Class ResChunk

java.lang.Object

com.facebook.buck.android.resources.ResChunk

Direct Known Subclasses:

ResourcesXml, ResourceTable, ResTablePackage, ResTableType, ResTableTypeSpec, StringPool

public abstract class ResChunk
extends Object

ResChunk is the base of most structures in Android's .arsc and compiled .xml files. It consists of: u16 chunkType u16 headerSize u32 chunkSize

Some common types used by different chunks:

StringRef is a u32 string id ResRef is a u32 resource id ResValue is a chunk of: u16 size u8 0x00 u8 dataType (one of ResChunk.RES_XXXXXXX) u32 data

Method Detail

getType

public final int getType()

getHeaderSize

public final int getHeaderSize()

getChunkSize

public final int getChunkSize()

getTotalSize

public int getTotalSize()

For most chunk's totalSize == chunkSize. For some types, the type logically consists of multiple chunks. In these cases, totalSize is the sum of all the chunks. This is the full size written/read from a buffer for get/put.

serialize

public final byte[] serialize()

put

public abstract void put(ByteBuffer output)

wrap

public static ByteBuffer wrap(byte[] data)

slice

public static ByteBuffer slice(ByteBuffer map,
                               int offset)

slice

public static ByteBuffer slice(ByteBuffer map,
                               int offset,
                               int length)
