ConstantValue
public ConstantValue(ConstantValue c)
- Initialize from another object. Note that both objects use the same
references (shallow copy). Use clone() for a physical copy.
ConstantValue
public ConstantValue(int name_index,
int length,
int constantvalue_index,
ConstantPool constant_pool)
- Parameters:
name_index
- Name index in constant pool
length
- Content length in bytes
constantvalue_index
- Index in constant pool
constant_pool
- Array of constants
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.
- Parameters:
v
- Visitor object- Overrides:
- accept in class Attribute
dump
public final void dump(java.io.DataOutputStream file)
throws java.io.IOException
- Dump constant value attribute to file stream on binary format.
- Parameters:
file
- Output file stream- Overrides:
- dump in class Attribute
getConstantValueIndex
public final int getConstantValueIndex()
- Returns:
- Index in constant pool of constant value.
setConstantValueIndex
public final void setConstantValueIndex(int constantvalue_index)
- Parameters:
constantvalue_index.
-
toString
public final java.lang.String toString()
throws java.lang.InternalError
- Returns:
- String representation of constant value.
- Overrides:
- toString in class Attribute
copy
public Attribute copy(ConstantPool constant_pool)
- Returns:
- deep copy of this attribute
- Overrides:
- copy in class Attribute
