Constructor Detail

Void

public Void()

Constructs a new null pointer.

Void

public Void(long value)

Constructs a new void pointer that has the given value. Use this method for constructing special constants such as (HWND)-1.

Void

public Void(Pointer.Void that)

Method Detail

getLength

public int getLength()

Description copied from class: Parameter

Returns the length of the parameter in memory. This method is similar to C sizeof() operator.

Specified by:

getLength in class Parameter

write

public void write(DataBuffer stackBuffer,
                  int offset,
                  boolean invokedByCallback)
           throws MemoryAccessViolationException

Description copied from class: Parameter

Writes this parameter to a specified data source.

Specified by:

write in class Parameter

Throws:

MemoryAccessViolationException

read

public void read(DataBuffer stackBuffer,
                 int offset,
                 boolean invokedByCallback)
          throws MemoryAccessViolationException

Description copied from class: Parameter

Reads this parameter from a specified data source.

Specified by:

read in class Parameter

Throws:

MemoryAccessViolationException

clone

public java.lang.Object clone()

Specified by:

clone in class Parameter

setValue

public void setValue(long value)

Sets handle value of this pointer.

Specified by:

setValue in interface IntegerParameter

getValue

public long getValue()

Returns handle value of this object.

Specified by:

getValue in interface IntegerParameter

isNull

public boolean isNull()

Tests if this pointer is null.

Specified by:

isNull in interface PointerParameter

Returns:

true if this pointer is null; false otherwise

getDebugInfo

public java.lang.String getDebugInfo()

Converts this pointer to string representation.

Specified by:

getDebugInfo in class Parameter

Returns:

string "(void*)0x[pointer_value_in_hexadecimal_format]"

asFunction

public Function asFunction()

Converts this poiter to a function.

Since:

1.2

asFunction

public Function asFunction(byte callingConvention)

Converts this poiter to a function.

Parameters:

callingConvention - calling convention.

Since:

1.2

asTypedPointer

public void asTypedPointer(Pointer target)

Deprecated. use castTo(Pointer) method instead

Assigns this pointer value to the typed pointer.

Parameters:

target - void pointer.

castTo

public void castTo(Pointer target)

Casts this pointer to the given typed pointer.

Parameters:

target - the target typed pointer

castTo

public void castTo(Pointer.Void target)

Casts this pointer to the another void pointer.

Parameters:

target - the target void pointer

equals

public boolean equals(java.lang.Object obj)

Description copied from class: Parameter

Compares this Parameter object to a given object. Two Parameter objects are considered equal if their byte representations are equal and they are of the same type. Subclasses may override this method as appropriate.

Overrides:

equals in class Parameter

Parameters:

obj - a value to compare this object to.

Returns:

true if two objects are equal.

hashCode

public int hashCode()

Overrides:

hashCode in class Parameter

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
