Constructor Details

FieldOrMethod

protected FieldOrMethod(FieldOrMethod c)

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

FieldOrMethod

protected FieldOrMethod(DataInputStream file,
 ConstantPool constant_pool)
                 throws IOException,
ClassFormatException

Construct object from file stream.

Parameters:

file - Input stream

Throws:

IOException

ClassFormatException

FieldOrMethod

protected FieldOrMethod(int access_flags,
 int name_index,
 int signature_index,
 Attribute[] attributes,
 ConstantPool constant_pool)

Parameters:

access_flags - Access rights of method

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 Details

dump

public final void dump(DataOutputStream file)
                throws IOException

Dump object to file stream on binary format.

Parameters:

file - Output file stream

Throws:

IOException

getAttributes

public final Attribute[] getAttributes()

Returns:

Collection of object attributes.

setAttributes

public final void setAttributes(Attribute[] attributes)

Parameters:

attributes - Collection of object attributes.

getConstantPool

public final ConstantPool getConstantPool()

Returns:

Constant pool used by this object.

setConstantPool

public final void setConstantPool(ConstantPool constant_pool)

Parameters:

constant_pool - Constant pool to be used for this object.

getNameIndex

public final int getNameIndex()

Returns:

Index in constant pool of object's name.

setNameIndex

public final void setNameIndex(int name_index)

Parameters:

name_index - Index in constant pool of object's name.

getSignatureIndex

public final int getSignatureIndex()

Returns:

Index in constant pool of field signature.

setSignatureIndex

public final void setSignatureIndex(int signature_index)

Parameters:

signature_index - Index in constant pool of field signature.

getName

public final String getName()

Returns:

Name of object, i.e., method name or field name

getSignature

public final String getSignature()

Returns:

String representation of object's type signature (java style)

copy_

protected FieldOrMethod copy_(ConstantPool _constant_pool)

Returns:

deep copy of this field

getAnnotationEntries

public AnnotationEntry[] getAnnotationEntries()

addAnnotationEntry

public void addAnnotationEntry(AnnotationEntry a)

getGenericSignature

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/Vectorinvalid input: '<'Ljava/lang/String>;' Coded for performance - searches for the attribute only when requested - only searches for it once.
