c - Source to copy.

ConstantDouble

ConstantDouble(DataInput file)
        throws IOException

Initialize instance from file data.

Parameters:

file - Input stream

IOException - if an I/O error occurs.

ConstantDouble

public ConstantDouble(double bytes)

Parameters:

bytes - Data

Method Details

accept

public void accept(Visitor v)

Called by objects that are traversing the nodes of the tree implicitly defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

Specified by:

accept in interface Node

Specified by:

accept in class Constant

Parameters:

v - Visitor object

dump

public void dump(DataOutputStream file)
          throws IOException

Dump constant double to file stream in binary format.

Specified by:

dump in class Constant

Parameters:

file - Output file stream

Throws:

IOException - if an I/O error occurs.

getBytes

public double getBytes()

Returns:

data, i.e., 8 bytes.

getConstantValue

public Object getConstantValue(ConstantPool cp)

Description copied from interface: ConstantObject

Gets the object representing the constant, e.g., Long for ConstantLong.

Specified by:

getConstantValue in interface ConstantObject

Parameters:

cp - the constant.

Returns:

Double object

setBytes

public void setBytes(double bytes)

Parameters:

bytes - the raw bytes that represent the double value

toString

public String toString()

Overrides:

toString in class Constant

Returns:

String representation.
