Examples with Attribute com.android.dx.cf.iface.Attribute used on opensource projects

Example 6 with Attribute

use of com.android.dx.cf.iface.Attribute in project J2ME-Loader by nikita36078.

the class AttributeFactory method parse0.

/**
 * Parses attribute content. The base class implements this by constructing
 * an instance of {@link RawAttribute}. Subclasses are expected to
 * override this to do something better in most cases.
 *
 * @param cf {@code non-null;} class file to parse from
 * @param context context to parse in; one of the {@code CTX_*}
 * constants
 * @param name {@code non-null;} the attribute name
 * @param offset offset into {@code bytes} to start parsing at; this
 * is the offset to the start of attribute data, not to the header
 * @param length the length of the attribute data
 * @param observer {@code null-ok;} parse observer to report to, if any
 * @return {@code non-null;} an appropriately-constructed {@link Attribute}
