 int length)

Method Details

estimatedEncodingSize

public int estimatedEncodingSize()

Description copied from interface: IWriteable

Estimate the encoded data size for this Cell. Used for quickly sizing buffers. Implementations should try to return a size that is likely to contain the entire object when represented in binary format, including the tag byte.

Returns:

The estimated size for the binary representation of this object.

equals

public boolean equals(ABlob a)

Description copied from class: ABlob

Determines if this Blob is equal to another Blob. Blobs are defined to be equal if they have the same on-chain representation, i.e. if and only if all of the following are true: - Blob is of the same general type - Blobs are of the same length - All byte values are equal

Specified by:

equals in class ABlob

Parameters:

a - Blob to compare with

Returns:

true if Blobs are equal, false otherwise

equals

public boolean equals(ANumericBlob a)

getChunk

public Blob getChunk(long i)

Description copied from class: ABlob

Gets a chunk of this Blob, as a canonical Blob up to the maximum chunk size. Returns empty Blob if and only if referencing the end of a Blob with fully packed chunks

Specified by:

getChunk in class ABlob

Parameters:

i - Index of chunk

Returns:

A Blob containing the specified chunk data.

isRegularBlob

public boolean isRegularBlob()

Description copied from class: ABlob

Returns true if this object is a regular blob (i.e. not a special blob type like Address)

Overrides:

isRegularBlob in class ABlob

Returns:

True if a regular blob

encode

public int encode(byte[] bs,
 int pos)

Description copied from class: ACell

Writes this Cell's encoding to a byte array, including a tag byte which will be written first. Cell must be canonical, or else an error may occur.

Specified by:

encode in interface IWriteable

Specified by:

encode in class ACell

Parameters:

bs - A byte array to which to write the encoding

pos - The offset into the byte array

Returns:

New position after writing

isCanonical

public boolean isCanonical()

Description copied from class: ACell

Returns true if this Cell is in a canonical representation for message writing. Non-canonical objects may be used on a temporary internal basis, they must always be converted to canonical representations for external use (e.g. Encoding).

Specified by:

isCanonical in class ACell

Returns:

true if the object is in canonical format, false otherwise

getTag

public byte getTag()

Description copied from class: ACell

Gets the tag byte for this cell. The tag byte is always written as the first byte of the Cell's Encoding

Specified by:

getTag in class ACell

Returns:

Tag byte for this Cell
