Functions ¶
func DecodeNNIBlock ¶
DecodeNNIBlock decodes a non-negative integer value from a block.
func DecodeTypeLength ¶
DecodeTypeLength decodes the TLV type, TLV length, and total size of the block from a byte slice.
func DecodeVarNum ¶
DecodeVarNum decodes a non-negative integer value from a wire value.
func EncodeVarNum ¶
EncodeVarNum encodes a non-negative integer value for encoding.
func GetNNIBlockSize ¶
GetNNIBlockSize returns the size that a non-negative integer block will take when encoded.
func IsCritical ¶
IsCritical returns whether a TLV type is critical.
Types ¶
type Block ¶
type Block struct {
// contains filtered or unexported fields
}
Block contains an encoded block.
func DecodeBlock ¶
DecodeBlock decodes a block from the wire.
func EncodeNNIBlock ¶
EncodeNNIBlock encodes a non-negative integer value in a block of the specified type.
func NewEmptyBlock ¶
NewEmptyBlock creates an empty encoded block.
func (*Block) Append ¶
Append appends a subelement onto the end of the block's value. this adds a subelement, but then also erases the wire. I assume this is because of the recursive nature of b.wire? Probably a big contributor to runtime.
func (*Block) Erase ¶
Erase erases the first subelement of the specified type and returns whether an element was removed.
func (*Block) EraseAll ¶
EraseAll erases all subelements of the specified type and returns the count of elements removed.
func (*Block) Find ¶
Find returns the first subelement of the specified type, or nil if none exists.
func (*Block) Insert ¶
Insert inserts the subelement in order of ascending TLV type, after any subelements of the same TLV type. Note that this assumes subelements are ordered by increasing TLV type. wonder if insert is even necessary at all
func (*Block) Reset ¶
func (b *Block) Reset()
Reset clears the encoded wire buffer, value, and subelements of the block.
func (*Block) Subelements ¶
Subelements returns the sub-elements of the block.
