Field Details

filePosition

private int filePosition

The position within the file that we will write to next. This is only updated when the buffer is flushed to the outputStream.

tempBuf

private byte[] tempBuf

A temporary buffer that can be used for larger writes. Can be replaced with a larger buffer if needed. Must be at least 8 bytes

zeroBuf

private byte[] zeroBuf

A buffer of 0s to use for writing alignment values

Constructor Details

DexDataWriter

public DexDataWriter(@Nonnull
 OutputStream output,
 int filePosition)
