org.hipparchus.geometry.euclidean.oned.Vector1DFormat

public class Vector1DFormat
extends VectorFormat<Euclidean1D,Vector1D>

Formats a 1D vector in components list format "{x}".

The prefix and suffix "{" and "}" can be replaced by any user-defined strings. The number format for components can be configured.

White space is ignored at parse time, even if it is in the prefix, suffix or separator specifications. So even if the default separator does include a space character that is used at format time, both input string "{1}" and " { 1 } " will be parsed without error and the same vector will be returned. In the second case, however, the parse position after parsing will be just after the closing curly brace, i.e. just before the trailing space.

Note: using "," as a separator may interfere with the grouping separator of the default NumberFormat for the current locale. Thus it is advised to use a NumberFormat instance with disabled grouping in such a case.

Constructor Details

Vector1DFormat

public Vector1DFormat()

Create an instance with default settings.

The instance uses the default prefix, suffix and separator: "{", "}", and "; " and the default number format for components.

Vector1DFormat

public Vector1DFormat(NumberFormat format)

Create an instance with a custom number format for components.

Parameters:

format - the custom format for components.

Vector1DFormat

public Vector1DFormat(String prefix,
 String suffix)

Create an instance with custom prefix, suffix and separator.

Parameters:

prefix - prefix to use instead of the default "{"

suffix - suffix to use instead of the default "}"

Vector1DFormat

public Vector1DFormat(String prefix,
 String suffix,
 NumberFormat format)

Create an instance with custom prefix, suffix, separator and format for components.

Parameters:

prefix - prefix to use instead of the default "{"

suffix - suffix to use instead of the default "}"

format - the custom format for components.

Method Details

getVector1DFormat

public static Vector1DFormat getVector1DFormat()

Returns the default 1D vector format for the current locale.

Returns:

the default 1D vector format.

Since:

1.4

getVector1DFormat

public static Vector1DFormat getVector1DFormat(Locale locale)

Returns the default 1D vector format for the given locale.

Parameters:

locale - the specific locale used by the format.

Returns:

the 1D vector format specific to the given locale.

Since:

1.4

format

public StringBuffer format(Vector<Euclidean1D,Vector1D> vector,
 StringBuffer toAppendTo,
 FieldPosition pos)

Formats a Vector object to produce a string.

Specified by:

format in class VectorFormat<Euclidean1D,Vector1D>

Parameters:

vector - the object to format.

toAppendTo - where the text is to be appended

pos - On input: an alignment field, if desired. On output: the offsets of the alignment field

Returns:

the value passed in as toAppendTo.

parse

public Vector1D parse(String source)
               throws MathIllegalStateException

Parses a string to produce a Vector object.

Specified by:

parse in class VectorFormat<Euclidean1D,Vector1D>

Parameters:

source - the string to parse

Returns:

the parsed Vector object.

Throws:

MathIllegalStateException - if the beginning of the specified string cannot be parsed.

parse

public Vector1D parse(String source,
 ParsePosition pos)

Parses a string to produce a Vector object.

Specified by:

parse in class VectorFormat<Euclidean1D,Vector1D>

Parameters:

source - the string to parse

pos - input/output parsing parameter.

Returns:

the parsed Vector object.
