Class Code

com.mapinfo.midev.util.Code

All Implemented Interfaces:

Serializable

public final class Code
extends Object
implements Serializable

Identifies an object with a code in a codespace. Typically used to represent a projection/coordinate system (e.g. epsg:4326) a Code may be used to represent anything. When expressed as a string a Code is composed of two parts: a codespace, followed by a colon (:), terminated by a code. The meaning of the code is defined by the codespace it is in. For example, 'epsg:4326' means WGS 84 in the epsg codespace. This class holds the codespace/code tuple in one object for ease of use.

Constructor Detail

Code

public Code(String codeSpace,
            String code)

Creates a Code from the specified codeSpace and code.

Parameters:

codeSpace - the codespace of the code (e.g. 'epsg').

code - the code of the Code.

Throws:

IllegalArgumentException - if the specified codeSpace or code is null or empty.

Method Detail

getCodeSpace

public String getCodeSpace()

Returns the codespace of this Code.

Returns:

the codespace of this Code.

getCode

public String getCode()

Returns the code of this Code.

Returns:

the code of this Code.

parse

public static Code parse(String codeSpaceAndCode)

Returns the Code as parsed from the specified String. The string must contain at least one colon (':') surrounded by non-zero characters. The codespace is to the left of the colon while the code is to the right of the colon.

Parameters:

codeSpaceAndCode - the codespace/code pair as a String to parse.

Returns:

the Code as parsed from the specified String.

Throws:

IllegalArgumentException - if the specified string is null does not contain a colon does not contain characters to the left or right of the colon.

toString

public String toString()

Returns the Code as a codespace/code string. The codespace and code will be separated by a colon (e.g. 'epsg:4326').

Overrides:

toString in class Object

Returns:

the Code as a codespace/code string. The codespace and code will be separated by a colon (e.g. 'epsg:4326').

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
