Constructs a ConstantLong.

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

Specified by:

dump in class Constant

Parameters:

file - Output file stream.

Throws:

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

getBytes

public long getBytes()

Gets the data.

Returns:

data, that is, 8 bytes.

getConstantValue

public java.lang.Object getConstantValue(ConstantPool cp)

Gets the Long object.

Specified by:

getConstantValue in interface ConstantObject

Parameters:

cp - the constant pool (not used).

Returns:

Long object.

setBytes

public void setBytes(long bytes)

Sets the raw bytes that represent the long value.

Parameters:

bytes - the raw bytes that represent the long value.

toString
