Public Methods

Method	Description
CreateObjectArrayFromInstanceParameters ( this g, LocalBuilder array, Type parameters ) : void	Emits the IL to create a new array (OpCodes.Newarr) of objects and fills it with the actual arguments of the method (parameters are boxed if needed) skipping the very first one: this must be used only inside a method with System.Reflection.CallingConventions.HasThis set.
LdArg ( this g, int i ) : void	Emits the IL to push (OpCodes.Ldarg) the actual argument at the given index onto the stack.
LdArgBox ( this g, ParameterInfo p ) : void	Emits a LdArg with an optional OpCodes.Box if p's type is a value type or a generic parameter (after a OpCodes.Ldobj if the parameter is by ref). Handles static or instance methods (takes care of System.Reflection.CallingConventions.HasThis bit of the method's CallingConvention).
LdArgBox ( this g, int idxParameter, Type parameterType ) : void	Emits a LdArg with a OpCodes.Box if parameterType is a value type or a generic parameter (after a OpCodes.Ldobj if the parameter is by ref).
LdInt32 ( this g, int i ) : void	Emits the IL to push the integer (emits the best opcode depending on the value: OpCodes.Ldc_I4_0 or OpCodes.Ldc_I4_M1 for instance) value onto the stack.
LdLoc ( this g, LocalBuilder local ) : void	Emits the IL to push (OpCodes.Ldloc) the given local on top of the stack.
RepushActualParameters ( this g, bool startAtArgument0, int count ) : void	Emits the optimal IL to push the actual parameter values on the stack (OpCodes.Ldarg_0... OpCodes.Ldarg).
StArg ( this g, int i ) : void	Emits the IL to pop (OpCodes.Starg) the top of the stack into the actual argument at the given index.
StLoc ( this g, LocalBuilder local ) : void	Emits the IL to pop (OpCodes.Stloc) the top of the stack into a local variable.
StoreDefaultValueForOutParameter ( this g, ParameterInfo byRefParameter ) : void	Emits code that sets the parameter (that must be a 'ref' or 'out' parameter) to the default of its type. Handles static or instance methods and value or reference type.

Method Details

CreateObjectArrayFromInstanceParameters() public static method

Emits the IL to create a new array (OpCodes.Newarr) of objects and fills it with the actual arguments of the method (parameters are boxed if needed) skipping the very first one: this must be used only inside a method with System.Reflection.CallingConventions.HasThis set.

public static CreateObjectArrayFromInstanceParameters ( this g, LocalBuilder array, Type parameters ) : void
g	this	This object.
array	System.Reflection.Emit.LocalBuilder	The local variable.
parameters	System.Type	Type of the method parameters.
return	void

LdArg() public static method

Emits the IL to push (OpCodes.Ldarg) the actual argument at the given index onto the stack.

public static LdArg ( this g, int i ) : void
g	this	This object.
i	int	Parameter index (0 being the 'this' for instance method).
return	void

LdArgBox() public static method

Emits a LdArg with an optional OpCodes.Box if p's type is a value type or a generic parameter (after a OpCodes.Ldobj if the parameter is by ref). Handles static or instance methods (takes care of System.Reflection.CallingConventions.HasThis bit of the method's CallingConvention).

public static LdArgBox ( this g, ParameterInfo p ) : void
g	this	This object.
p	System.Reflection.ParameterInfo	Parameter of the current method.
return	void

LdArgBox() public static method

Emits a LdArg with a OpCodes.Box if parameterType is a value type or a generic parameter (after a OpCodes.Ldobj if the parameter is by ref).

public static LdArgBox ( this g, int idxParameter, Type parameterType ) : void
g	this	This object.
idxParameter	int	Index of the parameter to load on the stack.
parameterType	System.Type	Type of the parameter.
return	void

LdInt32() public static method

Emits the IL to push the integer (emits the best opcode depending on the value: OpCodes.Ldc_I4_0 or OpCodes.Ldc_I4_M1 for instance) value onto the stack.

public static LdInt32 ( this g, int i ) : void
g	this	This object.
i	int	The integer value to push.
return	void

LdLoc() public static method

Emits the IL to push (OpCodes.Ldloc) the given local on top of the stack.

public static LdLoc ( this g, LocalBuilder local ) : void
g	this	This object.
local	System.Reflection.Emit.LocalBuilder	The local variable to push.
return	void

RepushActualParameters() public static method

Emits the optimal IL to push the actual parameter values on the stack (OpCodes.Ldarg_0... OpCodes.Ldarg).

public static RepushActualParameters ( this g, bool startAtArgument0, int count ) : void
g	this	This object.
startAtArgument0	bool	False to skip the very first argument: for a method instance Arg0 is the 'this' object (see ) HasThis and ExplicitThis).
count	int	Number of parameters to push.
return	void

StArg() public static method

Emits the IL to pop (OpCodes.Starg) the top of the stack into the actual argument at the given index.

public static StArg ( this g, int i ) : void
g	this	This object.
i	int	Parameter index (0 being the 'this' for instance method).
return	void

StLoc() public static method

Emits the IL to pop (OpCodes.Stloc) the top of the stack into a local variable.

public static StLoc ( this g, LocalBuilder local ) : void
g	this	This object.
local	System.Reflection.Emit.LocalBuilder	The local variable to pop.
return	void

StoreDefaultValueForOutParameter() public static method

Emits code that sets the parameter (that must be a 'ref' or 'out' parameter) to the default of its type. Handles static or instance methods and value or reference type.

public static StoreDefaultValueForOutParameter ( this g, ParameterInfo byRefParameter ) : void
g	this	This object.
byRefParameter	System.Reflection.ParameterInfo	The 'by ref' parameter.
return	void
