Usage

From source file:com.facebook.buck.android.resources.ResourceTable.java

public static ResourceTable get(ByteBuffer buf) {
    int type = buf.getShort();
    int headerSize = buf.getShort();
    int chunkSize = buf.getInt();
    int packageCount = buf.getInt();

    Preconditions.checkState(type == CHUNK_RESOURCE_TABLE);
    Preconditions.checkState(headerSize == HEADER_SIZE);
    Preconditions.checkState(packageCount == 1);

    StringPool strings = StringPool.get(slice(buf, buf.position()));
    ResTablePackage resPackage = ResTablePackage.get(slice(buf, HEADER_SIZE + strings.getChunkSize()));

    Preconditions.checkState(chunkSize == HEADER_SIZE + strings.getChunkSize() + resPackage.getChunkSize());

    return new ResourceTable(strings, resPackage);
