Method Detail

fromBytes

public static org.objectweb.asm.tree.ClassNode fromBytes(byte[] bytes)

Read a class from a byte array.
This will use the ClassReader.EXPAND_FRAMES flag.

Parameters:

bytes - The bytecode of the class

Returns:

The class node

fromBytes

public static org.objectweb.asm.tree.ClassNode fromBytes(byte[] bytes,
                                                         int flags)

Read a class from a byte array.

Parameters:

bytes - The bytecode of the class

flags - The flags to use for reading the class

Returns:

The class node

toBytes

public static byte[] toBytes(org.objectweb.asm.tree.ClassNode node,
                             ClassInfoProvider classInfoProvider)

Write a class to a byte array.
The classInfoProvider is used for stack map frame calculation.

Parameters:

node - The class node

classInfoProvider - The class info provider

Returns:

The bytecode of the class

toBytes

public static byte[] toBytes(org.objectweb.asm.tree.ClassNode node,
                             int flags,
                             ClassInfoProvider classInfoProvider)

Write a class to a byte array.
The classInfoProvider is used for stack map frame calculation, if enabled.

Parameters:

node - The class node

flags - The flags to use for writing the class

classInfoProvider - The class info provider

Returns:

The bytecode of the class

toStacklessBytes

public static byte[] toStacklessBytes(org.objectweb.asm.tree.ClassNode node)

Write a class to a byte array without computing the stack map frames.
This will use the ClassWriter.COMPUTE_MAXS flag.

Parameters:

node - The class node

Returns:

The bytecode of the class

toStacklessBytes

public static byte[] toStacklessBytes(org.objectweb.asm.tree.ClassNode node,
                                      int flags)

Write a class to a byte array without computing the stack map frames.

Parameters:

node - The class node

flags - The flags to use for writing the class

Returns:

The bytecode of the class
