Constructor Details

HpackDecoder

public HpackDecoder(int maxHeaderSize,
 LongSupplier beginNanoTimeSupplier)

Parameters:

maxHeaderSize - The maximum allowed size of a decoded headers block, expressed as total of all name and value bytes, plus 32 bytes per field

beginNanoTimeSupplier - The supplier of a nano timestamp taken at the time the first byte was read

Method Details

getHpackContext

public HpackContext getHpackContext()

getMaxTableCapacity

public int getMaxTableCapacity()

setMaxTableCapacity

public void setMaxTableCapacity(int maxTableCapacity)

Sets the limit for the capacity of the dynamic header table.

This value acts as a limit for the values received from the remote peer via the HPACK dynamic table size update instruction.

After calling this method, a SETTINGS frame must be sent to the other peer, containing the SETTINGS_HEADER_TABLE_SIZE setting with the value passed as argument to this method.

Parameters:

maxTableCapacity - the limit for capacity of the dynamic header table

setLocalMaxDynamicTableSize

@Deprecated
public void setLocalMaxDynamicTableSize(int maxTableSizeLimit)

Deprecated.

use setMaxTableCapacity(int) instead

Parameters:

maxTableSizeLimit - the local dynamic table max size

getMaxHeaderListSize

public int getMaxHeaderListSize()

setMaxHeaderListSize

public void setMaxHeaderListSize(int maxHeaderListSize)

decode

public MetaData decode(ByteBuffer buffer)
                throws HpackException.SessionException,
HpackException.StreamException

Throws:

HpackException.SessionException

HpackException.StreamException

toISO88591String

public static String toISO88591String(ByteBuffer buffer,
 int length)
