Method Detail

value

public short value()

Gets the underlying flags value.

endOfStream

public boolean endOfStream()

Determines whether the END_STREAM flag is set. Only applies to DATA and HEADERS frames.

endOfHeaders

public boolean endOfHeaders()

Determines whether the END_HEADERS flag is set. Only applies for HEADERS, PUSH_PROMISE, and CONTINUATION frames.

priorityPresent

public boolean priorityPresent()

Determines whether the flag is set indicating the presence of the exclusive, stream dependency, and weight fields in a HEADERS frame.

ack

public boolean ack()

Determines whether the flag is set indicating that this frame is an ACK. Only applies for SETTINGS and PING frames.

paddingPresent

public boolean paddingPresent()

For frames that include padding, indicates if the PADDED field is present. Only applies to DATA, HEADERS, PUSH_PROMISE and CONTINUATION frames.

getNumPriorityBytes

public int getNumPriorityBytes()

Gets the number of bytes expected for the priority fields of the payload. This is determined by the priorityPresent() flag.

getPaddingPresenceFieldLength

public int getPaddingPresenceFieldLength()

Gets the length in bytes of the padding presence field expected in the payload. This is determined by the paddingPresent() flag.

endOfStream

public Http2Flags endOfStream(boolean endOfStream)

Sets the END_STREAM flag.

endOfHeaders

public Http2Flags endOfHeaders(boolean endOfHeaders)

Sets the END_HEADERS flag.

priorityPresent

public Http2Flags priorityPresent(boolean priorityPresent)

Sets the PRIORITY flag.

paddingPresent

public Http2Flags paddingPresent(boolean paddingPresent)

Sets the PADDED flag.

ack

public Http2Flags ack(boolean ack)

Sets the ACK flag.

setFlag

public Http2Flags setFlag(boolean on,
                          short mask)

Generic method to set any flag.

Parameters:

on - if the flag should be enabled or disabled.

mask - the mask that identifies the bit for the flag.

Returns:

this instance.

isFlagSet

public boolean isFlagSet(short mask)

Indicates whether or not a particular flag is set.

Parameters:

mask - the mask identifying the bit for the particular flag being tested

Returns:

true if the flag is set

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString
