Dump constant integer to file stream in binary format.

Specified by:

dump in class Constant

Parameters:

file - Output file stream

Throws:

IOException

getBytes

public final int getBytes()

Returns:

data, i.e., 4 bytes.

setBytes

public final void setBytes(int bytes)

Parameters:

bytes - the raw bytes that represent this integer

toString

Overrides:

toString in class Constant

Returns:

String representation.

getConstantValue

public Object getConstantValue(ConstantPool cp)

Specified by:

getConstantValue in interface ConstantObject

Returns:

Integer object
