EncodedMethod

public final class EncodedMethod extends EncodedMember implements Comparable
Class that representats a method of a class.

Fields Summary
private final com.android.dexgen.rop.cst.CstMethodRef
method
{@code non-null;} constant for the method
private final CodeItem
code
{@code null-ok;} code for the method, if the method is neither {@code abstract} nor {@code native}
Constructors Summary
public EncodedMethod(com.android.dexgen.rop.cst.CstMethodRef method, int accessFlags, com.android.dexgen.dex.code.DalvCode code, com.android.dexgen.rop.type.TypeList throwsList)
Constructs an instance.

param
method {@code non-null;} constant for the method
param
accessFlags access flags
param
code {@code null-ok;} code for the method, if it is neither {@code abstract} nor {@code native}
param
throwsList {@code non-null;} list of possibly-thrown exceptions, just used in generating debugging output (listings)

Methods Summary
public voidaddContents(DexFile file)
{@inheritDoc}
