Method Detail

getEntryClass

public java.lang.Class getEntryClass()

Returns a class of array items.

getLength

public int getLength()

Returns the length of the array data in bytes.

Specified by:

getLength in class Parameter

getBytes

public byte[] getBytes()

Returns byte data of an array.

clone

public java.lang.Object clone()

Specified by:

clone in class Parameter

getDebugInfo

public java.lang.String getDebugInfo()

Description copied from class: Parameter

Return debug info for JNIWrapper parameter.

Specified by:

getDebugInfo in class Parameter

Returns:

debug info

getElement

public Parameter getElement(int i)

Description copied from interface: ArrayParameter

Returns an array item specified by an index.

Specified by:

getElement in interface ArrayParameter

Parameters:

i - index of a requested array item

setElement

public void setElement(int i,
                       Parameter elem)

Description copied from interface: ArrayParameter

Replaces an array item with the specified object.

Specified by:

setElement in interface ArrayParameter

Parameters:

i - index of an item to be replaced

elem - object to be set as array item

getElementCount

public int getElementCount()

Description copied from interface: ArrayParameter

Returns the number of elements in the array.

Specified by:

getElementCount in interface ArrayParameter

toParameterArray

public Parameter[] toParameterArray()

Description copied from interface: ArrayParameter

Returns items as Java array.

Specified by:

toParameterArray in interface ArrayParameter

fromParameterArray

public void fromParameterArray(Parameter[] params)

Description copied from interface: ArrayParameter

Sets array contents to the given values.

Specified by:

fromParameterArray in interface ArrayParameter

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

readPartially

public void readPartially(byte[] arr,
                          int offset)

Reads raw data from a given array into this object's data source. This is equal to a read(byte[] arr, int offset), where data beyond a given array length in the source array is unspecified.

resizeAndRead

public void resizeAndRead(byte[] arr,
                          int offset,
                          int dataLength)

Sets a new size of this array and reads it from a given byte array.

Parameters:

arr - new array raw (as in memory) content.

offset - where this parameter starts in arr

dataLength - raw length of this array (sizeof(element) * elementCount)

forceElementCount

public void forceElementCount(int elementCount)

Description copied from interface: ArrayParameter

Sets a new array size without memory reallocation. This method should be used with caution as the array may access invalid memory area if an incorrect value is passed in the argument.

Specified by:

forceElementCount in interface ArrayParameter

setElementCount

public void setElementCount(int elementCount)

Description copied from interface: ArrayParameter

Resizes this array to a given size.

Specified by:

setElementCount in interface ArrayParameter

getAlignedLength

protected int getAlignedLength()

Description copied from class: Parameter

Returns a parameter length in bytes aligned to default alignment.

Overrides:

getAlignedLength in class Parameter

getAlignmentRequirement

public int getAlignmentRequirement()

Overrides:

getAlignmentRequirement in class Parameter

Returns:

required alignment within a structure or an array

asReturnValue

protected Parameter asReturnValue()

Description copied from class: Parameter

Returns a parameter that represents this one as a return value. Implementors may use this as a convenience shortcut for users when implementing such objects as strings or arrays to allow users to specify an object as a return value instead of requiring a pointer to it. For general use the default implementation should suffice.

Overrides:

asReturnValue in class Parameter

Returns:

this

getFirstMemberSize

public int getFirstMemberSize()

Description copied from interface: AlignmentAwareParameter

Should return first member size. If first member is structure, should return it's first parameter (in recursive manner). Unions should return their full size.

Specified by:

getFirstMemberSize in interface AlignmentAwareParameter

Returns:

first structure member size
