Method Detail

getFixedBitCount

public int getFixedBitCount()

getAlignmentByteCount

public int getAlignmentByteCount(int width)

Description copied from interface: FennelStoredTypeDescriptor

Gets the alignment size in bytes required for values of this type, given a particular max byte count. This must be 1, 2, 4, or 8, and may not be greater than 1 for variable-width datatypes. For fixed-width datatypes, the width must be a multiple of the alignment size.

Specified by:

getAlignmentByteCount in interface FennelStoredTypeDescriptor

Overrides:

getAlignmentByteCount in class FennelStandardTypeDescriptor.FennelType

Parameters:

width - width for which to compute the alignment

Returns:

number of bytes

getMinByteCount

public int getMinByteCount(int maxWidth)

Description copied from interface: FennelStoredTypeDescriptor

Gets the number of bytes required to store the narrowest value with this type, given a particular max byte count. For a fixed-width type, the return value is the same as the input.

Specified by:

getMinByteCount in interface FennelStoredTypeDescriptor

Overrides:

getMinByteCount in class FennelStandardTypeDescriptor.FennelType

Parameters:

maxWidth - maximum width for which to compute the minimum

Returns:

number of bytes

newAttributeAccessor

public FennelAttributeAccessor newAttributeAccessor()

Description copied from interface: FennelStoredTypeDescriptor

Creates an FennelAttributeAccessor appropriate for marshalling an element of this type.

Returns:

FennelAttributeAccessor
