x % 2n == x & (2n - 1)remainder = offset & ( alignment - 1 )
padding = (remainder > 0) ? alignment - remainder : 0 ;
aligned_offset = offset + padding ;
typedef struct {
char fill; // nibble one byte
// padding to align s1: padding_0
type_t s1; //
} test_struct_type_t;
padding_0 = sizeof(test_struct_type_t) - sizeof(type_t) - sizeof(char) ;
alignmentOf(type_t) = sizeof(test_struct_type_t) - sizeof(type_t) ;
