Overrides:
accept in interface Constant
Parameters:
v - Visitor object

dump

public final void dump(DataOutputStream file)
            throws IOException
Dump name and signature index to file stream in binary format.
Overrides:
dump in interface Constant
Parameters:
file - Output file stream

getName

public final String getName(ConstantPool cp)
Returns:
name

getNameIndex

public final int getNameIndex()
Returns:
Name index in constant pool of field/method name.

getSignature

public final String getSignature(ConstantPool cp)
Returns:
signature

getSignatureIndex

Returns:
Index in constant pool of field/method signature.

setNameIndex

public final void setNameIndex(int name_index)
Parameters:
name_index - the name index of this constant

setSignatureIndex

public final void setSignatureIndex(int signature_index)
Parameters:
signature_index - the signature index in the constant pool of this type
