Class GzipInflatingBuffer.GzipMetadataReader

java.lang.Object

io.grpc.internal.GzipInflatingBuffer.GzipMetadataReader

Enclosing class:

GzipInflatingBuffer

private class GzipInflatingBuffer.GzipMetadataReader
extends Object

Reads gzip header and trailer bytes from the inflater's buffer (if bytes beyond the inflate block were given to the inflater) and then from gzippedData, and handles updating the CRC and the count of gzipped bytes consumed.

Method Details

readUnsignedByte

private int readUnsignedByte()

Returns the next unsigned byte, adding it the CRC and incrementing bytesConsumed.

It is the responsibility of the caller to verify and reset the CRC as needed, as well as caching the current CRC value when necessary before invoking this method.

skipBytes

private void skipBytes(int length)

Skips length bytes, adding them to the CRC and adding length to bytesConsumed.

It is the responsibility of the caller to verify and reset the CRC as needed, as well as caching the current CRC value when necessary before invoking this method.

readableBytes

private int readableBytes()

readBytesUntilZero

private boolean readBytesUntilZero()

Skip over a zero-terminated byte sequence. Returns true when the zero byte is read.

readUnsignedShort

private int readUnsignedShort()

Reads unsigned short in Little-Endian byte order.

readUnsignedInt

private long readUnsignedInt()

Reads unsigned integer in Little-Endian byte order.
