Constructor Detail

MethodMetadata

public MethodMetadata(int methodID,
                      ScopedLocalVariable[] lvt,
                      int[] lnt)

Creates a new MethodMetadata instance.

Parameters:

methodID - the Method the metadata is for

lnt - 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

lvt - the table describing the symbolic information for the local variables in the method

Method Detail

getLineNumberTable

public 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
