Constructor Detail

ConstantFloat

public ConstantFloat(ConstantFloat c)

Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.

Parameters:

c - Source to copy.

ConstantFloat

ConstantFloat(java.io.DataInput file)
       throws java.io.IOException

Initialize instance from file data.

Parameters:

file - Input stream.

Throws:

java.io.IOException - if an I/O error occurs.

ConstantFloat

public ConstantFloat(float bytes)

Constructs a ConstantFloat.

Parameters:

bytes - Data.

Method Detail

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(java.io.DataOutputStream file)
          throws java.io.IOException

Dumps constant float to file stream in binary format.

Specified by:

dump in class Constant

Parameters:

file - Output file stream.

Throws:

java.io.IOException - if an I/O error occurs.

getBytes

public float getBytes()

Gets the data.

Returns:

data, that is, 4 bytes.

getConstantValue

public java.lang.Object getConstantValue(ConstantPool cp)

Gets the Float object.

Specified by:

getConstantValue in interface ConstantObject

Parameters:

cp - the constant pool (not used).

Returns:

Float object.

setBytes

public void setBytes(float bytes)

Sets the raw bytes that represent the float value.

Parameters:

bytes - the raw bytes that represent the float value.

toString

public java.lang.String toString()

Overrides:

toString in class Constant

Returns:

String representation.
