dap4.core.util.MultiSlice

public class MultiSlice
extends Slice

A MultiSlice is a list of slices to support e.g. [x:y,a:b] It subclasses Slice so it can appear in same places slices do; code is expected to differentiate.

Constructor Detail

MultiSlice

public MultiSlice(java.util.List<Slice> subslices)
           throws DapException

Throws:

DapException

Method Detail

equals

public boolean equals(java.lang.Object o)

Compare two slices for equality

Overrides:

equals in class Slice

Parameters:

o - the other slice to compare with

Returns:

true if this and other are the same, false otherwise

hashCode

public int hashCode()

Overrides:

hashCode in class Slice

toString

public java.lang.String toString()

Overrides:

toString in class Slice

toConstraintString

public java.lang.String toConstraintString()
                                    throws DapException

Convert this multislice to a string suitable for use in a constraint

Overrides:

toConstraintString in class Slice

Returns:

constraint usable string

Throws:

DapException

finish

public Slice finish()
             throws DapException

Description copied from class: Slice

Perform sanity checks on a slice and repair where possible.

Overrides:

finish in class Slice

Returns:

this (fluent interface)

Throws:

DapException - if slice is malformed

getSubSlices

public java.util.List<Slice> getSubSlices()

Overrides:

getSubSlices in class Slice

getSubSlice

public Slice getSubSlice(int i)

Overrides:

getSubSlice in class Slice

getCount

public long getCount()

Description copied from class: Slice

Compute the number of elements in the slice. Note that this is different from getStop() because stride is taken into account.

Overrides:

getCount in class Slice

setMaxSize

public Slice setMaxSize(long size)
                 throws DapException

Overrides:

setMaxSize in class Slice

Throws:

DapException
