PrimArray	arrayFromBuffer(java.lang.Object buffer) Make an array with the values at the given address
int	bitCount() How many bits, or zero if it is unlimited
boolean	canHold(IntegerValue value) Return true if this specification can hold the given value.
PrimIntegerSpec	combine(PrimIntegerSpec other) Return a specification whose range of values contains the ranges of both this and other.
boolean	isEqual(Heaper other) Return true if the two objects are equal.
boolean	isSigned() Return true if this specifications values may be negative.
PrimArray	privateCopy(PrimArray array, int size, int start, int count, int offset) Make a copy of an array with a different representation size.
PrimIntegerArray	string(java.lang.String string) Make an array the contents of the string

Constructor Detail

PrimIntegerSpec

protected PrimIntegerSpec(java.lang.Class arrayClass,
                          int bitCount,
                          boolean isSigned)

Construct a new specification for integer values.

Parameters:

arrayClass - the type of PrimArray used to hold values that meet this specification

bitCount -

isSigned - true if values can be negative and positive

Method Detail

bitCount

public int bitCount()

How many bits, or zero if it is unlimited

isSigned

public boolean isSigned()

Return true if this specifications values may be negative.

Returns:

true if this specifications values may be negative.

combine

public PrimIntegerSpec combine(PrimIntegerSpec other)

Return a specification whose range of values contains the ranges of both this and other.

Parameters:

other - other range of values to contain

actualHashForEqual

public int actualHashForEqual()

Description copied from class: Heaper

Defined by subclasses to produce the value returned by hashForEqual.

Overrides:

actualHashForEqual in class PrimSpec

canHold

public boolean canHold(IntegerValue value)

Return true if this specification can hold the given value.

Parameters:

value - integer value to test against.

Returns:

true if this specification can hold the given value.

isEqual

public boolean isEqual(Heaper other)

Description copied from class: Heaper

Return true if the two objects are equal.

Specified by:

isEqual in class Heaper

arrayFromBuffer

public PrimArray arrayFromBuffer(java.lang.Object buffer)

Make an array with the values at the given address

Specified by:

arrayFromBuffer in class PrimSpec

Parameters:

buffer - Java array containing elements meeting this specification.

Returns:

the array

string

public PrimIntegerArray string(java.lang.String string)
                        throws java.io.UnsupportedEncodingException

Make an array the contents of the string

java.io.UnsupportedEncodingException

value

public IntegerValue value(int number)

A boxed integer value

privateCopy

public PrimArray privateCopy(PrimArray array,
                             int size,
                             int start,
                             int count,
                             int offset)

Make a copy of an array with a different representation size. The arguments are the same as in PrimArray::copy.

Specified by:

privateCopy in class PrimSpec
