Constructor Detail

AbstractFloat

protected AbstractFloat(double val,
                        int length)

Constructs a floating-point object with a specified value and the length equal to its native length in bytes.

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

getValue

public double getValue()

Description copied from interface: FloatParameter

Returns a floating-point value of the object instance.

Specified by:

getValue in interface FloatParameter

convertToDouble

protected abstract double convertToDouble(byte[] bytes)

Converts native representation of a floating-point value to Java double value.

convertToBytes

protected abstract byte[] convertToBytes(double d)

Converts Java double value to its native representation.

setValue

public void setValue(double d)

Description copied from interface: FloatParameter

Sets a floating-point value to a specified value.

Specified by:

setValue in interface FloatParameter

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

toString

public java.lang.String toString()
