ModuleMainClassback to summary
pack-priv ModuleMainClass(final int nameIndex, final int length, final DataInput input, final ConstantPool constantPool) throws IOException

Constructs object from input stream.

Parameters
nameIndex:int

Index in constant pool

length:int

Content length in bytes

input:DataInput

Input stream

constantPool:ConstantPool

Array of constants

Exceptions
IOException:
if an I/O error occurs.

public ModuleMainClass(final int nameIndex, final int length, final int mainClassIndex, final ConstantPool constantPool)
Parameters
nameIndex:int

Index in constant pool

length:int

Content length in bytes

mainClassIndex:int

Host class index

constantPool:ConstantPool

Array of constants

ModuleMainClassback to summary
public ModuleMainClass(final ModuleMainClass c)

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

Parameters
c:ModuleMainClass

Source to copy.

Method Detail

acceptback to summary
public void accept(final Visitor v)

Implements abstract com.sun.org.apache.bcel.internal.classfile.Attribute.accept.

Implements com.sun.org.apache.bcel.internal.classfile.Node.accept.

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.

Parameters
v:Visitor

Visitor object

getHostClassIndexback to summary
public int getHostClassIndex()
Returns:int

public void setHostClassIndex(final int mainClassIndex)
Parameters
mainClassIndex:int

the host class index

toStringback to summary
public String toString()

Overrides com.sun.org.apache.bcel.internal.classfile.Attribute.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

Returns:String

String representation
