Constructor Details

ModulePackages

public ModulePackages(int nameIndex,
 int length,
 int[] packageIndexTable,
 ConstantPool constantPool)

Parameters:

nameIndex - Index in constant pool

length - Content length in bytes

packageIndexTable - Table of indices in constant pool

constantPool - Array of constants

ModulePackages

public ModulePackages(ModulePackages c)

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

Parameters:

c - Source to copy.

Method Details

accept

public void accept(Visitor v)

Called by objects that are traversing the nodes of the tree implicitly defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

Specified by:

accept in interface Node

Specified by:

accept in class Attribute

Parameters:

v - Visitor object

copy

public Attribute copy(ConstantPool constantPool)

Specified by:

copy in class Attribute

Parameters:

constantPool - constant pool to save.

Returns:

deep copy of this attribute

dump

public void dump(DataOutputStream file)
          throws IOException

Dump ModulePackages attribute to file stream in binary format.

Overrides:

dump in class Attribute

Parameters:

file - Output file stream

Throws:

IOException - if an I/O error occurs.

getNumberOfPackages

public int getNumberOfPackages()

Returns:

Length of package table.

getPackageIndexTable

public int[] getPackageIndexTable()

Returns:

array of indices into constant pool of package names.

getPackageNames

public String[] getPackageNames()

Returns:

string array of package names

setPackageIndexTable

public void setPackageIndexTable(int[] packageIndexTable)

Parameters:

packageIndexTable - the list of package indexes Also redefines number_of_packages according to table length.

toString

public String toString()

Overrides:

toString in class Attribute

Returns:

String representation, i.e., a list of packages.
