public class MethodBinding extends Object
Constructor and Description |
---|
MethodBinding(FunctionSymbol sym)
Constructor for calling a C function.
|
MethodBinding(FunctionSymbol sym,
JavaType containingType,
Type containingCType)
Constructor for calling a function pointer contained in a
struct.
|
MethodBinding(MethodBinding bindingToCopy)
Constructs a new MethodBinding that is an exact clone of the
argument, including the java return type and java argument
types.
|
Modifier and Type | Method and Description |
---|---|
void |
addAliasedName(String name) |
void |
addJavaArgumentType(JavaType type) |
boolean |
argumentsUseNIO()
Returns true if any of the outgoing arguments in the method's
signature require conversion or checking due to the use of New
I/O.
|
void |
clearThisPointer()
Clears any record of a this pointer for this MethodBinding.
|
protected void |
computeSignatureProperties()
Computes summary information about the method's C and Java
signatures.
|
boolean |
equals(Object obj) |
protected String |
erasedTypeDescriptor(JavaType type,
boolean eraseBufferAndArrayTypes,
boolean skipBuffers) |
void |
findThisPointer()
Find the leftmost argument matching the type of the containing
type (for function pointer MethodBindings) and record that as a
"this" pointer, meaning that it does not need to be explicitly
passed at the Java level.
|
Collection<String> |
getAliasedNames() |
String |
getArgumentName(int i)
Returns either the argument name specified by the underlying
FunctionSymbol or a fabricated argument name based on the
position.
|
Type |
getCArgumentType(int i) |
Type |
getContainingCType()
Retrieves the containing C type of this MethodBinding if it is for
a function pointer contained in a struct.
|
JavaType |
getContainingType()
Retrieves the containing type of this MethodBinding if it is for
a function pointer contained in a struct.
|
Type |
getCReturnType() |
FunctionSymbol |
getCSymbol() |
String |
getDescriptor(boolean forImplementingMethodCall,
boolean eraseBufferAndArrayTypes)
Returns a String containing the descriptor (signature in
internal format) of this MethodBinding as it will be
emitted.

getJavaArgumentType(int i) |
JavaType |
getJavaReturnType() |
String |
getName() |
int |
getNumArguments() |
String |
getOrigName() |
boolean |
hasContainingType()
Indicates whether this MethodBinding is for a function pointer
contained in a struct.
|
int |
hashCode() |
boolean |
isArgumentThisPointer(int i)
Indicates whether the ith argument to this MethodBinding
is actually a "this" pointer.
|
boolean |
needsNIOWrappingOrUnwrapping()
Returns true if the function needs NIO-related
wrapping/unwrapping or conversion of various arguments.
|
void |
renameMethodName(String name)
Supports renaming C function in Java binding.
|
MethodBinding |
replaceJavaArgumentType(int argumentNumber,
JavaType newArgType)
Creates a new MethodBinding replacing the specified Java
argument type with a new argument type.
|
void |
setJavaReturnType(JavaType type) |
boolean |
signatureCanUseIndirectNIO()
Returns true if it is possible for any of the outgoing arguments
to be indirect NIO buffers.
|
boolean |
signatureUsesArraysOfCompoundTypeWrappers()
Returns true if the return type or any of the outgoing arguments
in the method's signature use arrays of "compound type wrappers",
or NIO-based wrappers for C data structures.
|
boolean |
signatureUsesCArrays()
Returns true if the return type or any of the outgoing arguments
in the method's signature represent C arrays.
|
boolean |
signatureUsesCompoundTypeWrappers()
Returns true if the return type or any of the outgoing arguments
in the method's signature use "compound type wrappers", or
NIO-based wrappers for C data structures.
|
boolean |
signatureUsesCPrimitivePointers()
Returns true if the return type or any of the outgoing arguments
in the method's signature represent C primitive pointers.
|
boolean |
signatureUsesCVoidPointers()
Returns true if the return type or any of the outgoing arguments
in the method's signature represent C void* pointers.
|
boolean |
signatureUsesJavaPrimitiveArrays()
Returns true if the return type or any of the outgoing arguments
in the method's signature represent Java primitive arrays.
|
boolean |
signatureUsesNIO()
Returns true if the return type or any of the outgoing arguments
in the method's signature require conversion or checking due to
the use of New I/O.
|
String |
toString()
Returns the signature of this binding.
