LineNumberTableAttribute_info

• java.lang.Object
  • Attribute_info

LineNumberTable_attribute {
u2 attribute_name_index;
u4 attribute_length;
u2 line_number_table_length;
{ u2 start_pc;
u2 line_number;
} line_number_table[line_number_table_length];
}

LineNumberTable_attribute structure contains the following items:
line_number_table_length

The value of the line_number_table_length item indicates the number of
entries in the line_number_table array.
line_number_table[]

Each entry in the line_number_table array indicates that the line number
in the original source file changes at a given point in the code array.


Each line_number_table entry must contain the following two items:
start_pc

The value of the start_pc item must indicate the index into the code array
at which the code for a new line in the original source file begins. The
value of start_pc must be less than the value of the code_length item of
the {@link CodeAttribute_info} attribute of which this LineNumberTable
is an attribute.

line_number

The value of the line_number item must give the corresponding line number
in the original source file.

public LineNumber_info	get(int offset) Returns {@link LineNumber_info} descriptor at a given offset. param offset line number entry offset [must be in [0, size()) range; input not checked] return LineNumber_info descriptor [never null] throws IndexOutOfBoundsException if 'offset' is outside of valid range return (LineNumber_info) m_lines.get (offset);
public long	length() return 8 + (m_lines.size () << 2); // use size() if class becomes non-final
public int	size() Returns the number of descriptors in this collection [can be 0]. return m_lines.size ();
