Class MethodMetadata

    java.lang.Object
      com.sun.squawk.MethodMetadata

Direct Known Subclasses:
  FullMethodMetadata

    public class MethodMetadata

extends Object

A `MethodMetadata` instance represents all the information about a method body that is not absolutely required for execution. This includes the information found in the JVM LineNumberTable class file attributes.

Method Summary
`static int` | `binarySearch(MethodMetadata[] a, int keyOffset)` Search through the array of MethodMetadata looking for the metadata for the method with vtable/stable index keyOffset.
`int[]` | `getLineNumberTable()` Gets the table mapping instruction addresses to the source line numbers that start at the addresses.
`ScopedLocalVariable[]` | `getLocalVariableTable()` Gets a table describing the scope, name and type of each local variable in the method.

Method Detail

### getLineNumberTable

    public final int[] getLineNumberTable()

  Gets the table mapping instruction addresses to the source line numbers that start at the addresses. The table is encoded as an int array where the high 16-bits of each element is an instruction address and the low 16-bits is the corresponding source line.

  Returns:
    the line number table or null if there is no line number information for the method

### getLocalVariableTable

    public ScopedLocalVariable[] getLocalVariableTable()

  Gets a table describing the scope, name and type of each local variable in the method.

  Returns:
    the local variable table or null if there is no local variable information for the method

### binarySearch

    public static int binarySearch(MethodMetadata[] a,
                                   int keyOffset)

  Search through the array of MethodMetadata looking for the metadata for the method with vtable/stable index keyOffset.

  Parameters:
    `a` - array of metadata
    `keyOffset` - the offset of the method in the static/virtual method table.
  Returns:
    the index into the MethodMetadata array, or -1 if not found.
