methods. |
| Field(Field c) Initialize from another object. |
(package private) | Field(DataInputStream file, ConstantPool constant_pool) Construct object from file stream. |
| Field(int access_flags, int name_index, int signature_index, Attribute[] attributes, ConstantPool constant_pool) |
Field
public Field()
- Empty constructor, all attributes have to be defined via `setXXX'
methods. Use at your own risk.
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
Field(DataInputStream file, ConstantPool constant_pool)
throws java.io.IOException,
java.lang.ClassFormatError
- Construct object from file stream.
- Parameters:
- file - Input stream
- throw IOException, ClassFormatError
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
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
dump
public final void dump(DataOutputStream file)
throws java.io.IOException
- Dump field to file stream on binary format.
- Parameters:
- file - Output file stream
- throw IOException
getAccessFlags

- Returns: Access flags of the class field.
getAttributes
public final Attribute[] getAttributes()
- Returns: Collection of field attributes.
getConstantPool
public final ConstantPool getConstantPool()
- Returns: Constant pool used by this object.
- See Also:
- ConstantPool
getConstantValue
public final ConstantValue getConstantValue()
- Returns: constant value associated with this field (may be null)
getName
public final String getName()
- Returns: Name of field
getNameIndex
public final int getNameIndex()
- Returns: Index in constant pool of field name.
getSignature
public final String getSignature()
- Returns: String representation of field type signature (java style)
getSignatureIndex
public final int getSignatureIndex()
- Returns: Index in constant pool of field signature.
setAccessFlags
public final void setAccessFlags(int access_flags)
- Parameters:
- access_flags.
setAttributes
public final void setAttributes(Attribute[] attributes)
- Parameters:
- attributes.
setConstantPool
public final void setConstantPool(ConstantPool constant_pool)
- Parameters:
- constant_pool - Constant pool to be used for this object.
- See Also:
- ConstantPool
setNameIndex
public final void setNameIndex(int name_index)
- Parameters:
- name_index.
setSignatureIndex
public final void setSignatureIndex(int signature_index)
- Parameters:
- signature_index.
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.
- throw InternalError
