ExceptionTable

• java.lang.Object
  • com.sun.org.apache.bcel.internal.classfile.Attribute

Fields Summary
private int	number_of_exceptions
private int[]	exception_index_table

Constructors Summary
public ExceptionTable(ExceptionTable c) Initialize from another object. Note that both objects use the same references (shallow copy). Use copy() for a physical copy. this(c.getNameIndex(), c.getLength(), c.getExceptionIndexTable(), c.getConstantPool());
public ExceptionTable(int name_index, int length, int[] exception_index_table, ConstantPool constant_pool) param name_index Index in constant pool param length Content length in bytes param exception_index_table Table of indices in constant pool param constant_pool Array of constants super(Constants.ATTR_EXCEPTIONS, name_index, length, constant_pool); setExceptionIndexTable(exception_index_table);
ExceptionTable(int name_index, int length, DataInputStream file, ConstantPool constant_pool) Construct object from file stream. param name_index Index in constant pool param length Content length in bytes param file Input stream param constant_pool Array of constants throw IOException this(name_index, length, (int[])null, constant_pool); number_of_exceptions = file.readUnsignedShort(); exception_index_table = new int[number_of_exceptions]; for(int i=0; i < number_of_exceptions; i++) exception_index_table[i] = file.readUnsignedShort();

Methods Summary
public void	accept(com.sun.org.apache.bcel.internal.classfile.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. param v Visitor object v.visitExceptionTable(this);
public com.sun.org.apache.bcel.internal.classfile.Attribute	copy(com.sun.org.apache.bcel.internal.classfile.ConstantPool constant_pool) return deep copy of this attribute ExceptionTable c = (ExceptionTable)clone(); c.exception_index_table = (int[])exception_index_table.clone(); c.constant_pool = constant_pool; return c;
public final void	dump(java.io.DataOutputStream file) Dump exceptions attribute to file stream in binary format. param file Output file stream throw IOException super.dump(file); file.writeShort(number_of_exceptions); for(int i=0; i < number_of_exceptions; i++) file.writeShort(exception_index_table[i]);
public final int[]	getExceptionIndexTable() return Array of indices into constant pool of thrown exceptions. return exception_index_table;
public final java.lang.String[]	getExceptionNames() return class names of thrown exceptions String[] names = new String[number_of_exceptions]; for(int i=0; i < number_of_exceptions; i++) names[i] = constant_pool.getConstantString(exception_index_table[i], Constants.CONSTANT_Class). replace('/", '."); return names;
public final int	getNumberOfExceptions() return Length of exception table. return number_of_exceptions;
public final void	setExceptionIndexTable(int[] exception_index_table) param exception_index_table. Also redefines number_of_exceptions according to table length. this.exception_index_table = exception_index_table; number_of_exceptions = (exception_index_table == null)? 0 : exception_index_table.length;
public final java.lang.String	toString() return String representation, i.e., a list of thrown exceptions. StringBuffer buf = new StringBuffer(""); String str; for(int i=0; i < number_of_exceptions; i++) { str = constant_pool.getConstantString(exception_index_table[i], Constants.CONSTANT_Class); buf.append(Utility.compactClassName(str, false)); if(i < number_of_exceptions - 1) buf.append(", "); } return buf.toString();
