Constructor Detail

ConstantArgument

public ConstantArgument(Constant constant)

This constructor assumes a constant pool index width of two bytes, which is the norm for most opcodes.

Parameters:

constant - Constant object whose constant pool index will comprise the data of this instruction argument.

ConstantArgument

public ConstantArgument(Constant constant,
                        int width)

Constructor.

Parameters:

constant - Constant object whose constant pool index will comprise the data of this instruction argument.

width - Width of this argument's data, in bytes.

Method Detail

write

public void write(java.io.DataOutput out)
           throws java.io.IOException

This method writes this argument's data to the specified output stream. The argument's data is simply the constant pool index of the constant, written as a numeric value of the appropriate width.

Specified by:

write in interface WritableData

Parameters:

out - Data output stream to which to write argument data.

Throws:

java.io.IOException - if any error occurs while writing.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
