Constructor Detail

FieldOrMethodback to summary
pack-priv FieldOrMethod()
FieldOrMethodback to summary
protected FieldOrMethod(final DataInput file, final ConstantPool constantPool) throws IOException

Constructs object from file stream.

Parameters
file:DataInput

Input stream

Exceptions
IOException:
if an I/O error occurs.
FieldOrMethodback to summary
protected FieldOrMethod(final DataInputStream file, final ConstantPool constantPool) throws IOException

Deprecated

(6.0) Use FieldOrMethod(java.io.DataInput, ConstantPool) instead.

Constructs object from file stream.

Parameters
file:DataInputStream

Input stream

Annotations
@Deprecated
Exceptions
IOException:
if an I/O error occurs.
FieldOrMethodback to summary
protected FieldOrMethod(final FieldOrMethod c)

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

Parameters
c:FieldOrMethod

Source to copy.

FieldOrMethodback to summary
protected FieldOrMethod(final int accessFlags, final int nameIndex, final int signatureIndex, final Attribute[] attributes, final ConstantPool constantPool)
Parameters
accessFlags:int

Access rights of method

nameIndex:int

Points to field name in constant pool

signatureIndex:int

Points to encoded signature

attributes:Attribute[]

Collection of attributes

constantPool:ConstantPool

Array of constants

Method Detail

copy_back to summary
protected FieldOrMethod copy_(final ConstantPool constantPool)
Returns:FieldOrMethod

deep copy of this field

dumpback to summary
public final void dump(final DataOutputStream file) throws IOException

Dump object to file stream on binary format.

Parameters
file:DataOutputStream

Output file stream

Exceptions
IOException:
if an I/O error occurs.
getAnnotationEntriesback to summary
public AnnotationEntry[] getAnnotationEntries()
Returns:AnnotationEntry[]

Annotations on the field or method

Since
6.0
getAttributeback to summary
public final <T extends Attribute> T getAttribute(final byte tag)

Gets attribute for given tag.

Returns:T

Attribute for given tag, null if not found. Refer to com.sun.org.apache.bcel.internal.Const#ATTR_UNKNOWN constants named ATTR_* for possible values.

Annotations
@SuppressWarnings:unchecked
Since
6.10.0
getAttributesback to summary
public final Attribute[] getAttributes()
Returns:Attribute[]

Collection of object attributes.

getConstantPoolback to summary
public final ConstantPool getConstantPool()
Returns:ConstantPool

Constant pool used by this object.

getGenericSignatureback to summary
public final String getGenericSignature()

Hunts for a signature attribute on the member and returns its contents. So where the 'regular' signature may be (Ljava/util/Vector;)V the signature attribute may in fact say 'Ljava/lang/Vector<Ljava/lang/String>;' Coded for performance - searches for the attribute only when requested - only searches for it once.

Since
6.0
