AObject

public AObject()

Method Details

print

public abstract boolean print(BlobBuilder sb,
 long limit)

Prints this Object to a readable String Representation. SECURITY: Must halt and return false in O(1) time when limit of printing is exceeded otherwise DoS attacks may be possible.

Parameters:

sb - BlobBuilder to append to. May be partially written if print limit exceeded

limit - Limit of printing in string bytes

Returns:

True if fully printed within limit, false otherwise

print

public final AString print()

Prints this Object as a CVM String value, for human consumption. May include readable message indicating failure if print limit exceeded.

Returns:

String representation

print

public final AString print(long limit)

Prints this Object as a CVM String value, for human consumption. May include readable message indicating failure if print limit exceeded.

Parameters:

limit - Limit of bytes to print

Returns:

String representation

getEncoding

public Blob getEncoding()

Gets the encoded byte representation of this value.

Returns:

A Blob representing this value in encoded form

createEncoding

protected abstract Blob createEncoding()

Creates a Blob object representing this object. Should be called only after the cached encoding has been checked.

Returns:

Blob Encoding of Object

attachEncoding

public final void attachEncoding(Blob data)

Attach the given encoded Blob to this object Warning: Blob must be the correct canonical representation of this Cell, otherwise bad things may happen (incorrect hashcode, etc.)

Parameters:

data - Encoding of Value. Must be a correct canonical encoding, or null to clear the cached encoding
