Constructor Detail

Field

public Field(Field c)
Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.


Field

public Field(int access_flags,
             int name_index,
             int signature_index,
             Attribute[] attributes,
             ConstantPool constant_pool)
Parameters:
access_flags - Access rights of field
name_index - Points to field name in constant pool
signature_index - Points to encoded signature
attributes - Collection of attributes
constant_pool - Array of constants
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.

Parameters:
v - Visitor object

getConstantValue

public final ConstantValue getConstantValue()
Returns:
constant value associated with this field (may be null)

toString

public final String toString()
Return string representation close to declaration format, `public static final short MAX = 100', e.g..

Returns:
String representation of field, including the signature.

copy

public final Field copy(ConstantPool _constant_pool)
Returns:
deep copy of this field

getType

public Type getType()
Returns:
type of field

getComparator

public static BCELComparator getComparator()
Returns:
Comparison strategy object

setComparator

public static void setComparator(BCELComparator comparator)
Parameters:
comparator - Comparison strategy object

equals

public boolean equals(Object obj)
Return value as defined by given BCELComparator strategy. By default two Field objects are said to be equal when their names and signatures are equal.

See Also:
Object.equals(java.lang.Object)

hashCode

public int hashCode()
Return value as defined by given BCELComparator strategy. By default return the hashcode of the field's name XOR signature.

See Also:
Object.hashCode()
