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

Example 6 with Attribute

use of com.taobao.android.dx.cf.iface.Attribute in project atlas by alibaba.

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}
     */

Example 7 with Attribute
