Parameters:
string_index - Index of Constant_Utf8 in constant pool
Method Detail

accept

public void accept(Visitor v)
Called by objects that are traversing the nodes of the tree implicitely 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 final void dump(DataOutputStream file)
                throws IOException
Dump constant field reference to file stream in binary format.

Specified by:
dump in class Constant
Parameters:
file - Output file stream
Throws:
IOException

getStringIndex

public final int getStringIndex()
Returns:
Index in constant pool of the string (ConstantUtf8).

setStringIndex

public final void setStringIndex(int string_index)
Parameters:
string_index - the index into the constant of the string value

toString

public final String toString()
Overrides:
toString in class Constant
Returns:
String representation.

getConstantValue

public Object getConstantValue(ConstantPool cp)
Specified by:
getConstantValue in interface ConstantObject
Returns:
String object

getBytes

public String getBytes(ConstantPool cp)
Returns:
dereferenced string
