Method Detail

isUnknown

public boolean isUnknown()

Returns true if this type of attribute is unknown. This means that the attribute content can't be parsed to extract constant pool references, labels, etc. Instead, the attribute content is read as an opaque byte array, and written back as is. This can lead to invalid attributes, if the content actually contains constant pool references, labels, or other symbolic references that need to be updated when there are changes to the constant pool, the method bytecode, etc. The default implementation of this method always returns true.

Returns:

true if this type of attribute is unknown.

isCodeAttribute

public boolean isCodeAttribute()

Returns true if this type of attribute is a code attribute.

Returns:

true if this type of attribute is a code attribute.
